2.2 Brief Description of nature of Product:

2.2.1 Sugar

Sugar known as sucrose or saccharose is an anhydrous crystalline organic product of

comparatively 99.96% purity. The physical properties of sucrose are defined as follows

CRYSTALLINE NATURE:

Sucrose crystals are hard and belong to the mono-clinic system, characterized by three

axes of unequal length. Density of sucrose is equal to 1.606 gm/cu.cm. The presence of

impurities in sugar have a remarkable influence on the formation of the crystals.

SOLUBILITY:

Sucrose is very soluble in water and in dilute ordinary alcohol. The solubility in water

increases with the rise in temperature, such that for a 10% sucrose solution, the boiling point

is 100.04 Deg.C and for a 90% sucrose solution the boiling point is 130 Deg.C. It is insoluble

in chloroform, in cold absolute alcohol, either and glycerine.

SPECIFIC GRAVITY:

The specific gravity of sucrose varies from 1.033 to 1.106 according to the concentration of

the solution. The density of the sugar solution is determined in practice by brix and baume

spindles or balling saccharimeter.

OPTICAL ROTATION:

Sucrose and glucose rotate the plane of the polarised light in a `clockwise‘ direction or to the

right and is called dextro-rotatory. Fructose, rotate in a `counter clock wise‘ direction or to the

left and is known as levo-rotatory. The specific rotation of sucrose is 66.5 Deg.

CHEMICAL PROPERTIES:

Dry sugar (sucrose) melts at 160 Deg.C into a thick transparent liquid which on cooling again

becomes crystalline. If heated for a long time at 160 Deg.C sucrose splits up into glucose

and levulosane. At higher temperatures between 190 to 220 Deg.C the decomposition is

more complete and caramel is produced. On further, heating, carbondioxide, carbon

monoxide, acetic acid and acetone are produced.

In the presence of moisture, sucrose decomposes at 100 Deg.C and becomes dark in colour

liberating water. On prolonged heating of sucrose at the boiling point and at ordinary

pressures, the dissolved sucrose combines with water and breaks up into glucose and

fructose in equal parts and the phenomenon is called Hydrolysis of Inversion.

APPLICATIONS:

The principal use of sugar as explained is as the sweetening agent in foods. The

consumption of sugar is distributed in the various sectors such as for daily human

consumption in household sector for food processing industries, beverages, baking industry,

confectioneries and miscellaneous users. Sucrose serves as raw materials for manufacture

of glucose, fructose, invert sugar syrups etc.

Non-food uses of sugar constitute a small amount of total sugar consumption. They include

use of sugar as a octacetate, a denaturant in ethyl alcohol, as sucrose diacetate, Hexa-

isobutyrate, octa benzoate, as mono and difatty acid esters for surfactants, as allyl sucrose,

in plasticisers and as raw materials for manufacture of various chemicals like glycerol,

mannitol etc.

Dextran is a polysaccharide produced from sucrose by the biological process and is a very

effective plasma volume expander. Sucrose when administered by intravenous infusion

relieves shock and prevents loss of body fluids after excessive burns, wounds or infectious

diseases. Other industries wherein sucrose is finding application towards drying oil esters

for surface coating industries and sugar derived detergents.

2.3 Demand – Supply Gap:

The sugar industry today is facing fierce competitive situation due to fluctuations in sugar

prices in the national & international markets, higher cane prices to be paid to the cane

growers, rising input costs, etc. The survival and growth of this industry depends on energy

efficiency, cost optimization and revenue generation from bi-products and down steam

products including power, ethanol, chemicals, etc.

The implementation of co-gen power plant concurrently with the sugar modernization cum

expansion project along with other by-products, right from the beginning goes a long way to

integrate the operations and improve sustainability.

Sugar Industry Overview

The origin of Indian sugar industry dates back to 1930, when the first sugar factory was set

up in the pre-independence era. Over the last 76 years, the sugar industry has steadily

grown and has become the backbone of the agricultural and rural economy in India. Today,

sugar is the second largest agro processing industry, next to the textile industry. India is one

of the largest producers of sugar in the world, with a production of over 15 million tones.

Sugar factories are located mostly in the rural India. They act as centers of development,

provide largest direct employment in the rural areas and contribute substantially to the

Central and State exchequers. The prospects of earning foreign exchange from export of

sugar are also quite high.

Sugar factories in India have capacities ranging from 1250 TCD to 20,000 TCD. The Indian

sugar industry has developed indigenous capabilities for design, manufacture, supply,

operation and maintenance, R&D and cane development. The major stakeholders of this

industry in India are Ministry of Agriculture, Govt. of India, Ministry of Consumer Affairs,

Food and Public Distribution, federations of co-operative and private sector sugar factories

at the national and the State levels, sugarcane growing farmers, equipment and technology

suppliers, research institutions, consultants and service providers, financial institutions and

Central / State Governments.

A total of 727 sugar factories are in operation today, with additional few new sugar factories

under implementation in different parts of the nation. The area under sugar cane cultivation,

sugar cane production, sugar cane crushing in sugar factories, average season days, sugar

recovery and sugar production has increased steadily over the years. The crop yield per

hectare and recovery has improved, particularly in the last decade.

The Ministry of Consumer Affairs, Food & Public Distribution, and Government of India

revised the standard specifications for sugar plant & equipment, in the year 1987. The

special committee finalized specifications for economical capacity of 2500 TCD, expandable

to 3500 TCD, employing higher-pressure boiler and turbine configuration and efficient

equipment, with a potential to export incidental surplus power to the grid.

The Indian sugar industry was de licensed in the year 1998 vide press note No. 12 issued by

the Government of India, Ministry of Industry, Department of Industrial Policy and Promotion,

on August 31, 1998. The salient features of de licensing are as follows:

The sugar industry stands deleted from the list of industries requiring compulsory

licensing under the provisions of Industries Development and Regulation Act, 1951.

However, in order to avoid unhealthy competition among sugar factories to procure

sugarcane, a minimum distance of 15 km would continue to be observed between

and existing sugar factory and a new factory, by exercise of powers under the Sugar

Control Order, 1966.

The entrepreneurs, who wish to de-license their sugar factory, would require filing an

Industrial Entrepreneur Memoranda (IEM) with the secretariat of industrial assistance

in the Ministry of Industry, as laid down for all de-licensed industries, in terms of the

press note dated August 2, 1991, as amended from time to time.

Entrepreneurs who have been issued Letter of Intent (LoI) for manufacture of sugar

need not file an initial IEM. In such cases, the LoI holder shall only file Part B of the

IEM at the time of commencement of commercial production against the LoI issued

to them. It is however open to entrepreneurs to file an initial IEM (in lieu of LoI /

industrial license held by them) if they so desire, whenever any variation from the

conditions and parameters stipulated in the LoI / industrial license is contemplated.

The statistics on economic and commercial performance for the industry is quite fluctuating.

The changes in the agro climatic conditions and sugarcane crop production, as well as the

sugar markets have been mainly responsible for these fluctuations. Efficiency, quality, and

integration have become order of the day for this industry. The industry has grown till today

over the last seven decades. The strength and capacity built so far will surely help meet

these challenges. The following are major options to meet these challenges:

a. Effecting substantial improvement in cane development and management,

including cultivation practices, varietals and water management, so as to improve

yield and recovery, without affecting the average fibre content.

b. Effecting visible improvement in the operational efficiencies and reduction of sugar

losses.

c. Effecting and sustaining improvement in energy efficiency, both in steam and

power, for saving of additional bagasse, for both sugar and by-products

manufacture.

d. Effecting adequate capacity building within and without.

e. Maximizing sugar exports for value addition.

f. Effective marketing in the national and international markets.

g. Product quality and diversification.

h. Commercializing the excess power capacity by exporting to utilities or to other bulk

power consumers.

Ministry of Consumer Affairs, Food & Public Distribution Department of Food & Public

Distribution Government of India has issued a revised order dated November 10, 2006,

Ethanol Sector Overview

The use of alcohol as a drink is an age-old story. It appears that in India the technique for

fermentation and distillation was available even in the Vedic times. Alcohol is an integral part

of the Ayurvedic system of medicine also.

Carew & Co. Ltd. set up the first distillery in the country at Cownpore (Kanpur) in 1805 for

manufacture of Rum for the British army. The technique of fermentation, distillation and

blending of alcoholic beverages was developed in India on the lines of practices adopted

overseas, particularly in Europe.

The original use of alcoholic fermentation was of course for preserving fruit juices. Now the

fermentation is adapted for the preparation of fermented grain beverages and then distilled

beverages. The utilization of Ethanol, for industrial use is a recent phenomenon. It became

important towards the end of the Second World War.

When large-scale production of alcoholic beverages was taken up, various Governments

found that alcohol was a good source for increasing government revenue through collection

of tax. When synthetic organic chemistry advanced rapidly, about a century ago, alcohol

became an indispensable chemical for this industry. However extensive manufacturing of

alcohol for industrial use was hampered due to excessive taxes. The problem was to device

a means for conserving government‘s interest in tax collection on potable alcohol and at the

same time making alcohol for industrial use relatively free of tax. Thus different governments

introduced the process of denaturation of alcohol for industrial use.

During the Second World War, the demand for the industrial alcohol increased 4-5 times,

above the prewar period, due to the production of smokeless powder for weapons. The

imports of molasses were hampered due to war conditions. This leads to evolving the

process of grain fermentation for meeting the requirement of Ethanol.

In India, after the protection granted to the sugar Industry in 1932, a large number of sugar

factories were established in the country, particularly in Maharashtra and Uttar Pradesh

where irrigation facilities existed for cultivation of sugarcane. Increase in sugar production

resulted in accumulation of molasses, which resultantly, caused unmanageable

environmental problems. At that time the demand for molasses was almost insignificant and

the sugar mills had to incur considerable expenditure for disposal of molasses. For resolving

these problems a joint committee of U.P. and Bihar was constituted in 1938 to explore the

possibilities of using molasses for developing alcohol-based industries. The Committee

recommended establishment of distilleries for production of alcohol, utilizing molasses as a

substrate.

The committee also recommended that alcohol produced by the distilleries should be

admixed with petrol, to supplement motor fuel. This helped in solving the problems of

disposal of molasses. It also filled up the gap in the demand and supply of motor spirit.

As a result, after meeting alcohol requirement for manufacture of gasohol, substantial

quantity of alcohol was diverted for production of alcohol based chemicals.

Present Status

Fossil fuels are declining. Transportation sector consumes more than 50% of the fuels.

Environmental degradation from these fuels is a major problem all over the world. World oil

production is expected to last till 2125 A.D., if consumption at the present level is

maintained. On this background the use of Ethanol for fuel blending should be given a top

priority.

India requires ethanol for the following three major purposes:-

For potable liquor

For industrial use

For fuel blending

Today, the distillery industry of India uses only molasses for manufacturing alcohol. There

are handful of grain distillery units (e.g. Seagram Manufacturing Ltd.) and the alcohol

produced by them is used for captive use to make value added liquors.

All other liquor (IMFL) manufacturers use alcohol produced from molasses. In advanced

countries, liquor for human consumption is made only from grain alcohol. It is known that

alcohol produced from molasses can have residues such as sulphates, sulphites, higher

aldehydes, higher alcohols, higher acids and ketones etc., which are not present in alcohol

from, grains.

However, no such above-mentioned distinction is made in India. Thus alcohol produced only

from one source i.e. molasses is used for all 3 purposes (liquor, industrial use, fuel

blending). There is an urgent need to bring in above quality consciousness in the IMFL

industry and appropriate policy measures by the Govt.

Today, Indian distillery industry broadly consists of two parts:

One is alcohol production from molasses for industrial alcohol and two alcohol production

from molasses for liquor purposes.

Ethanol demand for fuel blending is a recent phenomenon. For this purpose, alcohol from

molasses is used.

The potable distillery producing Indian Made Foreign Liquor (IMFL) has a steady but limited

demand. The alcohol produced is now being utilized in the ratio of approximately 52 per cent

for potable purpose and the balance 48 percent for industrial purpose.

Ethanol blending

Ethanol blending is the practice of blending petrol with ethanol. Many countries, including

India, have adopted ethanol blending in petrol in order to reduce vehicle exhaust emissions

and also to reduce the import burden on account of crude petroleum from which petrol is

produced. It is estimated that a 5% blending (105 crore litres) can result in replacement of

around 1.8 million Barrels of crude oil . The renewable ethanol content, which is a byproduct

of the sugar industry, is expected to result in a net reduction in the emission of carbon

dioxide, carbon monoxide (CO) and hydrocarbons (HC). Ethanol itself burns cleaner and

burns more completely than petrol it is blended into. In India, ethanol is mainly derived by

sugarcane molasses, which is a by-product in the conversion of sugar cane juice to sugar.

The practice of blending ethanol started in India in 2001. Government of India mandated

blending of 5% ethanol with petrol in 9 States and 4 Union Territories in the year 2003 and

subsequently mandated 5% blending of ethanol with petrol on an all-India basis in November

2006 (in 20 States and 8 Union Territories except a few North East states and Jammu &

Kashmir). This was also an attempt to reduce the Under-recovery of Public Sector Oil

Marketing Companies (OMCs). Ministry of Petroleum and Natural Gas, on 1 September,

2015, inter-alia has asked OMCs to target ten percent blending of ethanol in Petrol in as

many States as possible. In countries like US, blending is allowed upto 10%. Subsequent to

Brazil's bio-fuel programme, which began in 1976, close to 94% of cars sold in Brazil are

flexible fuel cars that can handle ethanol blends from 18 per cent upward .

Ethanol blending first found mention in the Auto fuel policy of 2003. It suggested developing

technologies for producing ethanol/ bio fuels from renewable energy sources and introducing

vehicles to utilise these bio fuels. Later, as per National Policy on Bio-fuels, announced in

December 2009, oil companies were required to sell petrol blended with at least 5% of

ethanol. It proposed that the blending level be increased to 20% by 2017.

Ethanol, being a by product of the sugar industry, was expected to be freely available.

However, Oil marketing companies (OMCs) were not even able to get bids for more than

50% of the amount offered for purchase . Further, the Government decided on 22.11.2012

that procurement price of ethanol will henceforth be decided between Oil Marketing

Companies (OMCs) and suppliers of ethanol. In addition, on 03.07.2013, it was decided that

ethanol would be procured only from domestic sources. This led to a rise in ethanol prices,

which to a great extent reportedly eroded the economy of the blend. At present, government

has permitted OMCs to implement the ethanol blending programme in notified 20 States and

4 Union Territories as per the availability of ethanol.

There are reportedly significant transaction barriers which impede smooth supplies of

ethanol for blending. In several States, State not only imposes levy on molasses but also

regulates the movement of non-levy molasses. Inter-state movement of ethanol requires No-

Objection-Certificates (NOCs) from the State Excise Authorities along with permits from

dispatching and receiving States. Most States impose ―Export/Import‖ duties on ethanol

leaving and entering their boundaries. There are some instances where Octroi is levied on

ethanol for entry into municipal limits. Hence States were requested by the Central

Government to liberalise restrictions on the supply of ethanol so that its blending with petrol

can be encouraged while improving the financial health of sugar sector and also liquidation

of cane dues of farmers.

As per the estimates given in Auto Fuel Vision and Policy 2025 issued in May 2014, blended

petrol is available only in 13 states and the average blend is 2%. During the sugar year

2014-15, OMCs have achieved a blending percentage of 2.3% as per the press release

dated 25 April 2016.

Hence, in order to improve the availability of ethanol, the Government, on December 10,

2014, fixed the price of Ethanol in the Range of Rs. 48.50 to Rs. 49.50, depending upon the

distance of distillery from the depot/installation of the OMCs. (The rates are inclusive of all

central and statutory levies, transportation cost etc, which would be borne by the Ethanol

suppliers). Fixation of ethanol price based on distance, has encouraged movement of

ethanol to longer distances, including States having lack of distilleries. Further, ethanol

produced from other non-food feedstocks besides molasses, like cellulosic and ligno

cellulosic materials including petrochemical route, has also been allowed to be procured

subject to meeting the relevant Bureau of Indian Standards (BIS) specifications.

2.4 Employment generation (Direct & Indirect):

The man power required for the proposed expansion will be 120 Nos. which is inclusive of

30 nos. on permanent basis and rest all will be on Temporary or contract basis.

3.5.1 Sugar Process Description

Sugar is nothing but sucrose in its purest crystal from. While sugar is produced from

sugarcane in India, it is produced from sugar beet in the European countries, which requires

cold climatic conditions for its growth. Basically, sugarcane contains 14% to 17% Fiber, 16

to 24% Dissolved solids and the rest is all water. About 80% to 87% of the dissolved solids

in sugarcane are sucrose solids. Hot day and cold night climate (maximum difference of

temperature between day and night) is the favorable weather condition for sugarcane

growth. The task of the sugar factory is to extract maximum sugar from sugarcane with

minimum losses and at minimum expenditure by adding value of its bye-products.

We can divide the process operations of sugar manufacture into 6 steps namely,

1. Juice Extraction

2. Juice clarification

3. Evaporation

4. Crystallization

5. Centrifugation

6. Drying, Bagging & storing

JUICE EXTRACTION:

Juice is stored in the fibrous cells of the sugarcane stalk. We have to break open these cells

and squeeze the juice out for processing. For this, sugarcane is made into small pieces by

the preparatory devices, which cut the sugarcane using knives. These pieces are further

processed at the fibrizer of shredder where they are pealed into fibrous shape. This finely

prepared sugarcane is subjected to compressions at mills where juice is extracted. The

residue from mills called bagasse has the character of re-absorption. Hence, it absorbs juice

back into it when it is released from mills. To extract this juice also, water is sprayed into the

bagasse mat at the point where it comes out from mills. This water will penetrate in to the

cells and dilute the juice remaining in them. This diluted juice is again extracted in next

compression. Like this, the prepared cane is subjected to 4 to 5 compressions to extracts

maximum juice from sugarcane. Juice from all compressions is collected, weighed and sent

to processing house for reaping out the sugar.

Bagasse leaving the last mill is sent to boilers for generating steam. This steam is used for

producing power by the turbo-generator, which is used for operating the machinery in

factory. The exhaust steam leaving the turbine is used in the boiling house for various

process operations.

JUICE CLARIFICATION:

Weighed juice from milling plant is pumped to boiling house for clarification. The juice is first

subjected to heating in a tubular heater, where juice is passed inside the tubes and steam is

applied externally, to heat it to 700C. This hot juice is sent to reaction vessel where Milk of

Lime {Ca (oH)2} and sulfur-Di-oxide gas (SO2) are mixed. These chemicals will react with

Phosphates present in juice in the form of P2O5 and produce precipitates of Ca3 (PO4)2 and

CaSO3. These precipitates (called Mud) will absorb all the impurities in juice such as

Page 19: PRE- FEASIBILITY REPORT - environmentclearance.nic.inenvironmentclearance.nic.in/writereaddata/Online/TOR/24_Nov_2017... · PRE- FEASIBILITY REPORT ... The specifications required

suspended matter, waxes, gums, pectines, coloring matter, etc. This treated juice is

subjected to heating again to its boiling temperature, i.e. around 1030C. This juice is sent to

settling tank called clarifier for settling the mud through a flash tank where excess heat and

dissolved gases like Ammonia present in the juice are vented to atmosphere, which if

permitted to enter the clarifier will disturb the settling process.

Mud is settled t the bottom in the clarifier and clear juice is taken out from the top. The mud

is mixed with bagacillo, fine powder of bagasse, and subjected to filtration at vacuum filters

for recovering the juice in it. This juice called filtrate juice is mixed to the weighed juice

received from mills for subjecting it to clarification.

EVAPORATION:

Clear juice from clarifier contains around 14% solids only and the rest is all water. This juice

is sent to multiple effect evaporator station for concentrating to 60 to 65% solids. Vapor

produced in one body of the evaporator set is used as heating medium for the next body by

maintaining differential pressures in each body; thereby lot of steam economy is ached. This

thick juice called syrup is subjected to sulphitation for removing coloring matter from it.

CRYSTALIZATION:

Thick, sulphited syrup from evaporator set is boiled again in vacuum pans for further

concentration. When the syrup is continued to boil above its saturation point, sucrose in

dissolved from in the syrup will come out as crystal. This liquid –crystal state of the material

is called Massecuite. We can control the crystal growth by maintaining saturation level in

pan by feeding sulphited syrup and continuing boiling. Since the saturation state is

maintained, sucrose in syrup will keep depositing on the already formed crystal, and hence

the crystal size increase. Once the sugar crystal attains required size, the Massecuite is

forwarded into a storage vessel called crystallizer, before it is sent for liquid-crystal

separation. This first grade Massecuite is called A-Massecuite. The liquid portion of this

mass is called molasses and it still contains some sugar. The reap out that sugar also, this

molasses is taken into masse is called B-Molasses. Sugar is melted and taken to first stage

boiling. The second stage masse is called B-Massecuite. This is subjected to centrifugation

separately for separating B-sugar and B-Molasses. Sugar is melted and taken to first stage

boiling. The second molasses called B-Molasses also contains some sugar. Hence this is

again taken to pans for boiling third grade Massecuite called C-Massecuite. This

Massecuite contain more non sugar solids and recoverable sugar is less compared to first

Page 20: PRE- FEASIBILITY REPORT - environmentclearance.nic.inenvironmentclearance.nic.in/writereaddata/Online/TOR/24_Nov_2017... · PRE- FEASIBILITY REPORT ... The specifications required

two stages. This Massecuite is centrifuged in continuous centrifugals to separate sugar and

molasses.

Molasses from this third grade Massecuite contain some more sugar, but cannot be

extracted due to presence of heavily concentrated non sugars. Hence this molasses called

Final molasses will be used as raw material for production of Alcohol & Motor spirit or

Ethanol.

CENTRIFUGATION:

Centrifugation is the stage where liquid and crystal portion of the Massecuite are separated.

The separation is achieved by subjecting the Massecuite to centrifugal force in a cylindrical

or conical shaped basked to which screens of micro openings (0.4 mm for cylindrical baskets

and 0.05 mm to 0.09 mm for conical shaped baskets) are fixed through which liquid portion

is separated. First grade Massecuite is less viscous and can be separated freely from a

thick cake. Hence, this is centrifuged in batch type centrifugal. This cycle contain series of

operations such as charging of Massecuite into the machine, spinning to purge out the

molasses, washing the sugar cake for removing the molasses film on crystals, drying by

spinning at high speed and automatic discharge of sugar on to hoppers for further drying to

first grade Massecuite. Hence these Massecuite are centrifuged in machines with conical

shaped basket, called continuous centrifugal machines.

DRYING, BAGGING & STORING:

Sugar, as it is discharged from centrifugal on to the hoppers contain moisture and cannot be

bagged directly. While the sugar travel forward on the hopper, hot air at around 600C is

blown through the sugar crystals to evaporate excess water on the surface. The time the

excess water is evaporated, sugar gets heated up because of the hot air. Hence cold air is

blown again through the dried sugar crystals to bring down the temperature to around 400C.

Dried and cooled sugar is passed through grader to separate lumps, powder and for size

separation. Larger size crystals are called ‗M‘ sugar and smaller size crystals are called ‗S‘

sugar. These two sugars are stored in separate bins for bagging.

Sugar is packed in 50 Kgs PP bags or 100 Kgs jute bags, depending on the market demand,

and stored in warehouse in stacks.

PROCESS DESCRIPTION OF PRODUCING WHITE SUGAR FROM IMPORTED RAW

SUGAR.

Imported raw sugar from 2 tons jumbo bags is dumped into the 4 tons capacity storage bin

located inside the sugar godown with the help of crane. Raw sugar from this bin is fed to a

horizontal sugar melter through a feeding device called rotary valve for continuous and

uniform feeding. Hot water is added in the melter to maintain melt liquor consistency. The

sugar melt liquor is then passed on to a vibratory mesh to remove any foreign material in it.

It is then let into the pump receiving tank from where it is pumped through pipe line to

processing house.

The sugar melt liquor from here is mixed in the regular process scheme that is adopted for

making sugar from sugar cane.

At first, the sugar melt liquor is clarified to remove dissolved colour and other impurities

using chemicals such as colour precipitant, phosphoric acid and lime. Clear melt is pumped

to storage tanks at vacuum pan station from where it is taken into vacuum pans for

evaporation for re-crystallization.

3.5.2 Co-generation Power Plant

Sugar plant will be expanded to 3500 TCD from 7500 TCD. The cogeneration capacity is so

designed that the plant will be able to feed steam and power requirements entire Sugar

Complex. The capacity of the boiler will be 100 TPH at 110 ata and 540+/- 5 deg C. The

turbine capacity would be 20 MW at 110 ata and 545 ºC steam parameters. The new turbine

will be of Extraction-cum-condensing type.

For off-season operation, we will utilize the purchased biomass fuel, saved bagasse and

imported coal. The season period will be 5 to 6 months and off-season will be 3 to 4 months

depending on the availability of fuels at economical price.

3.5.3 Manufacturing Process (Rectified Spirit/Ethanol/ENA)

Yeast propagation:

Yeast seed material is prepared in water-cooled yeast vessels by inoculating molasses with

yeast. The contents of the yeast vessel are then transferred to the Yeast activation vessel.

The purpose of aerated yeast activation in the yeast activation vessel is to allow time for the

yeast cell multiplication.

Fermentation:

The fermentation technology adopted in the industry is of continuous fermentation with yeast

recycle with this technology the total spent wash generation will be restricted to a max. of 10

kl/kl of R.S. (As per latest CPCB recommendation).

The purpose of fermentation is to convert the fermentable sugars into alcohol. During

fermentation, sugars are broken down into alcohol and carbon-di-oxide. Significant heat

release takes place during fermentation. However the fermentation temperature is

maintained at 32 – 35 0C by forced recirculation heat exchangers.

At the end of fermentation, the wash is fed through a yeast separator where the yeast cream

is separated, acidified in the yeast treatment tank and returned to the yeast activation vessel

for activation. Sludge is separated in a sludge decanter. The clear wash from both the yeast

separator and sludge separator flows to the clarified wash tank. The wash is then pumped to

distillation.

Distillation:

Fermented Wash about 8% v/v alcohol is preheated in two stages i.e. in the beer heater

using the Rectifier vapours and then in the Fermented wash PHE using the effluent. The

preheated wash is then fed the Degasifying Column to remove residual CO2 and volatiles.

The wash then flows down to Analyser Column, which acts as a total stripper. The alcohol

water vapour mixture which rises upward in this column is fed to the Rectifier Column. The

spent wash, which is devoid of alcohol, flows down the Analyser Column for suitable

treatment.

The lower boiling impurities are concentrated in the Aldehyde Column where about 5% spirit

is drawn off as impure spirit with a minimum strength of 660 OP.

The alcohol vapours are concentrated in the Rectifier Column to produce Rectified Spirit of

95% v/v strength. Higher boiling impurities, which are formed during fermentation, are

removed by taking side draw purges to a decanter from the Rectifier Column. A trace stream

of spirit is drawn off as impure spirit (about 2% of plant capacity) to remove the concentrated

volatile compounds. The high grade Rectified Spirit is taken as a draw from the upper trays

of the Rectifier Column.

The Rectified spirit is fed to the purification column. Dilution water is fed on the top most tray

of the column with a dilution ratio of 1: 9. This column serves to remove the impurities based

on the principle of HYDROEXTRACTION. The water is fed to the column in such a way that

it selects the higher alcohols and other impurities to move upwards and extracts ethanol

down. The purifier bottom alcohol composition is maintained at 12 % v/v. At this

composition there is an inversion in relative volatiles of higher alcohols as compared to

ethanol and these alcohols get separated in the top distillate. Top draw for volatiles is fed to

the Fusel oil concentration column.

The purified dilute ethanol is removed from the bottom of the purification column and fed to

the rectification column, which concentrates the ethanol to 96% v/v. The high grade spirit is

drawn from one of the upper trays of the rectification column. A small heads cut is removed

from the overhead stream as technical alcohol (T.A.) cut to with draw impurities and is fed to

the heads concentration column. The lees from the exhaust column is recycled as dilution

water after a part of it is purged. The purged spentlees is used to preheat the make-up

dilution water.

Lower side draw streams are taken from rectification column to avoid fusel oil build up in the

column. These streams are then taken to the fusel oil column. This column concentrates

the dilute streams of ethanol containing esters and fusel oils to approximately 95% v/v of

ethanol. The concentrated ethanol is removed as T.A. cut from the top of the column. T.A.

cut is removed out of the system in order to remove propanol and remaining is fed to the

heads concentration column where the heads from the purification column and rectification

are fed to the static mixer. Soft water, which has been preheated, is used for diluting the

high proof ethanol. An impure spirit cut of about 5% of the rectified spirit feed is drawn from

the top of the column. The dilute ethanol solution at the bottom of this column is pumped

back to the purification column for repurification.

Carbon Dioxide Recovery System (By Product):

Carbon dioxide produced during fermentation will be recovered by means of scrubbing

arrangement, chemical treatment drying process and finally liquefaction. The water utilized

for scrubbing will be recycled back into the fermentor.

CO2 gas will pass through scrubbing tower, where the gas is scrubbed with water. From the

scrubber after washing the gas will pass through air compressor and then the gas will pass

through a tower containing sodium dichromate to eliminate the impurities, if any and then to

drying arrangement with sulphuric acid. Subsequently it passes through a tower containing

coke coated with washing soda to eliminate odour. Finally it goes to the chilling unit to cool

the gas before passing through different cylinders, where the cooled gas will be filled into the

cylinders under pressure. The scrubber blowdown will be recycled into the fermenters.

Total CO2 production : 45.6 T/day

This carbon dioxide in cylinders will be sold to industries like soft drink manufacturing units,

etc.

Ethanol Production:

This plant is filled with imported 3A grade Molecular Sieve. It is operated with vaporized

Alcohol and removes water completely. Then Molecular sieves are regenerated under

vacuum of 710 mm Hg. Feed Alcohol comes to this Plant in a Day Tank continuously from

bulk storage tank. From this tank alcohol is pumped to a steam vaporizer at 4 Kg/cm2

pressure. This is vaporized in a steam heater and then vapor is super heated to 160oC in a

super heater and taken to Molecular Sieve Unit. This super heated vapor now pressure

through one Molecular Sieve column for moisture removal. There are 2 Molecular Sieve

columns. At a time one column remain in drying cycle while other columns under goes

vacuum regeneration. Each column remains in cycle for 6 minutes. Here drying process

takes place at 3.0 Kg/cm2 pressure and dry alcohol vapor of 99.8% purity comes out as final

product. This alcohol vapor is condensed in a water cooler and then collected in another day

tank. From this tank dry alcohol is continuously pumped to bulk day storage tank through a

level controller and a control valve. In the regeneration process some left over alcohol also

comes out which is condensed in regeneration condenser. This alcohol is around 95%

strength and is re-cycled in to rectifier column continuously.

The other Molecular Sieves column under goes regeneration by a vacuum pump. In this

column vacuum pumps pulls and creates vacuum of 710 mm Hg. At this vacuum the

moisture from Molecular Sieve pores comes out and along with 30% pure alcohol from on

line Mole Sieve bed is sprayed. Thereafter during vacuum process, some left over alcohol

and water from Molecular Sieves comes out and is condensed. Concentration of this lean

alcohol is around 70% alcohol, which can be recycled to the Rectifying Column. From

Rectifier the pure water will be sent out automatically.

and continuous mixing of lime. Lime solution is then feed to equalization tank for pH correction

in a required proportion. 1 HP agitator shall be provided for mixing in the tank content.

Equalization:

Wastewater emanating from sugar has fluctuations in wastewater quality and quantity.

Equalization tank shall be provided for dampening these fluctuations. In equalization tank the

raw effluent is collected and equalized for adequate time. An equalization tank shall be

provided with an agitator to mix the tank content thoroughly. The equalized effluent from

equalization tank shall then be pumped to buffer tank. A stand by floating mixer shall also be

provided for equalization tank

Buffer Tank:

Buffer tank constructed in RCC shall be provided for preconditioning / pre-acidification of the

raw effluent. In buffer tank the Raw Effluent is mixed with treated effluent form UASB Reactor.

The nutrient required for the process will also be added to the effluent in Buffer tank. The

content of buffer tank shall be mixed hydraulically using UASB Reactor feed pumps. The tank

content will then be pumped to UASB Reactor for first stage biological treatment.

UASB Reactor:

Upflow Anaerobic Sludge Blanket reactor is provided for anaerobic treatment of Sugar plant

effluent. The UASB reactor shall be constructed in RCC M-25. The reactor consists of three

zones viz. Influent distribution zone, Reaction zone, Gas solid liquid separation zone.

Influent Distribution zone: The raw wastewater enters into the at the bottom through influent

distribution zone. A sophisticatedly designed piping network is provided for uniform distribution

of the effluent in the tank. The effluent then travels upward in the reactor.

Reaction Zone: In the reaction zone the anaerobic bacteria are maintained in the form of

sludge blanket. The organic matter in the wastewater comes in contact with the bacterial

population and is degraded anaerobically to methane rich biogas, the end product of

anaerobic digestion. The process of conversion of organic matter in to the biogas is a two-

stage process. In the first stage the organic matter in the raw effluent is converted in to the

volatile acids by acid forming bacteria. In the second stage the acid produced in the first stage

are converted in to methane by another group of bacteria i.e. methane formers. In UASB

process both the stages are completed in single reactor. The biogas so produced is bubbled

through the effluent and is separated out in the third section i.e. Gas-Solid-Liquid separation

zone. The suspended solids are also separated to prevent escape of solids from the reactor.

Cogeneration Power Plant

Total wastewater generation from power plant will be 500 Cum/day. The effluent generated

from the power plant will be treated and utilized as following.

Cooling tower blow down, DM plant regeneration and Boiler blow down will be neutralized and

after treatment it will be utilized for ash quenching, dust suppression and greenbelt

development.

Sanitary waste water will be treated in septic tank followed by soak pit. Hence there will not be

any adverse impact on environment due to the proposed activities.

Non Process Effluent Treatment & Disposal:

The boiler blow down and DM plant regeneration waste water will be treated in a neutralization

tank and after treatment it will be mixed with CT Blow down. All these treated effluent streams

will be stored in a Central Monitoring Basin (CMB). The treated effluent will be used for dust

suppression / ash conditioning and onland for irrigation within the premises after ensuring

compliance with CPCB / SPCB standards. The scrubbed water from CO2 Scrubber will be

consumed in the Fermentation section. The effluent will be used for greenbelt development

within the plant premises after ensuring the compliance with CPCB/SPCB standards.

Distillery

As per CPCB recommendations the spent wash quantity will be restricted to a maximum of 8

kl/kl of R.S. for Molasses by adopting continuous fermentation technology with yeast recycle.

The Maximum Spent wash input to Bio-methanation will be 480 KL/day

TREATMENT SCHEME

Spent wash generated will be treated in three stages

1. Bio-methanation

2. Evaporation

3. Bio-composting

BIO-METHANATION

"CSTR" continuous flow stirred-tank reactor process will be adopted for Bio-methanation,

which is based on the concept of conversion of organic matter into biogas. The process of

conversion of organic matter into biogas occurs through a group of bacteria.

In 'CSTR' process, which is a high rate process, anaerobic digestion takes place in the

Mesophillic range of temperature, the pH inside the reactor is usually kept around 7.2 while

proper ratio of volatile acid and alkalinity is maintained.

The following three stages are involved in the process of anaerobic digestion

1. Hydrolysis: In the process of hydrolysis the complex molecular compounds i.e. polymers

are converted into the simple molecular form i.e. monomers.

2. Acidogenesis: The monomers so formed at the end of hydrolysis process are converted

into volatile fatty acids. Acetic acid forms the major portion of volatile fatty acids. The

process of conversion of monomers into acids is carried out by a group of anaerobic

bacteria known acid formers.

3. Methanogenesis: Acids produced at the end of Acidogenesis process are converted into

carbon dioxide and methane gases. The process of conversion of acid into gases is

carried out by group of anaerobic bacteria known as methane formers.

In CSTR process the bacteria responsible for digestion process are kept in suspension with

the help of Lateral as well as central mixers.

EVAPORATION PROCESS

Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion

by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration,

process. Evaporation process can be defined as one that starts with a liquid product and ends

up with a more concentrated liquid as the main product from the process.

In first evaporation stage,

Bio-methanated Spent wash will be subjected to heat through steam

Spent wash vaporized in first stage will give energy to second stage.

There will be total four falling film evaporator and one forced circulation evaporator.

These Evaporators will be in forward feed arrangement.

Vapours of Second evaporator will be fed to third effect Evaporator. Vapours of Third

evaporator will be fed to fourth effect Evaporator. Then, Vapours of fourth evaporator will

be fed to fifth effect Evaporator.

Falling film evaporators will be operated at very low temperature differences between the

heating media and the boiling liquid, and they also have very short product contact times,

typically just a few seconds per pass.

These characteristics make the falling film evaporator particularly suitable for spent wash

evaporation.

This is specifically designed Spent wash distributors for the proper distribution of Spent

wash in tubes. Specific design of the liquid distribution system achieve full and even

product wetting of the tubes. Because of the low liquid holding volume in this type of unit,

the falling film Evaporator can be started up quickly and changed to cleaning mode

easily.

Falling film evaporators are highly responsive to alterations of parameters such as

energy supply, vacuum, feed rate, concentrations, etc. it will be equipped with a well-

designed automatic control system therefore it can produce a very consistent

concentrated product.

BIO-COMPOSTING

FEATURES OF BIO COMPOSTING TECHNOLOGY

Zero discharge concept

Complete Destruction of BOD in effluent

Flies & odour free

High quality product

Dry baggable product, easy to handle and transport.

PROCESS OF BIO COMPOSTING

A Composting cycle takes 8 weeks to complete and involves the following activities.

1st week

1. Collection of raw material:

First week Filter Cake, Boiler Ash and organic residues compose one compost batch. They

are hauled from storage yard to the bioearth compost area, a level and well-drained land that

permit heavy equipment operations.

2. Formation of Windrows & Trimming

Using a pay loader the press mud is spread in piled windrows and trim to allow passage of

Aero tiller. Each windrow consists of 100-150 metric tons of press mud. Each windrow is of

1.5m width at bottom and 100m length.

2nd week

1. Aerating and mixing:

Make the first pans of the mixovator on windrows.

2. Inoculation of bioearth:

After the first aeration pass, the material will have achieved moderate mixing and ready

for application of acitobactor and Phosphorous soluble reagent at ½ kg per ton of

waste. This will accelerate composting stabilize temperature 65-750C and enhance

beneficial microbes.

3. Aerate the pile after inoculation and retrim.

3rd to 6th week

1. Maintenance of Moisture:

The Moisture of the pile is maintained to 50% to 60% heat is evolved during process,

this built up together with solar heat and other factor increases. Temperature resulting

to evaporation. Moisture drops to a level of about 30%to35%.

2. Application of Distillery effluent after Digesters:

Excessive/ inadequate moisture slows down composting exhibited by drop in

temperature from the trend established. Windrows are watered back to desired

moisture level using distillery effluent as moisturizing agent. The total volume

applicable each week is sprayed three times during the week.

3. Aeration:

Make one to two pass of the Mixovator after each effluent application and then retrim.

Mixovator grinds, blends, spreads, aerate and disperse the growing fungi for a uniform

and thorough decomposition of the windrow.

4. Inoculation with culture

During the 5th week, culture is again applied at 0.5 kg/ton in order to restimulate

microbial activity and to stop the development of odour.

5. Curing, Aging and Drying

7th week:

Effluent application is stopped at the end of the 6th week and the compost is allowed to cure

and age. Water is applied during the 7th week while mixing is continued twice in a week until

moisture stabilizes at 20%to 30%.

8th week:

Disposal of Bio earth to End –user Farms:

Transport the bio earth to end-user farm or a suitable storage in order to vacate the area

occupied by the compost and accommodate another batch Otherwise, a large bio-earth

composting area may be needed to process the annual production of waste.

sugar mill operations with enhanced energy efficiency measures and optimum usage of

Molasses and Bagasse. During season, the Co-gen Plant will be operated on bagasse

generated in the Plant and coal when necessary.

All excess available power will be exported to the grid. During off-season based on the

availability of Bagasse / biomass from nearby sugar mills power will be generated.

Further, the integrated Sugar & Co-gen projects will improve the overall profitability of TSL,

through its additional revenue generation. This will enable TSL to give higher dividend to

promoters & higher price per ton of cane to its cane growers. Also the project will help to

improve Telangana State‘s power situation.
