2.0 INTRODUCTION
2.1 IMPORTANCE OF ENERGY CONSERVATION & ITS BACKGROUND
Energy is one of the most coveted inputs in the development of any society. With the
accelerated growth of the economy the demand for energy is increasing exponentially. On the
supply side the stock of the conventional energy resources like fossil fuel are limited and
rapidly depleting. India gradually becoming dependent on external sources of energy thereby a
considerable part of the GDP is exhausted for procurement of energy.
One of the easier available options for survival is energy conservation through energy
efficiency improvement; thereby reduction of energy consumption and cost thereof through
strategic energy management concept and mechanism.
Energy conservation is a worldwide objective. The energy policy of the Government of India
also calls for conservation of energy. With the enactment of ‘Energy Conservation Act-2001’,
amongst others has emphasized upon the power of the appropriate Govt. to enforce efficient
use of energy and its conservation.
The management of OIL has adopted the energy system study and implements solutions
thereof with the objective to optimal utilization and output of available energy consuming
systems and to conserve energy.
In view of energy efficiency improvement and cost reduction program for long-term business
solution the management of OIL sought the services of PCRA for energy system study on Gas
Compressors, air compressors and Lighting systems at their plant (GCS-2)at Moran in Assam.
PCRA has studied the energy systems of the plants accordingly with the help of OIL
representatives. During the study, the energy audit team has mapped present status of
electrical power and energy systems at the plant premises, identified, major energy loss areas
etc. The study has identified potential scope for improvement and energy efficiency
improvement in major energy consuming systems. It also recommends cost effective and fast
pay back solutions for energy cost control.
2.2 COMPANY PROFILE
The story of Oil India Limited (OIL) traces and symbolizes the development and growth of the
Indian petroleum industry. From the discovery of crude oil in the far east of India at Digboi,
Assam in 1889 to its present status as a fully integrated upstream petroleum company, OIL has
come far, crossing many milestones.

On February 18, 1959, Oil India Private Limited was incorporated to expand and develop the
newly discovered oil fields of Naharkatiya and Moran in the Indian North East. In 1961, it
became a joint venture company between the Indian Government and Burmah Oil Company
Limited, UK.
In 1981, OIL became a wholly-owned Government of India enterprise. Today, OIL is a premier
Indian National Oil Company engaged in the business of exploration, development and
production of crude oil and natural gas, transportation of crude oil and production of LPG. OIL
also provides various E&P related services and holds 26% equity in Numaligarh Refinery
Limited.
The Authorized share capital of the Company is Rs. 2000 Crores. The Issued, Subscribed and
Paid share capital of the company is Rs. 601.14 Crores. At present, The Government of India,
the Promoter of the Company is holding 78.43% of the total Issued & Paid-up Capital of the
Company. The balance 21.57% of the Equity capital is held by others.
OIL has over 1 lakh sq km of PEL/ML areas for its exploration and production activities; most of
it is in the Indian North East, which accounts for its entire crude oil production and majority of
gas production. Rajasthan is the other producing area of OIL, contributing 10 per cent of its
total gas production.
Additionally, OIL’s exploration activities are spread over onshore areas of KG Basin, Mahanadi
Basin, Cauvery Basin, Andaman Basin and Gujarat-Kutch Basin etc. OIL also has participating
interest in NELP exploration blocks in Mahanadi Offshore, Mumbai Deepwater, Krishna

Air compressors are connected to common receivers. Air is supplied at 14 kg/ cm2 for cranking
operation of the gas engines of gas compressors during start-up. Air @ 6 kg/cm2 is required for the
pneumatic control of the gas engine valves & circuit.
Pneumatic air taken from the air receiver passes through a pressure reducing device and air dryer and
supplied to pneumatic systems @ 6 kg/cm2
at the gas compressor panel only as the pneumatic control
valves in the unit are controlled by the NG after reducing the pressure.
Air Pressure of around 12 kg/cm2 is only required at the time of start-up of the gas engines and once
the engines are started then maintaining 14 kg/cm2 header pressure is not required. Continuous air
pressure is only required for the pneumatic control valves & circuit of the gas engines and that too at 6
kg/cm2 pressure.
In present condition the air is maintained from 14 kg/cm2 at any point of time. The unloading of the air
compressor is set at 14kg/cm2 and the loading set is at 10 kg/cm
2. But, in eight hours of our stay in the
air receiver area, it never got unloaded and it was told to us that the compressor always runs without
unloading. This means the line leak is almost 90%, approx 10% air is being used in the compressor
panel.
Hence in the above condition it is clear that although the air pressure requirement of 14 kg/cm2 is only
required during starting of the Gas engines but still the pressure is maintained at 14 kg/cm2 throughout
the day in order to start any engine when sudden requirement is there.
The performance of the Air Compressors (FAD Test) could not be carried out as the compressors could
not be isolated due to operational inconvenience.
It should be noted that more power is required to compress air at higher pressure compared to lower
pressure i.e, energy required to compress air from 6 to 14 kg/cm2 is much higher compared to
pressurizing air from 3 to 6 kg/cm2.

RECOMMENDATIONS:
At GCS, compressed air is used for two purposes:
1. To start Gas compressor engines (pressure requirement 14 kg/cm2).
2. To drive pneumatic instruments (pressure requirement 6 kg/cm2).
Pressure requirement for both the works are different as mentioned above.
1. It is recommended to maintain different air receivers for 14 kg/cm2 and 6 kg/cm2 line pressure.
Also one of the compressors should be dedicated to 14 kg/cm2 and the other one for 6 kg/cm2
line so that total running time of both the air compressors would reduce in a day.
To have redundancy in operation of the air compressors, one bypass line can be connected
from both the air receivers with a valve in-between so that whenever one compressor is under
shutdown then the other compressor can be compensated.
With a rough estimate min. of 25% of energy can be saved with this kind of arrangement.

Simple Payback period = To be estimated on the basis of the cost for line excavation and
replacement.
2. It is advised to arrange to carry out leak test at the air line flanges, instrument air reducing
points and copper tubing connectors. This will allow the use of 20 HP compressor to run and
cutoff.
Savings: Power savings in one year= (21.33 - 11.91)x 8760hrs = 82519.2 Kw = Rs. 375462

5.4 REPLACEMENT OF MOTOR DRIVEN COMPRESSORS WITH GAS ENGINE DRIVEN TO CONSERVE
POWER
It was informed to us by OIL personnel that though presently there is surplus power
avaliable at Moran Power Station but in future due to commissioning of new motors
replacing Crude Driven Engines in the Crude oil pumping Station, the power may not be
available for running gas engines in the Gas compression station.
Therefore, following calculation is given to calculate the cost of replacement of
Compressor Motors with New Gas engines.
By matching the RPM of the Gas compressors and BHP of the present Electric Motors, it is
found that Waukesha Dresser F 3521GL is suitable for replacing motors of GL-1,GL-2,LPB-1
and LPB-2.
As per the data sheet the compressor is having Compression Ration of 10.5:1, RPM of 1000
and BHP of 615.
The fuel consumption at full load is 110.6 m3/hr. as the load curve the fuel consuption at
60% load as per design will be 98 m3/hr
Cost of purchasing the Gas Engine is $1,65000 = 1,65000 X 55= Rs. 90075000/-
The cost of running one Gas engine is 98 X 24X365 = 858480 X Rs.8.83 (Cost of NG) = Rs.
7580383.00
Present average equivalent power consumption of running one motor is 260.7 kwh
Cost of running of one motor is 260.7 X 24 X365 X Rs.4.55 = Rs. 10390980/-
Report on Energy Audit of OIL installation at GCS-2, Moran, Assam, India
---------------------------------------------------------------------------------------------------------------
Energy Audit by PCRA, Eastern Region Page 20 of 27
Savings per year = Rs. 2810597
Payback= 90075000/2810597 = 32 years.
Therefore, it is economically not feasible to replace the motors with gas engines but in
case of non avaliability of power, gas engines can be procured.

6.2 RECOMMENDATIONS AND PAYBACK ANALYSIS:
1. Replace all the conventional 36 watt FTL tube light with energy efficient T5 (28 watt).
2. To replace all 160W MLL lights with 150 W MH lights in the shed, this will improve the lights in the
shed which is presently very poor with respect to OISD standard.
