Alfa Laval MBUX 214 centrifuge is used for recovery of micro-organisms and cell debris in high density fermentations.

ApplicationThe solids discharging nozzle centrifuge type MBUX 214 is designed specially for separation of microorganisms from high density fermentation broths.

The centrifuge is used to separate, wash and concentrate microorganisms with normal particle size in the range 1 - 5 μm. The content of the suspended solids in the feed is normally in the range 2 - 7,5% DS.

Design featuresWith the patented Alfa Laval self regulating vortex nozzles the concentration of discharged solids phase can be kept at a high and even level irrespective of fluctuations in the feed flow or feed concentration. The centrifuge can thus be operated closer to the clogging point without increasing the risk of clog-ging.

The disc inlet ensures a lenient acceleration of shear sensitive microorganisms.

The light and heavy phases are both discharged under pres-sure which prevents foaming and simplifies installation by eliminating pump systems and improves hygiene.

Solids pockets in the bowl guide the solids to the concentrate tubes, preventing accumulation of firmly packed solids and making separation and CIP easier and more effective.

Frame hood and solids receptacles are jacketed for circula-tion of cooling water, which also reduce the noise level. Frame hood and solids receptables are fitted with spray nozzles for washing the outside of the bowl.

The Control Panel (optional) handles the control and supervi-sion of the MBUX 214 centrifuge including a cleaning-in-place (CIP) mode.

Nozzle separator for hygienic, pressurised recovery of microorganisms

MBUX 420

The Alfa Laval centrifuges for recovery of yeast and other microorganisms take advantage of the fact that the slurry of concentrated solids is pseudo-plastic and flows easily in the bowl against the centrifugal force. This means that the recov-ered solids can be obtained with a low demand on energy in a closed system under pressure. Therefore, the hygienic conditions are very good, further improved by a full-speed CIP procedure. The MBUX 420 has a bowl body in Super Duplex stainless steel, for added strength and corrosion resistance.

Applications The solids discharging nozzle centrifuge type MBUX 420 is designed for separation of micro-organisms from fermentation broths, e.g. in chemical and pharmaceutical industries, and for yeast extract production.

Special features With the patented Alfa Laval self regulating vortex nozzles the concentration of discharged solids phase can be kept at a high and even level irrespective of fluctuations in the feed flow or feed concentration. The centrifuge can thus be operated closer to the clogging point without increasing the risk of clog-ging. The light and heavy phase are both discharged under pressure which prevents foaming and simplifies installation by eliminating pump systems and improves the hygiene. Solids pockets in the bowl guide the solids to the concentrate tubes, preventing accumulation of firmly packed solids and making separation and Cleaning In Place (CIP) easier and more effec-tive. Automated CIP at full speed. Frame hood and solids receptacle are jacketed for circulation of cooling water, which also reduce the noise level. Frame hood is fitted with a spray nozzle for washing the outside of the bowl. A rotating liquid seal below the bowl seals off the bowl casing from the drive system.

MBUX 420

Standard design The MBUX 420 has all liquid-wetted parts in high-grade stain-less steel and rubber sealings food approved EPDM or nitrile rubber. Connections for inlet, centrifugate and concentrate are hygienic screw couplings. The separator is equipped with speed and vibration sensors. The anchoring feet are equipped with vibration dampers. The MBUX 420 is driven via a belt by a flange-mounted controlled torque motor. The separator is delivered with the motor pre-mounted at the factory so there is no need for alignment on site.

Operating principlesSeparation takes place in the disc type bowl which is equipped with concentrate tubes and vortex nozzles. The heavy solids phase is moved outwards by the centrifugal force in to the solids pockets at the bowl periphery and from there through concentrate tubes (1) and internal vortex noz-zles (2) into the paring tube chamber, where the concentrate is skimmed off by the paring tube (3) and discharged under pressure. The clarified liquid phase is displaced towards to the centre through the disc stack (4). This phase is then dis-charged under pressure by means of a built in paring disc (5). The bowl can be opened intermittently during production and/or the cleaning cycle for ejections of solids while the machine continues to run at full speed. The hydraulic (6) controlled valve slide (7) under the bowl bottom opens the discharge valves (8) momentarily, permitting the ejections of solids.

ApplicationThe MIB 303 separation system is designed for centrifugalseparation of sludge and water from mineral oil. The separator is designed for oils with a maximum density of 920 kg/m3 at 15°C. The maximum separation temperature for gas oil and marine diesel oil is +40°C, and for lubricating oil +70°C, since this is the max. separation temperature for the separator.

Mineral oilThe MIB 303 separator in a cleaning system for distillate andmarine diesel oil should be operated as a purifier. For cleaningof lubricating oil, MIB 303 purifier or clarifier can be used.

ConceptThe MIB 303 separator features a special design concept for solid-bowl separators. Advanced manufacturing, design and drive technologies have contributed to a separator more compact and lightweight than conventional solid-bowl models .

Features• No lock ring. Requires only small mechanical force on

opening/assembling of the bowl.• The design allows the bowl wall to be taken out and

cleaned with the disc stack still in place.• Lightweight materials in bowl and discs.• Direct drive with motor speed controlled by a frequency

converter eliminates gears or belts.• Requires no lubrication.• The cleaned oil is discharged under pressure, due to the

built-in paring disc pump.• Frequency converter with built-in voltage protector.

Benefits• Easy to install, operate and maintain. No special training

required.• Small dimensions allow installation in narrow spaces.• Removal of solid impurities extends intervals between filter

replacements, which saves filter costs and reduces filterdisposal handling.

• Removal of water from mineral oil improves the reliabilityof the oil system . It also reduces the risk of bacterial growthin tanks that could clog the filters.

• Electronics protected from voltage variations.

Throughput capacityThe MIB 303 separator has a throughput capacity of max. 760 litres per hour of diesel/gas oil and max. 460 litres per hour of steam turbine lube oil.

Available modelsThe MIB 303 separator is available as a purifier or a clarifier in stand-alone and module versions. There is also a choice between 230 V AC and 110 V AC. In the module version the ancillary equipment mentioned above is built together with the separator to form a compact unit.

Ancillary equipmentNecessary for operation are: feed pump, collecting tank with water seal alarm, strainer, valves and fittings.

Optional equipmentThe MIB 303 module is also available in the mobile version on the trolley.

Power consumption700 W ±10%.

Weight of module 68 kg (81 kg for the trolley version).

Purifier operation Separation takes place in the rotating solid-wall bowl. The uncleaned oil is fed into the bowl where the cen-trifugal force makes water and solid particles move out towards the periphery of the bowl, while the clean oil flows inwards.

To establish a water seal during start-up of the separator, water is added to the bowl before the oil feed is started. The water collects in the water seal which drains into the water channel below the bowl.

The solids accumulate on the bowl wall and are removed periodically by hand.

The cleaned oil flows towards the centre of the bowl and up to the paring disc. Since the oil is rotating , the stationary paring disc acts as a pump which forces the oil out through the outlet under pressure.

Clarifier operation In clarifier mode the oil normally does not contain any free water. The separation principle is similar to that of the purifier, although there is no water seal and no water outlet in the bowl and the water handling capacity is limited.

Technical documentation Complete information and documentation is provided in the instruction book accompanying each MIB 303 separator.

After sales support Replacement part kits for preventive maintenance at one and two years intervals are available.

Alfa Laval MIB 503 ModuleA compact separator module for marine & diesel applications

Introduction

In marine and diesel industry, customers struggle with low-quality fuels that have high content in particles and water.Operating on such fuels reduces the efficiency and the lifetimeof the engine while increases the risk of repair costs.

The MIB 503 Module is a complete separation solution fromAlfa Laval that improves the reliability of the oil system andprotects the main engine from serious wear and damages.

Application

• Distillate oil• Marine diesel oil• Lubricating oil

Benefits

• Easy to install and start up• Easy to operate and maintain• High separation efficiency• Robust and reliable design• Small footprint• Low power consumption

Design

The module is available in a gas oil and a lube oilconfiguration.

The gas oil configuration consists of the separator, the controlcabinet, the pump, the flexible hoses and the alarm sensors.All of the components are mounted in an optimally designedframe that can fit even the smallest engine rooms.

The MIB 503 separator consists of a solids-retaining bowlwhich can operate both as a purifier and a clarifier. Its uniquedrive technology is based on an electric motor mounteddirectly to the bowl, controlled by a frequency converterlocated in the control cabinet.

The pump installed on the module is a positive displacementpump with constant flow and is connected to the separatorthrough flexible hoses.

To secure the correct operation of the separator, a pressuresensor and a level sensor are installed on the module. Allfunctions and alarms are being handled from the controlcabinet which has been designed for simplicity and ease ofuse.

In lube oil configuration, the oil must reach the righttemperature before the separation process starts. Toaccomplish that, a heater, a three way valve and atemperature sensor are included in the module.

Scope of supply

• MIB 503 Separator• Pump• Flexible hoses• Control cabinet• Sensors• Frame• Three way valve (only for lube oil)• Heater (only for lube oil)

Options

• Wheel set• Drip tray• Emergency stop box• Trolley (only for gas oil)

Working principle

In gas oil application, the fuel oil is being transferred directlyfrom the pump to the separator. In lube oil application, aheater and a three way valve are installed between the pumpand the separator. The three way valve is being used to runthe oil on recirculation between the sump and the heater untilthe correct separation temperature is reached.

The separator starts up. When the separator reaches fullspeed, water is added to establish the appropriate water seal(applicable only for purifier setup). Subsequently, the pumpstarts up and oil is fed to the separator.

The separation process takes place within the bowl. Due tothe centrifugal forces, oil, water and particles are beingseparated based on their specific gravity. The heavy phases,water and particles, are moving to the periphery of the bowlwhile the light phase, oil, is moving towards the center of thebowl.

Water is being drained automatically to the collecting tank ofthe module. The separated particles need to be cleanedperiodically by hand. The clean oil is being pumped by aparing disc out of the separator and from there to the dailyservice fuel tank or the lube oil sump.

A pressure sensor is installed in the oil outlet after theseparator. The pressure sensor triggers an alarm duringseparation if the water seal interface is lost.

A level sensor is installed on the collecting tank of the module.The level sensor triggers an alarm if the separator overflows.

In lube oil configuration, a temperature sensor is installedbefore the separator. The sensor triggers an alarm when lubeoil temperature drops below 60°C.

All the sensors are connected to the pump which will stopautomatically if there is an alarm. In that case, the crew isinformed by the alarm lamp in the control cabinet of themodule.

Nozzle centrifuge

CH-38 GOF Separator

Alfa Laval separators for the starch industry are available in many different sizes and configurations, each one designed and adapted for dealing with the widely varying separation tasks required. The Merco CH-38 GOF is a dedicated starch centrifuge, designed for several applications in the maize wet milling process.

ApplicationsThe CH-38 GOF is a nozzle centrifuge designed for continu-ous discharge of solids. It is used for classification of solids according to size, dewatering and washing of solids, and for clarification of liquids containing relatively high concentrations of solids. The machine is Alfa Laval’s largest nozzle centrifuge for the maize starch industry. It is related to the widely used CH-36 but has a higher capacity and a larger bowl. It has a lower power consumption and is easier to assemble and disassem-ble. The CH-38 GOF is used for processes that include primary separation, gluten thickening, millstream thickening and mid-dling separation. Other common applications include wash-ing and concentration of solids in the production of industrial minerals and chemicals.

Standard designThe centrifuge is equipped with sensors for monitoring bowl speed, vibration, temperature and oil pressure. Thirty periph-eral nozzles are directed at a small angle to the tangent in order to recover energy from the material being discharged.

Special featuresThe CH-38 employs a special recirculation system that provides highly efficient separation. Solids can be recircu-lated to the nozzles at the same time as wash water is being recirculated. Working with the underflow draw-off valve, the return flow system provides a unique means of controlling the separation process. It allows the operator to control and optimise the separation process – by determining how much underflow is to be removed, how much is to be recycled back to the rotor and how much wash water is to be added. This makes it possible to use nozzles with a large diameter, which act as buffers to even out variations in feed concentration and to prevent blockages. The machine thus becomes more versatile, and can be easily adapted to changes in procedure.

Merco CH-38 GOF with motor

The machine also features a built-in hydraulic hoist that elimi-nates the need for an external lifting device, and thus reduces the downtime required to service the centrifuge.

Basic equipmentThe centrifuge is equipped with a motor, a self-cleaning strainer for the feed, speed and vibration sensors, oil tempera-ture sensors for the spindle bearings and the motor winding, a hydraulic power unit for the lifting hoist, a set of special tools and a standard set of spares.

OptionsControl-torque motors of four different power ratings are avail-able. Frequency drive is also possible. The centrifuge bowl can be configured in classifier (PS) or clarifier (GT, MST, and CL) execution, with different disc spacings. A double underflow outlet is available for the MST version.

Operating principlesThe feed, consisting of both liquid and solids, is led into the rotating centrifuge bowl from the top via a stationary inlet (1). It is then accelerated in a distributor (2), before entering the disc stack (3). The actual separation process takes place between the discs, with the liquid phase moving through the disc stack towards the centre of the bowl. When it has reached the centre, it is then discharged over a power ring (4). The solids, which are heavier, collect at the periphery of the bowl, and are then continuously discharged through the nozzles (5). Part of the concentrated solids discharged through these noz-zles can be recirculated into the bowl periphery through the recirculation tubes (6), via the recirculation chamber (7). The wash water used to free solubles and other impurities from the solids can also be recirculated to the periphery of the bowl the same way. The bowl is mounted on a vertical spindle (8) that is driven via belts by a vertically mounted motor.

System working principleSeparation takes place in a solids-retaining, also known as a solid-wall,bowl that can be arranged for purifica-tion or clarification (optional). In bothcases the contaminated oil is fed to theseparator by a feed pump through theoil inlet and is separated by centrifugalforce into its various phases. The heavi-est phase, sludge, is forced to anddeposited at the periphery of the bowl.Separated sludge is collected in thespace at the periphery of the bowl andremoved periodically by hand using thestainless steel sludge basket. The cleanoil is continuously discharged by thebuilt-in paring disc pump. Water leavesthe bowl via an open outlet.

When operated in purifier mode, agravity disc must be fitted to obtain thecorrect interface position (the boundarybetween the separated oil and thewater seal) in the separator bowl. In theoptional clarifier mode, a clarifier disc isfitted instead of a gravity disc.

A MAWA-40 water seal alarm is avail-able as optional equipment to monitorthe pressure in the clean oil outlet. Thecontrol unit will shut off the oil feed tothe separator in case a pressure drop is detected and give an audible andvisible alarm.

InstallationThe MMB separation system isdesigned for installation as a completesystem. The schematic layout in thefigure below shows a typical installationof an MMB separator. Contaminatedfuel or oil is supplied by the feed pumpfrom the oil tank to the separator bowlfor continuous cleaning.

After separation, the cleaned oil is dis-charged by a built-in paring disc pump.

The complete system includes MAWAwater seal alarm, starter, heater, valves,piping and other essential ancillaryequipment.

Alfa Laval MIB 503A compact solid bowl separator for marine & diesel applications

Introduction

MIB 503 is one of the smallest separators of Alfa Laval’s solidbowl series. This product has been an upgrade of itspredecessor, MIB 303, and has been developed to fulfill allrequirements of the marine and diesel industry.

Application

This product has been designed for the removal of particlesand water from distillate, marine diesel and lubricating oils.Removal of water and particles from mineral oil improves thereliability of the oil system. It also prevents serious wear anddamages to the main engine.

Benefits

• Easy to install and start up• Easy to operate and maintain• High separation efficiency• Robust and reliable design• Lightweight materials• Small footprint

Design

The separator consists of the frame housing, the separatorbowl, the inlet and outlet device as well as the electric motor.

The frame housing is the part where the electric motor andthe bowl are fitted. The motor can easily be accessed andinspected from a hatch. The hatch is located on the front partof the housing. The complete frame is sitting on rubberdampers which absorb all vibrations during operation.

The separator consists of a solids-retaining bowl which,depending on the application, can be used both as purifier orclarifier.

The MIB 503 is one extremely lightweight design. The outerparts of the bowl are manufactured in surface-coatedaluminium and most of the inner parts i.e. the disc stack, thebottom disc and the inlet cone are manufactured in high-grade polymer composite.

The unique drive technology is based on an electric motormounted directly to the bowl compared to conventionaldesign of gear and belt systems.

Scope of supply

• Frame housing• Separator bowl• Inlet & outlet device• Electric motor, direct driven• Set of plates• Documentation

Options

• Bowl conversion kit• Service kits• Set of tools

Working principle

The purifier operation takes place in the rotating solid-wallbowl. When the bowl is set as a purifier the uncleaned oil isfed into the bowl where the centrifugal force makes water andsolid particles move out towards the periphery of the bowl,while the clean oil flows inwards.

To establish a water seal during start-up of the separator,water is added to the bowl before the oil feed is started. The

water collects in the water seal which drains into the waterchannel below the bowl.

The solids accumulate on the bowl wall and are removedperiodically by hand. The cleaned oil flows towards the centreof the bowl and up to the paring disc. Since the oil is rotating,the stationary paring disc acts as a pump which forces theoil out through the outlet under pressure.

During the clarifier operation, the oil normally does not containany free water. The separation principle is similar to thepurifier, however there is no water seal, no water outlet andthe water handling capacity is limited.

Alfa Laval Oil Cleaning Module

OCM cleaning solutions for mineral oils

Clean oil is crucial for the safe, reliable and economicaloperation of virtually all kinds of equipment that uses oils foreither lubrication or hydraulic systems. Clean oil reduces wearand corrosion on all equipment installed downstream, thushelping avoid breakdowns and cutting back on downtimethroughout a plant or installation.

The Alfa Laval Oil Cleaning Module (OCM) provides rapid,effective separation of the oil, water and sludge componentsin contaminated mineral lubricating and hydraulic oils – all atthe same time.

The benefits include lower operating costs due to reduced oilconsumption, lower disposal costs and improvements in bothproduct quality and the working environment.

Easy to operate oil purificationThe Alfa Laval Oil Cleaning Module is a modularized systemwith all the component systems fully integrated, ensuringeasy operation while engaged in oil cleaning duties. At theheart of this compact, easy-to-use equipment is an AlfaLaval disc stack centrifuge of supreme efficiency.

Alfa Laval Oil Cleaning Modules are available with all compo-nents and systems pre-configured on a skid, for easy, rapidinstallation and ready for immediate use. They ensure theeffective removal of particles and water in the oil. If an emer-gency arises, even a high level of water contaminants can beremoved.

An OCM provides continuous purification of lubricating andhydraulic oils while the equipment in which they are used is inoperation. If required, the OCM can continue operating whilethe primary equipment is at a standstill.

The impact of contaminants in oilContaminants in lubricating and hydraulic oils have seriouseffects on system performance, operating costs and durability.For example, the presence of solid particles:• abrades metal surfaces• increases friction• clogs filters

Similarly, if water is present in the oil, this:• causes corrosion• reacts with additives

• forms oil/water emulsions• causes significant deterioration in the performance of the oil.

Cleanliness countsOCM oil cleaning modules are specifically designed toremove contaminant particles, solid impurities and free waterfrom mineral lubricating and hydraulic oils.This is important because clean, uncontaminated oil:

• extends the service life of all kinds of equipment by asmuch as 50%

• eliminates or reduces corrosion by removing free waterpresent in the oil

• ensures longer uptime operation, thus boosting productivity• results in significant reductions in machinery wear andbreakdowns

• cuts operating costs by reducing oil consumption• extends oil service life and therefore reduces replacementand disposal costs

• improves both product quality and the working environ-ment.

Oil cleaning capacities

InstallationThe oil cleaning module is normally installed in a by-passsystem, treating a specified percentage of the full flow ofcontaminated oil. Tank-to-tank installation is also possible.

The suction line from the lubricating or hydraulic oiltank/sump is installed in the lowest end of the tank, typically1/3 from the bottom. This ensures that any dirty oil present istreated promptly. The suction height should be as low aspossible in order to reduce or eliminate any pump cavitationeffect.

The oil return line is connected to the top of the oil tankopposite to the oil suction in order to ensure proper oil circu-lation during cleaning also when the turbine is out of opera-tion.
