MOPICO ®Compact compression system for gas transport

MOPICO ®Gas pipeline compression systemsThe MOPICO ® is a unique state-of-the-art integrated motor-driven pipelinecompression system. The simple, compact and cost-effective designconcept results in a highly reliable and largely maintenance-free systemwith the highest efficiencies over the complete operating range.Design characteristicsThe MOPICO ® compression systemsare available in various frame sizes, determinedby the required motor rating.The product range can accommodateflow rates of between 190,000 Nm 3 /h to1,890,000 Nm 3 /h and pressure ratios ofapproximately 2.Basic design: the ultimate in conceptualsimplicity – single rotating element,two radial and one axial bearing,no couplings, no gear box, nolube oil, no shaft seals to atmosphere.Motor: high-frequency variable-speedinduction motor. The rotor shaft isextended on both sides with asingle, overhung impeller mounted oneach end.Bearings: the rotor shaft is suspendedby two radial magnetic bearings andpositioned by a single axial magneticbearing.Cooling: the motor and magneticbearings are cooled by process gas,bled after the first compression stageand subsequently recycled into thesuction system.Hermetically-sealed pressurizedsystem: dictated by the motor cooling,the complete system operates ata pressure approximately equal to thesystem intake pressure. The threepiecevertically-split outer casing isdesigned for operation at pressuresof up to 150 bar.Drive system: the motor is driven bya solid state, variable frequency drivesystem (VSDS), remotely located fromthe compressor building.Product rangeThe MOPICO ® is available with motorpowers ranging from approximately 3MW (4,000 HP) to 18 MW (24,000 HP)based on three motor frame sizes. Themotor and compressor componentsare standardized to maintain the externalgeometry of the units. This results instandardized dimensions. A wide selectionof impeller types with varyingwidths and diameters ensures optimalthermodynamic efficiencies.Principal featuresThe MOPICO ® is a hermetically-sealed,integrated electric motor-compressorsystem designed especially for gas pipelineapplications. The unique concept ofthe system results in the lowest capital,operating and maintenance costs.Main featuresHigh-frequency, squirrel-cage inductionmotor directly connected to twoseparate compression stages at eachend of the motor shaft. The motor iscooled by process gas at a pressureapproximately equal to the pipelinesuction pressure.Two separate compression stageswhich can be connected in bothseries and/or parallel, which togetherwith the motor speed variation providesthe widest possible operatingrange.The rotating assembly is a stiff shaftdesign with a margin greater than25 % to the first lateral bending mode.The hermetically-sealed design andthe elimination of oil systems resultin an environmentally neutral system,1 MOPICO ® compact compression system for gas transport

Key process data aretrended and recorded and can becalled up remotely through a standardcomputer link.231 Booster station withthree MOPICO ® unitsHigh-speed electric motor2 One of the three identicalMOPICO ® unitsStation designThe compactness and low weight of theMOPICO ® allow for simple and costeffectiveinstallations in functionalindustrial buildings. The use of magneticbearings virtually eliminates thetransmission of vibrations from the unit,resulting in substantially reduced foun-dation costs. Thanks to the magnetic bearings andthe thickness of the high-pressure motor casing, theMOPICO ® noise emission levels are extremely low. Formost applications, no additional noise attenuation isrequired.3 MOPICO ® in seriesoperation modeMOPICO ® compact compression system for gas transport2
