Purpose of compressor unit is to compress recovered vapor from gas condensate. (1) Ariel JGN2 compressor is driven from 132kW UMEB motor with the possibility of automatic speed adjustment in the 750-1500 RPM domain. Three stages have been considered for the required pressure range and to maintain the discharge temperature under the acceptable limit. To minimize gas condensation the compressor is designed to perform with suction side gas temperature from +40°C to +45°C and up to +90°C on the second and third stage, as well on after cooler after third stage.
