FIELD: compressor plants for compressing and cooling gases. SUBSTANCE: part of separated condensate which has been precooled is fed to suction branch pipe of flow section of compression stages; other part of condensate is fed to delivery branch pipe of compression stages and to gas coolers mounted between compression stages for wetting the cooling surface. Compressor plant is provided additionally with cooler for cooling the condensate; inlet of the cooler is connected with all condensate traps of gas coolers and its outlet is connected with suction and delivery branch pipes of each compression stages, as well as upper portion of condensate receiver. Lines feeding the condensate from condensate coolers to delivery pipes are connected with inter-tube space of gas coolers. EFFECT: enhance efficiency. 3 cl, 1 dwg
