FIELD: gas industry.
SUBSTANCE: disclosed is a device (200) for gas compression for use with gas flow (230). Device (200) for gas compression can comprise a number of compressors, one or more ejectors (270), condenser (350) located downstream of one or more ejectors (270), and source (205) of waste heat. Returned part (390) of gas flow (230) can be linked with one or more ejectors (270) through source (205) of waste heat. Each of one or more ejectors (270) includes inlet hole (280) communicated with returned part (390) of gas flow (230), and suction opening (300) communicated with gas flow (230).
EFFECT: invention is aimed at reduction of parasitic load and to increase net power generation of power plant.
