FIELD: production of compressed gases. SUBSTANCE: plant is provided with receiver where ejector mixing chamber and separator are located. Mixing chamber of liquid-and-gas ejector is connected to separator on side of outlet. Receiver is partially filled with liquid working medium and its liquid outlet is connected to pump and compressed gas outlet is connected to compressed gas consumer. According to another version, ejector is provided with gas-and-liquid flow conversion chamber; ejector mixing chamber together with gas-and-liquid flow conversion chamber and separator are located in receiver. Gas-and-liquid flow conversion chamber is made in form of passage widening in stepwise pattern and its inlet is connected to outlet of ejector mixing chamber; its outlet is connected to separator. EFFECT: reduced power requirements for compression of gas; enhanced efficiency of plant. 13 cl, 2 dwg
