CONTROL METHOD AND DEVICE FOR COOLING AGENT COMPRESSOR, AND THEIR USE IN HYDROCARBON FLOW COOLING METHOD Russian patent published in 2013 - IPC F25B1/53 F25J1/02 F04D27/02 

FIELD: machine building.

SUBSTANCE: control method of one or more compressors (12) used for compression of one or more gas flows (10) at normal operating temperature. At least one cooling agent compressor (12) is equipped with steam recirculation pipeline (30). Initial flow (10a) for the compressor is obtained as a result of combination of recirculation steam flow (30) from steam recirculation pipeline (30) and at least partially evaporated cooling agent flow (8). Initial flow (10a) for the compressor is passed through inlet separator (11) to obtain gas flow (10) for the compressor, which is passed through cooling agent compressor(s) (12). Inlet temperature T1 of gas flow (10) is determined for the compressor, and cooling agent flow cooling is controlled depending on temperature T1 to obtain gas flow (10) for the compressor at normal operating temperature at least of one cooling agent compressor (12).

EFFECT: use of the invention will allow independent control of temperature of the initial flow entering the compressor.
