PROCESS OF AND PLANT FOR INCREASING GAS TEMPERATURE AT ANY COMPRESSION STAGE OF COMPRESSOR Russian patent published in 2008 - IPC F25B1/00 F04B39/16 

FIELD: compressor building.

SUBSTANCE: invention can be used in automobile gas filling compressor stations with adsorption drying of gas. According to invention, delivered to suction in compression stage is heated by contactless heat exchange with gas of the same stage and then is compressed in the stage getting higher temperature gas. Plant has compressor with compression stage, line to deliver gas into said stage, suction and delivery lines of said stage, gas drying and adsorbent regeneration unit including absorbers delivery line of compression stage is connected with corresponding absorber by regeneration line. Device for contactless heat exchange is connected by one side at input with stage delivery line, and at output, with stage suction line, and by other side is connected by input with stage delivery line and at output, with adsorbent regeneration line by means of additional lines. First additional line is provided with shutoff and control devices before contactless heat exchange device, and delivery line is provided with shutoff-and-control devices before input of regeneration line.

EFFECT: provision of process at which delivery temperature rise is provided to required value in any stage, any season of year in any compressors.
