Abstract (en)
[origin: EP2444759A2] The method involves compressing working gas in a compression station (2) according to compression stages that utilize lubricated screw compressors (EC1, EC2) and centrifugal compressor (EC3). The compressed gas is cooled in a cold box (3) until a determined cold temperature. The centrifugal compressor belonging to another compression station (12) of refrigerator or liquefier (11) distinct from another refrigerator or liquefier (1) is selectively used, where the former refrigerator or liquefier utilizes working fluid having same nature as that of the latter refrigerator or liquefier. An independent claim is also included for an installation comprising distinct refrigerators or liquefiers to provide frigories to distinct consumer applications.
