Title: REFRIGERATION CIRCUIT SYSTEM AND METHOD OF MAINTAINING A GAS SEAL OF A COMPRESSOR SYSTEM
Abstract:
A mixed refrigeration circuit system (102) for a gas liquefaction process comprises a heat exchange arrangement (104, 166, 168, 214), a compressor system (144, 146, 160, 166, 168, 174, 192), a drum (118, 192) and a fluid conduit network. The compressor system (144, 146, 160, 166, 168, 174, 192) is in fluid communication with the heat exchange arrangement (104, 166, 168, 214), the compressor system (144, 146, 160, 166, 168, 174, 192) comprising a gas seal system (150). The drum (118, 192) is in fluid communication with the heat exchange arrangement (104, 166 168, 214), the drum having a vapour outlet (120, 194). The fluid conduit network is arranged to connect the heat exchange arrangement (104, 166, 168, 214), the compressor system (144, 146, 160, 166, 168, 174, 192) and the drum (118, 192) in a circuit. The vapour outlet (120, 194) of the drum (118, 192) is operably coupled to the gas seal system.
