GAS SYSTEM FOR COMPRESSING A PROCESS GAS

摘要

The invention relates to a gas system (10) having a first compressor stage (20) for compressing a process gas (18), wherein the first compressor stage (20) comprises an intake side (20a) and a pressure side, and a seal gas (17) outside the first compressor stage (20) to prevent process gas (18) from escaping from leaks in the first processor stage (20), having at least one first line (12) for feeding back process gas (18) escaping from leaks in the gas system (10) situated downstream of the first compressor stage (20) to the intake side (20a) of the first compressor stage (20). Furthermore, the gas system (10) has at least one second line (13) for discharging a gas mixture escaping from the gas system (10) and consisting at least of process gas (18) and seal gas (17), wherein the at least one second line (13) is designed to feed back the escaping gas mixture to the intake side (20a) of the first compressor stage (20) and/or to a point in the gas system (10) upstream of the first compressor stage (20).
