There is disclosed a fluid separation system (16) for recovering a target fluid from a fluid mixture. The fluid recovery system (16) comprises an inlet (18) that is configured to receive the fluid mixture; a first compressor (24) for compressing the fluid mixture; a return line (26) that comprises a return line inlet (28) that is disposed downstream of the first compressor, such that, in use, 2024/023507 the fluid mixture is divided into a first portion (34) and a second portion (36); and a separation device (30) that is disposed downstream of the return line inlet (28). The return line (26) is configured to return the second portion (36) to upstream of the first compressor (22). In use, the first portion (34) is provided to the separation device (30) at a predetermined flow rate.
