Claim 0:
1. A system for recovering a process gas from a first volume at a first pressure to a second volume at a second pressure, the system comprising:
one or more regulation stages receiving the process gas from the first volume at the first pressure and configured to step down the first pressure to an intermediate pressure, each of the one or more regulation stages comprising a pressure control valve to step-down pressure of the process gas;
a gas scrubbing stage receiving the process gas from the one or more regulation stages and collecting liquid from the process gas;
one or more compression stages receiving the process gas from the gas scrubbing stage and configured to step up the intermediate pressure to a final pressure, each of the one or more compression stages comprising a compression cycle to step-up pressure and comprises a heat exchanger to cool the process gas thereafter; and
a discharge stage receiving the process gas from the one or more compression stages and configured to discharge the process gas at the final pressure to the second volume at the second pressure, the final pressure being equal to or greater than the second pressure,
wherein each of the one or more compression stages comprises:
a pressure safety valve disposed upstream or downstream of a scrubber and configured to release the process gas above a pressure threshold to a gas outlet, the pressure threshold for each of the one or more compression stages increasing from one of the compression cycles to the next.
