Abstract
A system includes an amine gas processing system that includes a contactor configured to remove an acid gas from an untreated natural gas using an amine in a lean amine stream, output a treated natural gas, and output a rich amine stream. The system also includes a regenerator configured to regenerate the amine in the rich amine stream, output the lean amine stream, and output the acid gas. The system also includes an isobaric pressure exchanger (IPX) configured to transfer the rich amine stream from the contactor to the regenerator and to transfer the lean amine stream from the regenerator to the contactor.
