Isobaric pressure exchanger controls in amine gas processing

摘要

A system includes an amine gas processing controller that includes one or more tangible, non-transitory, machine-readable media collectively storing one or more sets of instructions and one or more processing devices configured to execute the one or more sets of instructions to operate a contactor to remove an acid gas from an untreated natural gas using an amine in a lean amine, output a treated natural gas, and output a rich amine stream, operate a regenerator to regenerate the amine in the rich amine stream, output the lean amine stream, and output the acid gas, transfer the rich amine stream from the contactor to the regenerator using an isobaric pressure exchanger (IPX), and transfer the lean amine stream from the regenerator to the contactor using the IPX.

1. A system, comprising:
an amine gas processing controller, comprising:
one or more tangible, non-transitory, machine-readable media collectively storing one or more sets of instructions; andone or more processing devices configured to execute the one or more sets of instructions to:
transfer a rich amine stream from a contactor to a regenerator using an isobaric pressure exchanger (IPX); andtransfer a lean amine stream from the regenerator to the contactor using the IPX;wherein the IPX transfers pressure energy from the rich amine stream to the lean amine stream.
