ACID GAS REMOVAL WATER BALANCE INTELLIGENT CONTROL

Abstract: a process for acid gas removal includes feeding a sour natural gas to a contactor, feeding a lean amine adsorbent to the contactor, contacting the sour natural gas with the lean amine adsorbent to produce a sweet natural gas and a rich amine absorbent, recovering the sweet natural gas as an overheads from the contactor, recovering the rich amine absorbent as a bottoms from the contactor, feeding the rich amine absorbent to a regenerator, recovering desorbed acid gases as a regenerator overheads, producing the lean amine adsorbent recovered as a regenerator bottoms, and maintaining an amount of water circulating. a system for carrying out acid gas removal includes a contactor, a regenerator, a regenerator overhead temperature sensor, a feed gas flow rate sensor, and a make-up water feed system.
