GAS-LIQUID CO-CURRENT CONTACTOR SYSTEM AND PROCESS FOR CLEANING SOUR GAS

摘要

A co-current contacting system for removing impurities from a gas stream is described herein. The co-current contacting system includes a co-current contactor configured to co-currently flow a gas stream including impurities and a liquid stream through the co-current contactor. The co-current contactor is also configured to incorporate liquid droplets formed from the liquid stream into the gas stream, such that the impurities from the gas stream are absorbed by the liquid droplets. The co-current contacting system also includes a separator configured to remove the gas stream from the liquid droplets including the impurities, generating a purified gas stream and a rich liquid stream. The co-current contacting system is configured to recycle the rich liquid stream for reuse as a portion of the liquid stream flowing into the co-current contactor.
