APPARATUS AND PROCESS FOR THE PREVENTION OF ACID GAS EXCURSIONS

摘要

A system is provided for removing acid gases from gaseous streams which has particular application in reducing the incidence of sulfide and other acid gas excursions. The present invention addresses the disadvantages of prior absorption techniques by closely monitoring and maintaining a reaction zone temperature profile within a contactor to improve and control an exothermic reaction between acid gas components and an aqueous amine absorbent. A temperature profile is maintained by adjusting relative flow rates of the feed gas stream and aqueous amine in the process to reduce the incidence of excursions.
