MCRC硫磺回收工艺研究与分析

摘要

MCRC硫磺回收工艺属低温吸附技术,过程气在硫露点以下进行反应,在低温反应段,2个反应器分别处于吸附与再生阶段.文中着重介绍MCRC硫磺回收工艺流程,并模拟给定硫磺产量的情况下以及改变酸气入口流量情况下整个流程的硫磺回收率,最高均为99.2%,且可指导现场操作人员,可监测一级反应器出口处H<,2>S与SO<,2>的摩尔比是否为2,来调节燃烧炉中空气流量.%MCRC (Mineral Chemical Resource Co. ) sulfur recovery process is a low-temperature adsorption technology, of which the process gas reacts at the dew point of suffur. In the low temperature reaction section, the two reactors react at the adsorption and regeneration phases respectively. The MCRC process flow was introduced and the sulfur recovery rate of whole flow under the given output of sulfur and acid gas inlet flow changing was simulated, with the highest value achieving 99.2％ in average, which can guide the field operator to monitor whether n(H:S) :n(SO2) is 2 at reactor outlet so as to adjust the furnace combustion air flow.
