摘　　要：针对氯甲烷合成和副产盐酸减排中存在的问题,借助Aspen Plus软件对现有的工艺流程进行建模,搭建了单个CSTR反应釜模型,并在其基础上进行了模型修正、参数调优与灵敏度分析。提出了双釜反应器串联优化方案,通过优选进料配比、温度等参数,得到了双釜串联优化方案的较佳工艺:第1个釜维持160 ℃,第2个釜维持140 ℃;第1个釜进料的甲醇占总甲醇用量的75%;氯化氢与甲醇物质的量比为0.95。优化方案相较于原始工艺,氯化氢流率显著降低,是一种实现盐酸减排的可行方案。In order to solve the problems in the synthesis of chloromethane and the reduction of by-product hydrochloric acid emissions, Aspen Plus software was used to model the existing process flow, and a single CSTR reactor model was established. Based model modification, parameter optimization and sensitivity analysis were carried out. A dual-reactor in series was proposed. By optimizing feed ratio, temperature and others, the optimal process for the dual-reactor in series was obtained. The first reactor is maintained at 160 ℃, the second reactor at 140 ℃;the methanol fed into the first reactor accounts for 75% of the total methanol;the molar ratio of hydrogen chloride to methanol is 0.95. Compared with the original process, the optimized process significantly reduces the flow rate of hydrogen chloride, providing a feasible solution for reducing hydrochloric acid emissions.
