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.
Abstract
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 pro-posed.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.
