以黏胶纤维厂废气源中主要成分硫化氢为原料，采用低温甲醇洗工艺，硫化氢气体经分离提纯后与1，4-丁二醇反应，反应后产物经过分离及精制得到质量分数为99%的四氢噻吩产品。采用Aspen Plus软件对该工艺进行了全流程模拟，并对塔的塔板数、进料位置、回流比等工艺条件进行了优化，确定了最佳的工艺操作条件。同时通过对传统工艺改进和节能方案的优化设计可以节约电能37.7%及精馏操作成本14%。

Hydrogen sulfide,the main component in the waste gas source from viscose fiber factory,is used as raw material after purification through the rectisol process to react with 1,4-butanediol.The reactive products are separated and refined to obtain 99wt% tetrahydrothiophene.The whole process is simulated by means of Aspen Plus software,the process conditions such as the number of trays,feed position and reflux ratio are optimized,and the optimal process conditions are determined.In addition,electric energy can be saved by 37.7% and rectification operation cost can cut by 14% through improving the traditional technology and optimizing design of energy-saving scheme.
