摘　　要：在采用工业级DMC为原料的基础上,利用Aspen Plus软件的严格精馏模型和NRTL物性模块对于单塔常压精馏装置进行了模拟与优化,得到了单塔精馏的最优工艺参数。结果表明,通过单塔连续生产可将原料中的甲醇、水及重组分进行分离,从侧线得到了符合电池级DMC标准的产品,所得的电池级DMC产品回收率为76%。This study used industrial grade dimethyl carbonate(DMC)as raw material and the strict distillation model of Aspen Plus software and NRTL physical property module to simulate and optimize the single-tower atmospheric distillation unit.The optimal process parameters of single-tower distillation were obtained.The results show that methanol,water and heavy components in raw materials can be separated by continuous production in a single tower.The products meeting the battery grade DMC standard can be obtained from the side line,and the recovery rate of the battery grade DMC product obtained is 76%.
