摘　　要：利用流程模拟软件Aspen plus对乙炔法制备制冷剂HFC-152a的精馏装置进行了模拟计算与优化。在所建模型基础上,重点研究了进料位置与回流比对精馏塔采出产品的质量分数的影响。通过模拟与优化,得到最佳操作条件为高沸塔进料位置为34块板、回流比2,兼顾了塔的低能耗与提高产品质量。Process simulation software Aspen plus is used to simulate and optimize the distillation columns of1,1- difluoroethane（ HFC- 152a） based on acetylene. Based on the model,the feed stage and reflux ratio are mainly researched on how to affect the purity of the product from the top of the distillation columns in this paper.The obtained optimized operation parameters of high boiling point column are the 34 th feed stage and reflux ratio 2,giving consideration to the low energy consumption of the column and improving the quality of products.
