摘要
用HYSYS2 2软件对甲醇和丙酮共沸物的萃取精馏过程进行了模拟计算,以水和单乙醇胺(MEA)作为溶剂,通过改变不同的条件:原料进料位置、溶剂比、回流比和溶剂进料温度,得出各自的最佳工艺条件;在模拟的最佳工艺条件下,对以水和单乙醇胺为溶剂萃取精馏分离甲醇和丙酮混合物进行了试验研究,试验结果和模拟计算相吻合,从而验证了模拟的可靠性;并对水和单乙醇胺两种溶剂的萃取精馏特点进行了比较,单乙醇胺的萃取精馏效果比水要好的多。
The simulation of extractive distillation for methanol-acetone binary azeotrope with extractive solvents of water and monoethanolamine(MEA) was made by the soft ware of HYSYS model version 2.2.The simulation under different conditions,the position of feed-stage,the ratio of extract solvent to feed,the reflux ratio and the temperature of extract solvents,was made for optimizing the operation parmeters.Through practical experiments and comparison of data between simulation and expriment,the reliability of simulation was testified.In addition,according to the comparison of the performance of extractive distillation between water and MEA,the extractive effect of MEA is much better than that of water.
