共沸精馏分离乙醇-异丙醇
Separation of ethanol-isopropanol binary mixture by azeotropic distillation
摘要
Abstract
Azeotropic distillaition was used to separate ethanol-isopropanol mixture.According to principles of the selection of entrainer,1-hexene was selected for the separation.Aspen plus software was used to simulate continuous and batch azeotropic distillation flow process.In addition,the effectiveness of the selected entrainer was investigated by the batch azeotropic distillation experiment.The results showed that 1-hexene can be a successful entrainer to separate the ethanol-isopropanol mixture.The separation experiment of ethanol-isopropanol mixture by batch azeotropic distillation was carried out in a packed column with 30 theoretical plates.The reflux ratio was 25,and the 1-hexene and ethanol mass ratio was 4∶1.The product mass fraction of isopropanol reached 99.77%.关键词
