摘要
导出了计算渗透汽化平板膜的浓度剖面和温度剖面的微分方程组 ,结合实验得到的组分分通量关联式对千吨级渗透汽化苯脱水中试的膜面积和试验结果进行了验证 ,计算值和试验值符合良好 .模型的建立为万吨级渗透汽化苯脱水的工业设计和实施提供了参考 .
The differential equations which were used to calculate the concentration profile and the temperature profile of flat membranes in pervaporation process were derived. The computation results of dehydration of benzene with pilot pervaporation process were gotten by using these equations and showed good consistency with the experimental results. This model provided a reference for designing dehydration of benzene with pervaporation in industrial scale.
