摘要:
模拟传统发酵,将PTFE膜用于不凝气中乙醇/水蒸气的分离,研究了不凝气中乙醇浓度、进料温度、膜后真空度等操作条件对膜分离性能的影响,并对PTFE膜和ePTFE膜进行比较.结果表明,PTFE膜渗透通量随着气体中乙醇摩尔分数、进料温度、膜后真空度的增加而增加,温度与渗透通量符合Ar-rhenius方程.PTFE膜分离因子随气体中乙醇摩尔分数、进料温度的增加而增加,随膜后真空度的增加而减小.ePTFE膜相对于PTFE膜来说,具有较高的渗透通量,分离效果较好,有利于乙醇/水蒸气的分离.
Abstract:
To Simulate the traditional fermentation, P’i’FE membrane is applied in the separation of ethanol/water vapor in the non-condensable gas, This paper not only analyses the operating conditions such as the con-centration of ethanol in the non-condensable gas, the temperature and the downstream pressure infuence onthe membrane’ s separation performance , but also compares the PTFE membrane with the ePTFE membrane’s influence on separation . The result shows that with the increase of the concentration of ethanol in gas, thetemperature and the downstream pressure, the PTpE membrane’’s permeation flux increases, the permeationfux conforms to Arrhenius equation. With regard to the PTpE membrane’ s separation factor, it increases withthe inerease of the concentration of ethanol in gas, the temperature and decreases with the inerease of thedownstream pressure. ePTfE membrane which has better separation performance compared wih PTFE mem.brane is benefcial to the separation of ethanol/water vapor.
