膜分离法回收不凝气中乙醇/水蒸气的实验研究
Experimental Study on Recovery of Ethanol/water Vapor in Non-condensable Gas by Membrane Separation
摘要
Abstract
To Simulate the traditional fermentation, PTFE 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 concentration of ethanol in the non-condensable gas, the temperature and the downstream pressure influence on the 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, the temperature and the downstream pressure, the PTFE membrane' s permeation flux increases, the permeation flux conforms to Arrhenius equation. With regard to the PTFE membrane' s separation factor, it increases with the increase of the concentration of ethanol in gas, the temperature and decreases with the increase of the downstream pressure. ePTFE membrane which has better separation performance compared with PTFE membrane is beneficial to the separation of ethanol/water vapor.关键词
