- 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.
