Why is membrane separation sensitive to reverse pressure?
Thread Content
In cyclic hydrogen desulfurization membrane separation, why is there a concern regarding reverse pressure? What’s the reason?
Is the membrane directional? Sulfur cannot be removed in the reverse direction. Moreover, sulfur remains in the upper part; how can desulfurization be achieved under reverse pressure?
I’m not quite sure what you’re referring to, but we have desulfurization fiber membranes here; if they get clogged, steam backwashing can be used to clear them. Is that a desulfurization tower? I’m worried that the distribution panel at the top or the demister might be affected negatively
Reverse compression causes significant membrane loss; it easily damages the membrane. It should always be under positive pressure, and we use hollow fiber membranes. .
Based on the structural analysis of the membrane module, the membrane lacks strength assurance in the reverse direction. Therefore, opposing reverse compression is an important principle in membrane separation.

Reverse compression causes greater damage to the membrane
Thank you all! I’m asking what will happen if the outlet valve is opened first when membrane separation is put into operation, resulting in backpressure; and why?
