Life assessment of membrane modules for methanol synthesis membrane recovery
Thread Content
What is the typical lifespan of membrane recovery membrane modules? I have noticed that, with the opening degrees of the air inlet valve and the non-permeate gas discharge valve in our membrane system remaining unchanged, the air intake volume to the membrane modules is significantly higher than it was a year ago. My humble guess is that the damage to the membrane modules has reduced the flow resistance; I hope fellow sailors can offer their guidance
Analyze the purity of the permeate gas, and also analyze the composition of the exhaust gas. Compare it with the original values; if there are no significant changes, then it’s fine. Some manufacturers using domestically produced fiber membranes have been doing so for over 10 years now
Is it possible that the air intake volume of the membrane unit is significantly higher than it was a year ago, and is this related to pressure? The volume of air will vary depending on the pressure. Besides, as long as your equipment meets the process requirements, isn’t the air intake volume entirely under your control? Currently, membrane suppliers generally guarantee a service life of the membranes of at least 10 years.
Reply to 3# wawjia: The pressure remains stable and unchanged
Let’s analyze the components of imports and exports! If the components are normal, then there’s nothing to worry about!
