How Do You Know When to Replace Molecular Sieve in a PSA Hydrogen Purification Unit?
5A molecular sieve in a PSA hydrogen purification unit gradually loses capacity from moisture, CO2 slip, mechanical attrition, and thermal aging. Learn the early warning signs — purity drift, shorter cycle times, rising pressure drop — so you can plan a changeout before an off-spec hydrogen stream forces one.
