Why Is Your Ethylene/Propylene Purification Adsorbent Bed Breaking Through Early? Troubleshooting Guide
Early breakthrough in a CuO-ZnO ethylene/propylene purification bed is rarely just "the media is used up." This guide breaks down four distinct failure mechanisms — sulfate formation, moisture overload, copper sintering, and COS slip — and how to tell which one is driving your early breakthrough.

What Happens If You Skip CD Adsorbent and Go Straight from COS Removal to Polymerization?
Bypassing the CD adsorbent bed in an olefin purification train is a serious engineering misstep. This guide explains why oxygenates and moisture that slip past a COS adsorbent bed can permanently poison downstream polymerization catalysts — and why the two beds are not interchangeable.
