Catalyst poison removal | Phosphorus removal

Frequently added to crude as a corrosion inhibitor and often found in renewable feedstocks, phosphorus can inhibit your hydrotreating catalysts by blocking access to the catalyst interior. In the case of renewables, fast-reacting phosphor lipids can also cause pressure drops. Whatever the source, even a few ppm of phosphorus in your feedstock can take a serious hit on your plant’s performance.

There is no easy way to guard against phosphorus, but decades of experience with grading and guard catalysts have given Topsoe deep insight into optimal catalyst shapes and porosity for this difficult task. Our proven hydrodemetallization (HDM) loading schemes will protect your reactor with the industry’s highest phosphorus uptake.
