Pressure drop control

Pressure drop control Pressure drop in hydroprocessing units is usually the result of an accumulation of a dense layer of particulates or the formation of gums from reactive species in the feed. Both of these problems can be solved with proper bed grading to significantly increase cycle length and prevent premature shutdown.

Control of particulates involves using large diameter and large void fraction catalysts to spread out the zone of deposition of particulates. Each layer of catalyst of a particular shape and size collect particulates within a certain size range and prevents formation of a dense layer of particulate accumulation.

Pressure drop due to gum formation is prevented by grading catalyst activity so the gum forming reactions controlled and spread out over a larger portion of the catalyst bed.
