In hydro-processing reactors, pressure drop is mainly induced by particulate build-up and gum formations, as well as scales from the unit equipment or particulates formed within the unit itself. Inert bed grading is a proper arrangement of high void-fraction bed grading materials with decreasing size, various porosities, and increased surface activities, designed to ensure maximum retention while minimizing pressure drop.
NPIBG FR90 is an inert alumina fluted ring with a high void fraction to trap particulates and other contaminants in the feed to mitigate pressure drop build-up.
APPLICATION:
This product can delay pressure drop and rise in the bed.
