Fcc stripped dp problem

Fcc stripped dp problem

Fcc stripped dp problem

(OP)
Our fluid Catalytic Cracking unit, commissioned an year ago, is constrained with high stripper/absorber pressure drop problems. When stripper feed temp was 42 deg, stripper exhibited high del pr even at 80% loads. After failure of HPS inlet condensers cooling water exchangers, the stripper feed temp increased to 67 deg C. Though the stripper del P peaked around at 95% load, but absorber column del P exceeded the max operating value.
What may be reasons behind stripper del P incursions? What is the optimum stripper feed temperature

RE: Fcc stripped dp problem

Ask the engineer that works on the stripper.

RE: Fcc stripped dp problem

you would need to supply a P&ID and equipment information to answer that question
