    Our coker gas DEA contactor, with random packing, is prone to chronic fouling which we presume is due to entrained light gas oil from the upstream sponge absorber. What is the experience with off-line chemical cleaning?

    Did you rule out the fouling is iron sulfide build-up?  Suggest scan of packed beds.  This will show area of fouling.  If iron sulfide, water wash the tower.

    What about the DEA analysis (HSS, metals,color, etc)?
