Thanks for your response,
We were able to bypass and open up the Gas Absorber for inspection of the trays; found Significant Fouling and plugging on at some of the bottom trays, possible due to Contaminants in System/Solution, Heat Stable Salts and degradation in Amine Products.
A combination of High Soluble Iron with very high Coker gas absorber Inlet H2S Concentration Yields Iron Sulfide which lead to corrosion, plugging of the trays causing foaming and flooding in my Coker Gas absorber.
