12/11/2022 0 Comments Amine absorber tray efficiency![]() O When pushing unit rates, amine loading, fluctuations in pressures and flows can “overwhelm” the amine and H2S can breakthrough. O Set minimum amine circulation based on maximum H2S recycle content O Controlling lean amine flow based on temperature rise of amine coming in or out of contactor (relatively new ) O Sampling rich amine and determining H2S loading for optimization (reduce amine circulation) We have seen corrosion in rich amine piping likely due to elevated H2S loadings and higher velocities (both lean and rich), especially when unit rates are changed quickly.Īdjust amine circulation to maintain desired rich amine loading (Typically 0.3-0.45 mol total acid gas / mol of amine loading). The biggest key factor in amine contactor operation in hydroprocessing units is controlling the lean amine flow and the lean and rich amine loading. ![]()
