•Technical Paper: Effectiveness Of Continuous Removal Of Heat Stable Salts From Contaminated Amine Scrubbing Solutions

The amine-treating unit is of great importance in gas processing and refinery operations for treating acid gases and now attracts increasing attention due to the pressing needs of environmental compliance and meeting the stringent levels of H2S and CO2 removal. Lean amine solutions of 20-50 wt.% and relatively free of acid gases enters the top of the absorption tower and flows counter-current to the sour gas stream being fed from the bottom of the column. The acid gases in the gas stream are chemically absorbed resulting in rich amine solution that exits from the bottom of the tower and the sweet gas from the tower top.
Thermal regeneration of the rich amine is then carried out in a steam stripper where the absorbed acid gases are liberated and this regenerated (lean) amine is re-circulated back to the absorption tower top.
