Abstract Amine absorption processes designed to remove acid gases from gas streams generally face a major challenge of solvent degradation. This degradation leads the formation heat-stable salts (HSS), corrosive agents that irreversibly bind free alkanolamine. The present study proposes, for first time, method HSS perstraction using liquid–liquid membrane contactor allows transfer through porou...

alkanolamine solutions such as 2-amino-2-methyl-1-propanol (amp) are widely used in chemical industries for the removal of acid gases such as co2 and h2s. in this work, the density of co2, amp, water, and amp solutions using the goharshadi–morsali–abbaspour equation of state “gma eos” in the extended 50-degree range of temperatures (313.06-362.65 k) and pressures (0.5-40 mpa) was calculated. th...
