Abstract:
1. A process for treating an acid feed gas, comprising: bringing the acid feed gas into contact with a gas permeable membrane; said gas permeable membrane being in simultaneous contact with a permeate comprising a caustic solution in such a manner as to allow for the permeation of gases between said acid feed gas and said permeate, wherein the acid feed gas and the permeate are on opposite sides of the gas permeable membrane; wherein at least one acid gas is at least 50% removed from said acid feed gas by permeation of said acid gas through said gas permeable membrane and reaction of said acid gas with the caustic of said caustic solution of said permeate on the permeate side of the gas permeable membrane; and wherein said reaction produces a salt.
