ABSTRACT:
A process for removing H2S and mercaptans from gas streams. The process comprises contacting such gas streams with an aqueous solution of copper complex of a water soluble amine to form water insoluble copper sulfide and regenerate free water soluble amine. The copper sulfide is removed from the system and recovered. Lastly, additional copper complex of the water soluble amine is formed by reacting the regenerated water soluble amine with a copper compound.
