Physical solvent for gas sweetening
Patent
·
OSTI ID:6091174
This invention relates to a novel solvent, N-2-methoxyethyl-2-pyrrolidone, that can be used in two ways. First, in the pure or undiluted form, it absorbs hydrogen sulfide and other sulfurous gases selectively and simultaneously dries the gas. Second, when mixed with an alkanolamine and water, it is a superior absorbent of mercaptans, sulfides, and disulfides, and removes acid gases.
