Abstract:
This invention relates to a process for the separation of carbon dioxide and hydrogen sulfide from gases using a promoted methyldiethanolamine (MDEA) solution. In one broad respect, this invention is a gas separation process, including contacting an aqueous treating solution with a sour gas stream that contains carbon dioxide and hydrogen sulfide under conditions such that the gas stream is sweetened, wherein the aqueous treating solution contains methyldiethanol amine and 2-(2-aminoethoxy)ethanol in a ratio of at least about 2:1; and wherein the process is conducted in the absence of a reclamation step. By practice of this invention, the amount of 2-(2-aminoethoxy)ethanol that is converted to urea(bis-(2-hydroxyethoxyethyl)urea (BHEEU)) is minimized which obviates the need for a reclamation (regeneration) unit.
