Abstract: A reclaimer system and methods for using said reclaimer system to reclaim one or more amine agents from a fluid containing one or more degradation products that have been formed from the reaction of one or more acid gas components with the one or more amine agents.

Abstract: An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system.

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.
