METHOD FOR REGENERATION OF AN ACID GAS ABSORBING FLUID CONTAINING METHYLDIETHANOLAMINE AND A (LOWER ALKYL) PIPERAZINE

摘要

A method for the regeneration of an acid gas absorbing fluid which comprises bringing a gaseous mixture containing an acid gas into contact with an absorbing fluid containing methyldiethanolamine and a (lower alkyl)piperazine so as to absorb the acid gas into the absorbing fluid, and regenerating the absorbing fluid by releasing the acid gas from the absorbing fluid in a regeneration tower having a temperature of not less than 40.degree.C.
