Method for removing acid gases from a gaseous Stream in which the sum of the partial pressures of the acid gases does not exceed 1.500 mbar and operates by contacting the stream with an aqueous medium Absorption which contains at least one alcanolamina Tertiary And piperazine.

摘要

The Invention relates to a method for removing acid gases from a gas Stream, in which a gaseous Stream containing acid gasIn where the sum of the partial pressures of the gases acids did not exceed 1500 mbarGets in contact with an aqueous medium absorption in a step of Absorption and uses an Absorption Medium containing metildietanolamina and piperazine in a concentration of at least 8% in PESo D and Poor Absorption, resulting in a gaseous Stream and an Acid gas Absorption Medium loaded with acid gases.
