ABSORBENT FOR REMOVING CARBON DIOXIDE FROM FLUE GAS WITH IMPROVED ABSORPTION SPEED REGARDING CARBON DIOXIDE

摘要

PURPOSE: To provide an absorbent for removing carbon dioxide from a mixture gas containing acidic gases such as CO2, H2S, COS and the like, which is able to significantly increase reaction speed between tertiary alkanol amine and the acidic gases. CONSTITUTION: The absorbent consists of at least one tertiary alkanol amine and an additive for improving absorption speed regarding the tertiary alkanol amine such as N-methyl-diethanolamine that is selected from 3,3'-diaminopropyl amine(DADPA) or N-(2-aminoethyl)-1,3-propane diamine(AEPDA).
