METHOD OF INHIBITING NITROSATION OF AN AQUEOUS AMINE SOLUTION USED IN A PROCESS OF REMOVING CARBON DIOXIDE FROM A FLUE GAS

摘要

A method is provided for inhibiting nitrosation of an aqueous amine solution used in a process of removing carbon dioxide from a flue gas. That method includes a step of adding an effective amount of an antioxidant to the aqueous amine solution being circulated between an absorber and a stripper of a carbon dioxide capture system.
