titleOfInvention PROCESS FOR INHIBITING CORROSION OF STEEL IN THE PROCESS OF ABSORPTION OF CARBON DIOXIDE GAS
abstract A method for inhibiting the corrosion of steels used for apparatus for removing gaseous carbon dioxide, characterized in that in a method for absorbing and removing gaseous carbon dioxide in synthesis gas using a solution as absorbent 1-hydroxyethylidene-1,1-diphosphonic acid is added to the aqueous carbonate solution. According to this process, the corrosion of steels can be inhibited without using conventional Na2 CrO4, V2 O5, etc., which are subject to pollutant control.
