VANADIUM-COBALT CORROSION INHIBITOR SYSTEM FOR SOUR GAS CONDITIONING SOLUTIONS

摘要

VANADIUM-AMINE CORROSION INHIBITOR SYSTEM FOR SOUR GAS CONDITIONING SOLUTIONS The corrosion of iron and steel surfaces by an aqueous alkanolamine conditioning solution used to remove CO2 from a gas stream is effectively inhibited by a combination of (a) a vanadium containing ion and (b) a cobalt salt or a diamine or triamine. A surprising fact is that some of the amine co-inhibitors have been identified by others in the art as promoting ferrous metal corrosion.
