ABSTRACT:
The corrosion of metals in contact with aqueous alkanolamine solution in acid gas removal units is inhibited by adding to the alkanolamine solution a corrosion inhibiting amount of a sulfur containing heterocyclic ring compound. The ring compounds are useful for inhibiting the corrosion of metals in both the acid gas rich and the acid gas lean portions of the acid gas removal unit.
