Abstract
The corrosion of iron and steel by an aqueous sour gas conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a quaternary pyridinium salt and an organic thioamide, a water-soluble sulfide or a water-soluble thiocyanate.
Claims13
A sour gas conditioning solution inhibited against CO.sub.2 promoted corrosion of iron and steel by having dissolved therein an inhibiting concentration of a combination of one part by weight of a quaternary pyridinium salt and about 0.001-10 parts of a thio compound which is a water-soluble thiocyanate, a water-soluble sulfide, or an organic thioamide.
