Abstract
A corrosion inhibitor composition useful for preventing corrosion by solvents used in treating sour gas streams, comprising a quaternary pyridine salt, a surface-active agent and/or a thio compound and an effective amount of a water soluble nickel compound. The composition can also contain a demulsifier to prevent foaming of the resultant solution.

An inhibiting composition, comprising a water soluble quaternary pyridine salt, a sufficient amount of a surface-active agent, and an effective amount of a water soluble nickel compound.
A conditioning solution inhibited against CO.sub.2 and H.sub.2 S promoted corrosion of ferrous materials by having dissolved therein an inhibiting composition, comprising a quanternary ammonium compound of benzyl chloride and the residue boiling between 200.degree. C. and about 350.degree. C. from the distillation of an acid extract of the reaction product of ammonia and acetaldehyde, a sufficient amount of a surface-active agent, and an effective amount of a water soluble nickel compound.
