Compounds and methods for inhibiting corrosion in hydrocarbon processing units

摘要

Treatment compositions for neutralizing acidic species and reducing hydrochloride and amine salts in a fluid hydrocarbon stream are disclosed. The treatment compositions may comprise at least one amine with a salt precipitation potential index of equal to or less than about 1.0. Methods for neutralizing acidic species and reducing deposits of hydrochloride and amine salts in a hydrocarbon refining process are also disclosed. The methods may comprise providing a fluid hydrocarbon stream and adding a treatment composition to the fluid hydrocarbon stream. The treatment compositions used may have a salt precipitation potential index of equal to or less than about 1.0 and comprise either water-soluble or oil-soluble amines.

主权项

1. A method for neutralizing acidic species and reducing deposits of hydrochloride and amine salts in a hydrocarbon refining process comprising:
(a) providing a fluid hydrocarbon stream; and (b) adding a treatment composition to said fluid hydrocarbon stream, said treatment composition comprising at least one amine with a salt precipitation potential index of equal to or less than about 1.0, wherein said amine comprises at least one member selected from the group consisting of: di-ethyl propargylamine, 1,4-dimethyl piperazine, N-methylpyrrolidine, and furfurylamine, wherein said treatment composition is added to said fluid hydrocarbon stream in an amount of from 1 to about 1,000 ppm by volume of said fluid hydrocarbon stream.
