Abstract

This invention relates to inhibiting corrosion in systems of condensing hydrocarbons which contain water and chlorides, and, more particularly, in the overhead of crude oil atmospheric pipestills, with blends of amines. Preferred blends are 2-amino-1-methoxypropane, sec-butylamine, n-butylamine, dipropylamine and monoamylamine; 2-amino-1-methoxypropane, sec-butylamine, monoamylamine, n-butylamine and isobutylamine; and sec-butylamine, 2-amino-1-methoxypropane and 3-amino-1-methoxypropane.
