I. Product Introduction
DKJ-HS-G high-temperature corrosion inhibitor is an effective naphthenic acid, sulfide corrosion inhibitor developed for solving the serious corrosion problems on high-temperature parts in processing of high acid value and high-sulfur crude oil by our company's institute. The product adapts to high temperature which can be used directly in the processing of high temperature crude oil. It is an effective solution to the problem of naphthenic acid corrosion under high temperature conditions. It can be dissolved in polar and non-polar solvents and easy to use. The agent does not contain metal elements with no effect on the subsequent refining process.
