Use of sulfiding agents for enhancing the efficacy of phosphorus in controlling high temperature corrosion attack

摘要

The invention comprises a method of inhibiting naphthenic acid corrosion in a high temperature hydrocarbon system, comprising adding to the system a corrosion-inhibiting amount of a phosphate ester and a corrosion-inhibiting amount of a phosphate ester and a corrosion-inhibiting amount of organic polysulfide.
