Document Type and Number:
WIPO Patent Application WO/2024/092599
Kind Code:
A1
Abstract:
Additives, and methods of making and using the additives are described. The additives may be provided as concentrates for addition to one or more hydrocarbons in crude oil refining and processing facilities to inhibit corrosion of corrodible metal parts in contact with the process streams. The additives may be made by reacting glycerol-restricted vegetable oil fatty acid with amine, wherein the glycerol-restricted vegetable oil fatty acid may be a hydrolyzed vegetable oil that is at least partially purified with respect to glycerol. The additives may be further reacted to provide ammonium salts that may be added to aqueous compositions to provide corrosion protection of corrodible surfaces in contact with the aqueous compositions.
