  • Publication number: 20050132641
    Abstract: It has been discovered that compositions that are blends or mixtures of certain lubricity additives and corrosion inhibitors and/or stability additives can serve as improved lubricity additive compositions in distillate fuels. The corrosion inhibitors may include, but are not necessarily limited to, saturated or unsaturated monomer, dimer, and trimer fatty acids, succinic acids, imidazolines, and mixtures thereof. Suitable stability additives include, but are not necessarily limited to, amines, amides, amine/aldehyde condensates, polymer dispersants, and mixtures thereof, where the stability additive is different from the lubricity additive. It has been surprisingly discovered that less lubricity additive may be used in the compositions when the stability additive or corrosion inhibitor is present to achieve the same lubricity result, as compared with compositions that do not contain a stability additive or corrosion inhibitor, yet the same total amount of additive composition.

  • Publication number: 20050000862
    Abstract: Corrosive amine salts in hydrocarbon streams such as desalted crude oil streams can be prevented or avoided by adding certain amine scavenging chemicals to the streams. Suitable amine scavengers include, but are not necessarily limited to, carboxylic anhydrides and copolymers of carboxylic anhydrides, aromatic anhydrides, isocyanates, polyisocyanates, and epoxides. The non-corrosive reaction products of the amines and/or ammonia with these scavengers are preferably oil-soluble, non-basic and thermally stable. The amine scavengers bind up and react with the amines and/or ammonia to keep them from reacting with materials such as acids (e.g. HCl) to form corrosive amine salts.
