The present disclosure relates to a gas hydrate inhibitor composition comprising from an amphiphile having a hydrophobic tail linked to a hydrophilic head group by a linking moiety, the amphiphile having the general formula (1)[R-L-N(R)(R)(R)]X  (1) from a cationic surfactant which is selected from di(C-Calkyl)dimethyl ammonium salts.

Synergistic blends of anti-agglomerant gas hydrate inhibitors with quaternary alkyl ammonium compounds

Provided herein is a method for inhibiting gas hydrate formation in a system containing hydrocarbons and water. The method includes contacting the system with a gas hydrate inhibitor composition including an amidoamine of a fatty acid, optionally in the form of a cationic ammonium compound, and a nonionic surfactant selected from alkoxylated C-Cfatty alcohols, alkoxylated C-Cfatty amines, alkoxylated C-Cfatty acids and alkoxylated C-Cfatty acid amides.

Method of and a composition for controlling gas hydrate blockage through the addition of a synergistically acting blend with alkoxylates of fatty alcohols, fatty amines and fatty acids

Disclosed is a gas hydrate inhibitor composition comprising an amphiphile by a linking moiety, the amphiphile having of the general formula (1)[R-L-N(R)(R)(R)]X  (1) wherein each of Rand Ris an alkyl group having from 1 to 5 carbon atoms; or wherein the nitrogen atom and the Rand Rgroups together form a heterocyclic group; Ris present or not as hydrogen or an alkyl group having from 1 to 8 carbon atoms L is a linking moiety comprising a hydrocarbyl group having at least 2 adjacent carbon atoms, at least one heteroatom selected from nitrogen and oxygen, Ris a hydrocarbyl group having from 6 to 22 carbon atoms; and X− is present as an anion when Ris present; and a cationic surfactant which is selected from quaternary benzyl ammonium salts and a method of using the gas hydrate inhibitor composition.
