Method of controlling gas hydrates in fluid systems |
摘要 |
A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more copolymers of N-alkyl (alkyl)acrylamide monomers and one or more cationic monomers selected from acid and alkyl chloride quaternary salts of N,N-dialkylaminoalkyl (meth)acrylates and N,N-dialkylaminoalkyl (meth)acrylamides. |

1. A method of inhibiting hydrate formation in a fluid comprising water, gas and optionally liquid hydrocarbon comprising treating the fluid with an effective hydrate-inhibiting amount of an inhibitor composition comprising a cationic copolymer derived by polymerization of about 75 to about 99.9 mole percent of N-alkyl alkylacrylamide or N-alkyl acrylamide monomer units and about 0.1 to about 25 mole percent of alkylacrylamidoalkyltrialkylammonium chloride or acrylamidoalkyltrialkylammonium chloride monomer units. |
