Anvendelse av vannl degree selig polymer til inhibering av dannelsen av gasshydrater, fremgangsmåte til inhibering av gasshydratdannelse samtanvendelse av en kjemisk forbindelse som et additiv

摘要

The instant invention relates to the use of water-soluble polymers comprising structural elements of formula (I) wherein each R is independently H or C1-5-alkyl; X is H, an alkaline or earth alkaline metal or a quaternary ammonium group; R1 is H or C1-18-alkyl; and R2 is C1-18-alkyl; and wherein the alkyl groups represented by R1 and R2 may carry a hydroxy or amino substituent; and, if desired, a minor proportion of structural elements of formula (II) wherein R, R1, R2 and X may have the meaning as above, and Alk is a C1-C5-alkylene chain, as additives for inhibiting the formation of gas hydrates in connection with hydrocarbon production and transportation.
