Title (EN) ACRYLAMIDE-BASED COPOLYMERS, TERPOLYMERS, AND USE AS HYDRATE INHIBITORS
(FR) COPOLYMÈRES, TERPOLYMÈRES À BASE D'ACRYLAMIDE ET UTILISATION EN TANT QU'INHIBITEURS D'HYDRATES
Abstract:
(EN) Copolymers having General Formula (I): (I) in which R1, R2, and R3 are chosen from C1 to C30 aliphatic groups, R4 is chosen from divalent C4 to C7 linear aliphatic groups and divalent C4 to C7 linear heteroaliphatic groups, optionally substituted with one or more C1-C6 linear aliphatic groups, C1-C6 branched aliphatic groups, or combination thereof, R5, R6, and R7 are each independently chosen from methyl or hydrogen, x is chosen from 0 to 0.8, y is chosen from 0 to 0.8, when y is 0, x is greater than 0, and when x is 0, y is greater than 0, and z is chosen from 0.1 to 0.9. The summation of x, y, and z equals 1. Methods for inhibiting formation of clathrate hydrates in a fluid capable of forming the clathrate hydrates, including contacting the fluid with at least one copolymer of General Formula (I).
(FR) L'invention concerne des copolymères présentant la formule générale (I) : (I) dans laquelle R1, R2 et R3 sont choisis parmi des groupes aliphatiques en C1 à C30, R4 est choisi parmi les groupes aliphatiques linéaires divalents en C4 à C7 et les groupes hétéroaliphatiques linéaires divalents en C4 à C7, éventuellement substitués par un ou plusieurs groupes aliphatiques linéaires en C1-C6, par un ou plusieurs groupes aliphatiques ramifiés en C1-C6 ou une combinaison correspondante, R5, R6 et R7 sont choisis, chacun indépendamment, parmi méthyle ou hydrogène, x est choisi de 0 à 0,8, y est choisi de 0 et 0,8, lorsque y vaut 0, alors x est supérieur à 0 et lorsque x vaut 0, alors y est supérieur à 0, et z est choisi de 0,1 à 0,9. La somme de x, y et z vaut 1. L'invention concerne également des procédés pour inhiber la formation d'hydrates de clathrate dans un fluide pouvant former les hydrates de clathrate, comprenant la mise en contact du fluide avec au moins un copolymère de formule générale (I).
