(EN) ANTI-AGGLOMERANT HYDRATE INHIBITORS AND METHOD OF USE
(FR) INHIBITEURS D'HYDRATE ANTI-AGGLOMÉRANT ET PROCÉDÉ D'UTILISATION
Abstract
(EN)
Compositions and methods of using such compositions to inhibit the formation of gas hydrate agglomerates are provided. In certain embodiments, the methods include: contacting a fluid with a hydrate inhibitor composition that includes at least one compound having the structural formula (I) wherein R1 is hydrogen or any C1 to C8 hydrocarbon chain; each of R2 and R3 is independently a C1 to C8 hydrocarbon chain; R4 is hydrogen, a C1 to C20 hydrocarbon chain, or -CH2-CH(OH)-R5; R5 is a C1 to C50 alkyl chain or a C1 to C50 alkenyl chain; X- is a counter anion; and n is an integer from 1 to 8.

La présente invention concerne des compositions et des procédés d'utilisation de ces compositions pour inhiber la formation d'agglomérats d'hydrate de gaz. Dans certains modes de réalisation, les procédés comprennent : la mise en contact d'un liquide avec une composition d'inhibiteur d'hydrate qui comprend au moins un composé ayant la formule structurelle : où R1 est un atome d'hydrogène ou une quelconque chaîne hydrocarbonée en C1 à C8; chacun de R2 et R3 est indépendamment une chaîne hydrocarbonée en C1 à C8; R4 est un atome d'hydrogène, une chaîne hydrocarbonée en C1 à C20, ou -CH2-CH(OH)-R5; R5 est une chaîne alkyle en C1 à C50 ou une chaîne alcényle en C1 à C50; X- est un contre-anion; et n est un nombre entier d'une valeur de 1 à 8.
