Title
(EN) ION PAIR AMPHIPHILES AS HYDRATE INHIBITORS
(FR) AMPHIPHILES DE PAIRE D'IONS UTILISES COMME INHIBITEURS D'HYDRATES
Abstract
(EN) A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of one or more ion-pair amphiphiles, wherein the ion-pair amphiphiles are composed of one or more cationic amphiphiles and one or more anionic amphiphiles.
(FR) La présente invention concerne un procédé d'inhibition d'hydrates dans un fluide comprenant de l'eau et du gaz, qui consiste à ajouter à ce fluide une quantité inhibitrice d'hydrates efficace d'un ou de plusieurs amphiphiles de paire d'ions, ces amphiphiles de paire d'ions étant composés d'un ou de plusieurs amphiphiles cationiques et d'un ou de plusieurs amphiphiles anioniques.
