Beschreibung
Zusammenfassung:	A method and a quaternary ammonium or phosphonium composition used therein for inhibiting, retarding, mitigating, reducing, controlling and/or delaying formation of hydrocarbon hydrates or agglomerates of hydrates. The method may be applied to prevent or reduce or mitigate plugging of conduits, pipes, transfer lines, valves, and other places or equipment where hydrocarbon hydrate solids may form under the conditions. At least one quaternary ammonium or phosphonium compound is added into the process stream, where the compound may be mixed with another compound selected from other amino alcohols, esters, quaternary ammonium, phosphonium or sulphonium salts, betaines, amine oxides, amides, simple amine salts, and combinations thereof. L'invention concerne un procédé et une composition de phosphonium et d'ammonium quaternaire utilisé dans celui-ci pour inhiber, retarder, atténuer, réduire, supprimer et/ou retarder la formation d'hydrates d'hydrocarbure ou d'agglomérats d'hydrates. Ce procédé peut être appliqué pour empêcher, réduire ou atténuer l'obturation de conduits, tuyaux, lignes de transfert, vannes et autres sites ou équipement dans lesquels de l'hydrate d'hydrocarbure solide peut se former dans certaines conditions. Au moins un composé de phosphomiun ou d'ammonium quaternaire est ajouté dans le courant de traitement, ce composé pouvant être mélangé à un autre composé choisi parmi d'autres amino-alcools, esters, ammonium quaternaire, sels de phosphonium ou de sulphonium, bétaïnes, oxydes d'amine, amides, sels d'amine simple et des combinaisons de ceux-ci.
