A method for inhibiting the plugging of a conduit by gas hydrates comprises adding to a mixture of water and hydrocarbons flowing through the conduit an amount of a hydrate formation inhibitor component of formula (a), wherein two of R1-R4 are independently normal or branched alkyls having 4 or carbon atoms, two of R1-R4 are independently representing organic moieties having at least 8 carbon atoms, A represents a nitrogen or phosphorus atom, and Y represents an anion.
Ce procédé destiné à empêcher le bouchage d'un conduit par des hydrates de gaz consiste à ajouter à un mélange d'eau et d'hydrocarbures circulant à travers le conduit, une quantité d'un composant de la formule (a), lequel est un inhibiteur de la formation d'hydrates. Dans cette formule, deux des R1-R4 représentent indépendamment des alkyles normaux ou ramifiés possédant 4 ou 5 atomes de carbone, deux des R1-R4 représentent indépendamment des fractions organiques possédant au moins 8 atomes de carbone, A représente un atome d'azote ou de phosphore et Y représente un anion.
