Title (EN) ASPHALTENE INHIBITION
(FR) INHIBITION DE L'ASPHALTÈNE
Abstract: front page image
(EN)A method of inhibiting asphaltene precipitation and/or deposition in a hydrocarbon, preferably crude oil, by adding to the hydrocarbon a polyester asphaltene dispersing agent which is the reaction product of an alk(en)yl substituted succinic anhydride wherein the average number of succinic groups per alk(en)yl group is less than 2.0, and at least one polyol.
(FR)L'invention concerne un procédé d'inhibition de la précipitation et/ou du dépôt d'asphaltène dans un hydrocarbure, de préférence du pétrole brut, par addition à l'hydrocarbure d'un agent de dispersion d'asphaltène de polyester qui est le produit de réaction d'un anhydride succinique substitué par alcényle/alkyle, le nombre moyen de groupes succiniques par groupe alcényle/alkyle étant inférieur à 2,0, et d'au moins un polyol.
