An overbased magnesium composition deposit control additive for residual fuel oils and turbine fuels is an overbased magnesium sulfonate, carboxylate or phanate or mixtures thereof containing at least 14 % and upwards to about 18 % by weight of magnesium and containing a succinic anhydride and lower carboxylic acid co-promoter reaction product. The additive when added to fuel oils, such as residual fuel oils containing high asphaltenes, reduces, if not eliminates, magnesium/asphaltene deposits or sediment and the consequential plugging of filters. The additive also reduces, if not eliminates, vanadium caused corrosion in the turbine. The invention is also the process for preparing the overbased composition or deposit control additive, wherein the overbasing reaction incorporates the combination of a lower carboxylic acid, preferably acetic acid and a succinic anhydride, preferably dodecenyl succinic anhydride (DDSA), as the co-promoter.

L'invention porte sur une composition surbasique au magnésium pour additif de réduction des dépôts dans les fiouls lourds ou les carburants pour turbines consistant en un sulfonate, carboxylate ou phénate de magnésium surbasique, ou leur mélange, et contenant au moins 14 % et jusqu'à environ 18 % en poids de magnésium ainsi que de l'anhydride succinique et un produit de réaction copromoteur d'un acide carboxylique inférieur. Cet additif, ajouté aux fiouls tels que les fiouls lourds à forte teneur en asphaltène réduit s'il n'élimine pas les dépôts ou sédiments de magnésium/asphaltène et l'encrassage des filtres en découlant. Cet additif réduit s'il n'élimine pas la corrosion des turbines due au vanadium. L'invention porte également sur le procédé de préparation de la composition surbasique et de l'additif de réduction des dépôts dans lequel la réaction de surbasicité utilise une combinaison d'un acide carboxylique inférieur, de préférence de l'acide acétique, et d'un anhydride succinique, de préférence de l'anhydride dodécénylsuccinique (DDSA) comme copromoteur.
