Abstract

L'invention a pour objet un additif essentiellement constitué d'une amine grasse oxyalkylée ou d'un dérivé d'une telle amine et d'un composé de sel métallique spécial, de préférence un savon métallique. Cet additif pour huiles lourdes provoque une bonne émulsification ou dispersion des asphaltènes et d'autres composés à haut poids moléculaire, ce qui entraîne, notamment, une stabilité au stockage élevée, une aptitude au pompage améliorée du fait de la moindre viscosité de l'huile et une plus longue durée d'utilisation des systèmes de filtration. Il assure en outre une combustion améliorée des huiles lourdes. La quantité efficace en additif dans ces huiles est de l'ordre de 2 à 2000 ppm. Les huiles selon l'invention sont utilisées notamment comme combustibles pour des installations industrielles et des centrales et comme carburants pour moteurs de bateaux.
