Abstract

Procédé pour le déparaffinage au solvant d'huiles contenant de la paraffine. Des polyalcoyl acrylates sont utilisés comme agents de modification des cristaux conjointement avec la division en portions de la charge d'huile de départ de manière qu'on obtienne un de la charge d'huile de départ de manière qu'on obtienne un rapport initial solvant/huile de trois ou plus. L'invention est spécialement importante pour le déparaffinage d'huiles telles que des résidus courts qui restent comme résidu de distillation de pétroles bruts étêtés dont toutes les fractions plus légères; jusqu'aux fractions d'huiles de distillation, inclusivement, ont été enlevées.
