Patent

CA 2319566

In a process for separating oily films from sand particles carried in a solvent free water stream, the use of a jet pump scrubber in a density classification tank to treat such oily coated particles at controlled operating temperatures above 65 °C whereby at such controlled temperature enhanced cavitation in said jet pump separates said oily film from said sand particles to form slop oil, said tank providing for recirculation of sand particles through said jet pump before discharge.

L'invention concerne un procédé de séparation de films huileux des particules de sable contenus dans un courant d'eau exempt de solvant qui consiste à utiliser un épurateur à pompe à jet dans un réservoir de classification de densité pour traiter de telles particules enduites de pétrole à des températures opérationnelles régulées au-dessus de 65 DEG C. A une telle température régulée, la cavitation améliorée dans ladite pompe à jet sépare ledit film huileux desdites particules de sable pour former des rejets de fabrication, ledit réservoir permettant la recirculation des particules de sable à travers la pompe à jet avant l'évacuation.
