Abstract

L'invention concerne un procédé et un système pour manipuler des sables bitumineux et extraire du bitume ou du pétrole à partir des sables bitumineux. Le procédé comprend les étapes consistant à déposer des sables bitumineux dans un ensemble trémie ayant un fond conique. Un mélange de solvants organiques est pulvérisé sur les sables bitumineux par une série de jets proches des parois de la trémie. Le pétrole ou le bitume dans les sables bitumineux est dissous par le mélange de solvants organiques. Le sable provenant des sables bitumineux se sépare et tombe vers le fond de l'ensemble trémie. Les sables et le liquide dans une boue de fluides sont transportés de l'ensemble trémie à une chambre de rinçage. La boue de fluides est acheminée dans le haut de la chambre de rinçage tangentiellement pour provoquer une action cyclonique de la boue dans la chambre de rinçage. Le solvant introduit à la base de la chambre de rinçage et le mélange de solvants sont extraits depuis le haut de la chambre de rinçage. Par la suite, le mélange liquide de solvants et d'hydrocarbures est pompé vers un séparateur pour séparer le pétrole et le bitume du solvant. Enfin, le solvant propre est renvoyé pour être réutilisé par une introduction dans la chambre de rinçage afin de former un processus en boucle fermée.
