Abstract
Il est décrit un procédé de récupération de solvants qui peut être utilisé pour récupérer des solvants plus précieux et relativement plus lourds utilisés pendant un procédé de production de bitume continu en cours ou récemment achevé. Le procédé de récupération de solvants fonctionne en utilisant un solvant relativement plus léger que le solvant précédemment utilisé pour augmenter la récupération dun ou de plusieurs des solvants plus lourds et plus chers coincés ou autrement retenus dans le réservoir. Le solvant relativement plus léger demeure en phase vapeur lorsquil est injecté dans la chambre et maintient la pression dans le réservoir, qui agit pour i) réduire la pression partielle du solvant plus lourd qui est visé aux fins de récupération, ce qui entraîne la vaporisation de ce solvant, et ii) déplacer le solvant plus lourd en phase vapeur. Cela peut améliorer la rentabilité de divers procédés de récupération de bitume qui utilise un solvant au moins partiellement, comme, par exemple, des procédés qui utilisent le solvant avec le chauffage à vapeur et/ou électromagnétique.
