OPTIMIZING FEED MIXER PERFORMANCE IN A PARAFFINIC FROTH TREATMENT PROCESS

The invention relates to improved bitumen recovery processes and systems. One process provides for operation of a bitumen froth treatment plant at optimum shear rates in the feed pipe carrying the bitumen froth to the froth settling unit. Another process provides for optimizing the design of a bitum...

Zusammenfassung:	The invention relates to improved bitumen recovery processes and systems. One process provides for operation of a bitumen froth treatment plant at optimum shear rates in the feed pipe carrying the bitumen froth to the froth settling unit. Another process provides for optimizing the design of a bitumen froth treatment plant by optimizing the diameter of the feed pipe to impart an optimum shear rate to the bitumen froth mixture and further optimizing the volume of the feed pipe to impart an optimum residence time for the bitumen froth stream in the feed pipe. An optimal plant design is also disclosed, the plant including optimal diameter and volume of the feed pipe. Linvention concerne des processus et des systèmes de récupération améliorée du bitume. Un processus permet le fonctionnement dune usine de traitement de lécume de bitume selon des taux de cisaillement optimaux dans le tuyau dalimentation transportant lécume de bitume vers lunité de décantation de lécume. Un autre processus permet doptimiser la conception dune usine de traitement de lécume de bitume en optimisant le diamètre du tuyau dalimentation afin dassurer un taux de cisaillement optimal au mélange décume de bitume, puis en optimisant davantage le volume du tuyau dalimentation pour assurer un temps de séjour optimal du flux décume de bitume dans le tuyau dalimentation. Une conception dusine optimale est également présentée, ladite usine offrant un diamètre et un volume optimaux pour le tuyau dalimentation.
