RECOVERY OF SOLVENT FROM DILUTED TAILINGS BY FEEDING A SOLVENT DILUTED TAILINGS TO A DIGESTER DEVICE

摘要

A tailings solvent recovery unit (TSRU) includes a separation apparatusreceivingsolvent diluted tailings including particles and producing solvent componentand solventrecovered tailings component. The separation apparatus may include a flashvessel, atailings outlet, a solvent outlet, and an inlet spray system for supplying thesolventdiluted tailings to the flash vessel. The inlet spray system may include adigester deviceto reduce particle size of particles includes in the solvent diluted tailings,and a nozzlehaving a nozzle diameter and extending within the flashing chamber for flash-atomizingthe solvent diluted tailings.
