摘要： In the field of oil sands processing, a process for heating an oil sands slurry stream such as bitumen froth containing bitumen and water and having variable heating requirements includes injecting steam directly into the froth at a steam pressure through a plurality of nozzles to achieve sonic steam flow; operating the plurality of the nozzles to vary steam injection by varying a number of the nozzles through which the injecting of the steam occurs in response to the variable heating requirements; and subjecting the oil sands slurry stream to backpressure sufficient to enable sub-cooling relative to the boiling point of water. A corresponding system is also provided.
