A METHOD FOR IMPROVING PARAFFINIC FROTH TREATMENT PROCESS IN OIL SANDS EXTRACTION

摘要

An unfiltered paraffinic froth treatment (PFT) process. A method for improving a paraffinic froth treatment (PFT) process in oil sands extraction includes identifying a flow path from a bitumen froth storage tank outlet, through a froth feed pump flow passage, a mixer flow passage, a debris filter flow passage, and a froth settling unit flow passage, to a tailings solvent recovery unit inlet passage, identifying a minimum flow passage size in the flow path, excluding the debris filter flow passage, and enlarging the flow path to at least the minimum flow passage size, and removing the debris filter from the flow path, wherein a filterless PFT process is provided.
