METHOD FOR REDUCING RAG LAYER VOLUME IN STATIONARY FROTH TREATMENT
A method for reducing rag layer volume in a stationary bitumen froth treatment process is provided, comprising subjecting dilfroth having a naphtha diluent to bitumen ratio of about 0.7 to gravity settling in a splitter vessel to produce an overflow stream of raw dilbit and an underflow stream of sp...

| description | A method for reducing rag layer volume in a stationary bitumen froth treatment process is provided, comprising subjecting dilfroth having a naphtha diluent to bitumen ratio of about 0.7 to gravity settling in a splitter vessel to produce an overflow stream of raw dilbit and an underflow stream of splitter tails; mixing the splitter tails with a naphtha diluent to give a mixture having a naphtha diluent to bitumen ratio of less than about 6:1 in a scrubber feed tank; and subjecting the mixture to gravity settling and agitation in a scrubber vessel to produce an overhead stream of scrubber hydrocarbons and an underflow stream of scrubber tails. |
