ABSTRACT:
A system and process for concentrating hydrocarbons in a bitumen feed comprising bitumen, water and solids. The system comprises an inclined plate separator, a hydrocarbon cyclone and a centrifuge. The inclined plate separator separates the bitumen feed into a first overflow stream and a first underflow stream, the first overflow stream having a first bitumen concentration greater than that of the first underflow stream. The hydrocarbon cyclone separates the first underflow stream into a second overflow stream and a second underflow stream. The centrifuge separates the second overflow stream into a third overflow stream and a third underflow stream, the third overflow stream having a third bitumen concentration that is greater than that of the third underflow stream.
