HOT WATER BITUMEN EXTRACTION PROCESS

摘要

This invention relates to a hot water extraction process for removing bitumen oils from ‎tar-sands ore and more particularly to a process combing solvent and hot water extraction ‎with air exclusion, the tar-sands ore is conditioned in hot water and then extracted with a ‎water immiscible hydrocarbon solvent to form a mixture which settles into several ‎phases.‎ Each of these phases is thereafter processed to produce product bitumen oils and recycled ‎process components.‎
