Investigations of nonaqueous extraction (NAE) of bitumen from minable oil sands have been extensively revisited in the past decade as an alternative to Clark hot water extraction (CHWE). Significant advances have been achieved in understanding NAE processes at bench and pilot scales, although many questions remain regarding the commercialization of NAE. This critical review summarizes recent research findings and progress on fundamental and practical aspects associated with novel extraction processes, focusing on the technological method, solvent selection, recovery of solvent, and removal of fines. The review also identifies opportunities and challenges for bitumen recovery from oil sands using nonaqueous processes.
