Non-aqueous solvent extraction of bitumen from oil sands has the potential to replace the existing hot-water extraction process. The benefit of non-aqueous extraction process includes high bitumen recovery, reduction of fresh water demand for extraction and the elimination of resulting tailing...
Solvents are ubiquitously used in oil sands extraction industry to enhance the separation of bitumen froth. With developing new technologies such as non-aqueous bitumen extraction, the need to track solvent interactions with oil sands components throughout the extraction process and to identify...
