Get PriceIt is demonstrated that bitumen can be separated from “waterwet” Alberta oil sands and “oilwet” Utah oil sands using a socalled analogue ionic liquid (IL) based on deep eutectic mixtures of choline chloride and urea (ChCl/U) together with a diluent such as naphtha. Unlike conventional ILs, these eutectics are relatively cheap and environmentally friendly.
