In the present article, deasphalting of bitumen with low-molecular oxygen containing solvents was proposed. A method for regulating the process of deasphalting aimed at increasing the yield of low-viscosity deasphalted oil was developed. The influence of the depth of distillation and solvent: feed ratio on the yield of the products of deasphalting was revealed. A study on various technological options for the primary processing of natural bitumen and ultra-high-viscosity oils for pipeline transport was conducted.
