  • Method for high-temperature short-time distillation of residual oils
    Patent number: 6413415
    Abstract: High temperature flash distillation, for treating residual oils originating from crude oil refining, natural bitumen and/or tar sands, comprises feeding the oil to a mixer with granular hot coke, which serves as a thermal transfer medium. In mixing, 60-90% of the oil is vaporized. The non-vaporized fraction includes metal-containing asphaltenes. This fraction is further converted in the mixer, to oil vapor, gas and coke. Gases and vapor are withdrawn from the mixer, separately from the coke. The vapor phase is cooled and condensed to produce product oil. The gas itself is a further product. The coke is reheated and recycled to the mixer as the thermal transfer medium.
