  • Patent number: 8840777
    Abstract: A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a non-acidic metal-containing catalyst at a temperature of 375° C. to 500° C. to produce a vapor comprising a first hydrocarbon-containing product. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal at a temperature of 260° C.-425° C. to produce a second hydrocarbon-containing product. The second hydrocarbon-containing product is separated into fractions, one of the fractions being a heavy hydrocarbon fraction comprised of hydrocarbons having a boiling point of at least 343° C. The heavy hydrocarbon fraction is then contacted with a fluidizable cracking catalyst at a temperature of at least 500° C.

  • Patent number: 8784648
    Abstract: A method is provided for producing vacuum in a vacuum oil-stock distillation column and includes pumping a gas-vapor medium out of a column by an ejector into a condenser; feeding a gas mixture and a high-pressure gas into a second gas-gas ejector from which the vapor-gas mixture is fed into a second condenser. A condensate is directed from the condensers into a separator in which the condensate is separated into a water-containing condensate and a hydrocarbon-containing condensate. The hydrocarbon-containing condensate is removed while the water-containing condensate is fed into a steam generator in which heat is supplied to the water-containing condensate from a hot distillate removed from the vacuum column and steam is produced from the water-containing condensate, the steam is fed as a high-pressure gas into the gas-gas ejectors. A plant for carrying out the method is also provided.

  • Patent number: 8709237
    Abstract: A process for treating bitumen froth with paraffinic solvent is provided which uses three stages of separation. Froth and a first solvent are directed to a first stage at a solvent/bitumen ratio for precipitating few or substantially no asphaltenes. A first stage underflow is directed to a second stage and a first stage overflow is directed to a third stage. A second stage underflow is directed to waste tailings and the second stage overflow joins the first stage overflow. A third stage underflow is recovered as an asphaltene by-product and a third stage overflow is recovered as a diluted bitumen product. At least a second solvent is added to one or both of the second or third stages for controlling a fraction of asphaltenes in the third stage underflow. Asphaltene loss to waste tailings is minimized and asphaltenes are now recovered as asphaltene by-product.
