  • Patent number: 8092671
    Abstract: A method is disclosed for treating gaseous effluent from a hydrocarbon pyrolysis unit to provide steam cracked tar of reduced asphaltene and toluene insolubles content. The method is suitable for preparing reduced viscosity tar useful as a fuel blending stock, or feedstock for producing carbon black, while reducing or eliminating the need for externally sourced lighter aromatics additives to meet viscosity specifications. The method comprises drawing steam cracked tar from a separation vessel, e.g., a primary fractionator or tar knock-out drum, cooling the tar, and returning it to the separation vessel to effect lower overall tar temperatures within the separation vessel, in order to reduce viscosity increasing condensation reactions. An apparatus for carrying out the method is also provided.

  • Patent number: 8062506
    Abstract: An FCC process comprising an enlarged riser section and a distributor in an elevated position and with an opening in its tip away from riser walls may reduce coke build-up along the interior walls of a riser. Catalytic mixing may be improved, which could reduce riser coking by increasing hydrocarbon contact with catalyst before contacting the riser wall. Increasing the distance between the introduction of the hydrocarbon and the riser wall may increase this likelihood for hydrocarbon-catalyst contact. Highly contaminated hydrocarbons cause greater coking than do normal hydrocarbons and this FCC process may be effective in decreasing riser coking on such heavy hydrocarbons.

  • Patent number: 8062483
    Abstract: Crude chlorosilane streams containing lower-boiling chlorosilanes and higher-boiling chlorosilanes are separated by contacting them with a distillation aid. The lower-boiling chlorosilanes are separated from the crude chlorosilane stream, and then the distillation aid and the higher-boiling chlorosilanes are separated from one another. The distillation aid is a mono-cyano-substituted organic compound, a nitro-substituted organic compound, a mono-cyano-substituted organosilicon compound, a nitro-substituted organosilicon compound, or a mixture thereof. These distillation aids increase the relative volatility of crude chlorosilane streams such as methyltrichlorosilane and dimethyldichlorosilane resulting in improved separation at lower capital and/or fixed costs.
