20090127161 | Process and Apparatus for Integrated Heavy Oil Upgrading - A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked to produce vacuum gas oil (VGO). A light portion of the VGO may be hydrotreated and subjected to fluid catalytic cracking to produce fuels such as gasoline. A heavy portion of the VGO may be recycled to the slurry hydrocracking reactor. FCC slurry oil may be recycled to the slurry for hydrocracking. | 05-21-2009 |

20090155139 | Apparatus for Crystallizing Polymer Particles - The present invention is a process and apparatus for conserving loss of heat while forming and crystallizing polymer particles in a liquid. The cooling liquid quenches the polymer during particle molding to facilitate shaping. The cooling liquid cools the polymer particles not below a temperature that allows adequate crystallization to occur. Cooling liquid is quickly switched with a warming liquid, so the temperature of the polymer is in the crystallization range and the heat of crystallization self-heats the polymer to a higher temperature. | 06-18-2009 |
20100034710 | Residual Oil Coking Scheme - A coking process and apparatus may include cracking a hydrocarbon feed stream with a catalyst, generating a hot flue gas from regenerating said catalyst, directing the hot flue gas into a spray contactor, spraying a heavy residual oil into the spray contactor, and coking the heavy residual oil utilizing the hot flue gas as a heat source. The hydrocarbon feed stream and the heavy residual oil may each or both be generated by a solvent deasphalter. The coking process produces a solid coke product and volatile hydrocarbons which leave with the hot gas and may be burned in an oxidizer to generate steam with the pressure energy recovered by a turbo-expander. | 02-11-2010 |
20100326882 | PITCH COMPOSITION - A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together. | 12-30-2010 |

20110139676 | COMPOSITION OF HYDROCARBON FUEL - Slurry hydrocracking a heavy hydrocarbon feed produces a HVGO stream and a pitch stream. At least a portion of the pitch stream is subjected to SDA to prepare a DAO stream low in metals. The DAO is blended with at least a portion of the HVGO stream to provide turbine or marine fuel with acceptable properties for combustion in gas turbines or for marine fuel grades. | 06-16-2011 |
