20090000906 | APPARATUS FOR RECOVERING POWER FROM FCC PRODUCT - Disclosed is an apparatus for recovery power from an FCC product. Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors. | 01-01-2009 |
20090000987 | PROCESS FOR RECOVERING POWER FROM FCC PRODUCT - Disclosed is a process for recovery power from an FCC product. Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors. | 01-01-2009 |
20090065394 | Hydrocracking process for fabricating distillate from fisher-tropsch waxes - A method for obtaining a petroleum distillate product is provided, the method includes subjecting a Fischer-Tropsch wax to a process of hydrocraking carried out at a pressure which is substantially lower that the pressure previously used. A catalyst including a noble metal is used in this method. An apparatus for carrying out the method is also provided. | 03-12-2009 |
20090065401 | ATMOSPHERIC FRACTIONATION FOR HYDROCRACKING PROCESS - In an atmospheric fractionator, the number of theoretical stages are increased in the upper light distillate flash zone and in the middle heavy distillate flash zone. The middle distillate pumparound circuit has been eliminated. The reflux to distillate ratio for the light distillate as well as the effluent feed temperature have been substantially increased. As a result, increased yields for middle distillate (e.g. kerosene) and heavy distillate (eg diesel) have been achieved which more than offset the increased energy consumption used for the higher feed temperature In the example of hydrocracking technology, the improved fractionation has benefits in the hydrocracking unit outside of the fractionation unit Increased fractionation efficiency reduces the severity in the hydrocracking unit reactor catalyst and less hydrogen is consumed. The invention can be applied to several other refining technologies besides hydrocracking. | 03-12-2009 |
20100133144 | PRODUCTION OF FUEL FROM RENEWABLE FEEDSTOCKS USING A FINISHING REACTOR - A process has been developed for producing fuel from renewable feedstocks such as plant and animal oils and greases. The process involves treating a first portion of a renewable feedstock by hydrogenating and deoxygenating in a first reaction zone and a second portion of a renewable feedstock by hydrogenating and deoxygenating in a second reaction zone and treating the effluents in a finishing reaction zone to provide a diesel boiling point range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the first reaction zone to increase the hydrogen solubility of the reaction mixture. | 06-03-2010 |

Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors. | 12-16-2010 |
20100326884 | METHOD FOR MULTI-STAGED HYDROPROCESSING - Methods for processing a hydrocarbonaceous feedstock flows are provided. In one aspect, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. A hydrogen source is provided substantially free of hydrogen from a hydrogen recycle compressor. The hydrocarbonaceous feedstock flow is separated into an portions of fresh feed for each hydroprocessing stage, and the first portion of fresh feed to the first hydroprocessing stage is heated. The heated first portion of fresh feed is supplied with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. The unheated second portion of fresh feed is admixed with effluent from previous stage to quench the hot reactor effluent before entering a second stage. | 12-30-2010 |
