20090112030METHOD FOR OLEFIN PRODUCTION FROM BUTANES - Systems and processes for producing one or more olefins are provided. In one or more embodiments, a C04-30-2009
20090112031METHOD FOR OLEFIN PRODUCTION FROM BUTANES USING A CATALYST - Systems and processes for producing one or more olefins are provided. In one or more embodiments, a feed stream containing butane can be dehydrogenated to provide a first product containing butene. At least a portion of the first product can bypass an existing etherification reactor used for converting isobutylene to MTBE. At least a portion of the first product can be cracked using a catalytic cracker at conditions favoring the conversion of the first product to propylene to provide a second product containing propylene, ethylene, and butane. In one or more embodiments, a catalyst consisting of essentially a zeolite favoring the production of propylene can be used in the catalytic cracker.04-30-2009
20090112032METHOD FOR OLEFIN PRODUCTION FROM BUTANES AND CRACKING REFINERY HYDROCARBONS - Systems and processes for producing one or more olefins are provided. A feed comprising butane can be dehydrogenated to provide a first product comprising butene. The first product can bypass an etherification reactor for converting isobutylene to methyl tert-butyl, and at least a portion of the first product can be cracked in a first cracking zone and fractionated to provide an olefinic mixture comprising propylene, ethylene, and butane. A refinery hydrocarbon comprising gas oil, full range gas oil, resid, or a combination thereof can be cracked in a second cracking zone and quenched to provide a quenched hydrocarbon. The olefinic mixture and the quenched hydrocarbon can be combined and selectively separated to provide a propylene product and a butane recycle.04-30-2009
20090112038METHOD FOR OLEFIN PRODUCTION FROM BUTANES USING ONE OR MORE RISERS - Systems and processes for producing one or more olefins are provided. A feed containing butane can be dehydrogenated to provide a first product containing butene. A refinery hydrocarbon can be cracked in a first riser of a fluidized catalytic cracker to provide a first effluent comprising ethylene, propylene, or a combination thereof. The first product can bypass an etherification reactor for converting isobutylene to methyl tert-butyl ether, and can be cracked in a second riser of the fluidized catalytic cracker to provide a second effluent comprising propylene, ethylene, and butane. The first and second effluents can be combined to provide a second product comprising ethylene, propylene, or a combination thereof, wherein the conditions in the first and second riser are independently selected to favor production of ethylene, propylene, or any combination thereof.04-30-2009
20090112039METHOD FOR OLEFIN PRODUCTION FROM BUTANES AND CRACKING REFINERY HYDROCARBONS AND ALKANES - Systems and processes for producing one or more olefins are provided. A feed containing C04-30-2009

20080230442Process for Upgrading Heavy Oil and Bitumen - Disclosed is a process for the upgrading and demetallizing of heavy oils and bitumens. A crude heavy oil and/or bitumen feed is supplied to a solvent extraction process 09-25-2008
20090166253PROCESS FOR UPGRADING ATMOSPHERIC RESIDUES - Systems and methods for processing one or more hydrocarbons are provided. One or more hydrocarbon feedstocks can be selectively separated to provide one or more light deasphalted oils. At least a portion of the light deasphalted oil can be hydrocracked to provide one or more hydrocarbon products.07-02-2009

20100217059Process for Recovering Ethylene From an Autothermal Cracking Reactor Effluent - The process of this invention represents an improved, low-energy method for recovering a purified ethylene product from the effluent of an autothermal cracking reactor. The process consists of a cracked gas chilling train, a front-end ethylene distributor, a demethanizer, and a C2 splitter. Hydrocarbons heavier than ethylene, including ethane, propylene, and propane are recycled in a single stream to the ATC reactor. Acetylene removal from the ethylene product can be accomplished either through a front-end hydrogenation unit or an acetylene extraction unit. This invention is particularly useful when the fresh hydrocarbon feed to the autothermal cracking reactor is ethane or a mixture of ethane and propane.08-26-2010

20090112037Process for Recovering Ethylene From an Autothermal Cracking Reactor Effluent - The process of this invention represents an improved method for recovering a purified ethylene product and optionally a purified hydrogen product from the effluent of an autothermal cracking reactor. The process consists of cracked gas chilling, rough separation of a hydrogen-rich stream, demethanization, separation of ethylene from the demethanizer bottoms product, and final purification of the ethylene product. Hydrocarbons heavier than ethylene, including ethane, propylene, and propane are recycled to the ATC reactor. Optionally a purified hydrogen product can be obtained from the hydrogen-rich stream. The invention is particularly useful when the fresh hydrocarbons feed to the autothermal cracking reactor is ethane or a mixture of ethane and propane.04-30-2009
20090193846Recovery of Carbon Monoxide and Hydrogen From Hydrocarbon Streams - A process is described for the recovery of CO and optionally hydrogen from a stream containing CO, H2, methane, and hydrocarbons heavier than methane. The process is characterized by a two-stage removal (08-06-2009
