20090170964 | MEMBRANE REACTOR WITH IN-SITU DEHYDRATION AND METHOD FOR USING THE SAME - A fixed bed membrane reactor is disclosed. The reactor has a housing including an inlet for receiving reactants and an outlet for discharging retentate streams of reaction products. The inlet and outlet are in fluid communication with a reaction zone in which the reactants may passe downstream from the inlet to the outlet with the reactants reacting to produce reaction products including water. The reactor further includes a membrane assembly disposed in fluid communication with the reaction zone. The membrane assembly includes at least one porous support with a water permselective membrane affixed thereto. The membrane allows water produced in the reaction zone to be selectively removed from the reaction zone as a permeate stream while allowing retentate reaction products to remain in the reaction zone and be discharged as a retentate stream. Ideally, the membrane assembly locates most of the membrane proximate the downstream portion of the reaction zone where accumulated produced water may be selectively removed from the reaction product as opposed to the upstream portion where relatively little water accumulation has occurred. A method for using the reactor to perform in situ water dehydration of reactions, such as Fischer-Tropsch reaction, is also disclosed. | 07-02-2009 |
20090170965 | ACETYLENE ENHANCED CONVERSION OF SYNGAS TO FISCHER-TROPSCH HYDROCARBON PRODUCTS - A method is disclosed for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products. A synthesis gas including carbon monoxide and hydrogen gas is provided to a F-T reactor. Also, acetylene is supplied to the F-T reactor. The ratio of the volume of acetylene to the volume of synthesis gas is at least 0.01. The synthesis gas and acetylene are reacted under suitable reaction conditions and in the presence of a catalyst to produce F-T hydrocarbon products. The F-T hydrocarbon products are then recovered from the reactor. The synthesis gas and acetylene may be provided in a combined feed stream or introduced separately into the reactor. The acetylene enhanced syngas conversion in a F-T reactor results in the synthesis of F-T products which have a tighter distribution of intermediate length carbon products than do F-T products synthesized according to conventional methods. | 07-02-2009 |
20110240288 | PROCESS AND SYSTEM FOR BLENDING SYNTHETIC AND NATURAL CRUDE OILS DERIVED FROM OFFSHORE PRODUCED FLUIDS - A process and system are described for the processing of gas associated with crude oil production, i.e. associated gas. A separation complex is used to separate produced fluids produced from a hydrocarbon reservoir into crude oil, liquefied petroleum gas, water, and natural gas. At least a portion of the natural gas is converted into synthesis gas in a synthesis gas generator. A combination of a synthesis gas conversion catalysts and hydroconversion catalysts are used in a synthesis gas reactor to convert the synthesis gas into a liquid effluent stream containing liquefied petroleum gas and a synthetic crude oil. The liquefied petroleum gas and synthetic crude oil from the synthesis gas reactor is sent to the separation complex. Liquefied petroleum gas is separated both from the synthetic crude oil and a natural crude oil obtained from the produced fluids. The system and process permits synthetic crude oil to be blended with the natural crude oil producing a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil and with a pour point of 60° C. or less. Use of a common facility for separation operations on the natural crude oil and synthetic crude oil thus reduces capital costs and allows converted associated gases to be shipped with the natural crude oil on a conventional crude oil tanker. | 10-06-2011 |
20110294653 | Fabrication of Catalyzed Ion Transport Membrane Systems - Process for fabricating a catalyzed ion transport membrane (ITM). In one embodiment, an uncatalyzed ITM is (a) contacted with a non-reducing gaseous stream while heating to a temperature and for a time period sufficient to provide an ITM possessing anion mobility; (b) contacted with a reducing gaseous stream for a time period sufficient to provide an ITM having anion mobility and essentially constant oxygen stoichiometry; (c) cooled while contacting the ITM with the reducing gaseous stream to provide an ITM having essentially constant oxygen stoichiometry and no anion mobility; and (d) treated by applying catalyst to at least one of (1) a porous mixed conducting multicomponent metallic oxide (MCMO) layer contiguous with a first side of a dense layer of MCMO and (2) a second side of the dense MCMO layer. In another embodiment, these steps are carried out in the alternative order of (a), (d), (b), and (c). | 12-01-2011 |
