Hydrocarbon Gas Conversion System And Process For Producing A Synthetic Hydrocarbon Liquid
US Patent:
6130259, Oct 10, 2000
Filed:
Aug 18, 1998
Appl. No.:
9/135821
Inventors:
John J. Waycuilis - Cypress TX
Assignee:
Marathon Oil Company - Findlay OH
International Classification:
C07C 2706
US Classification:
518703
Abstract:
A system and process are provided for converting a light hydrocarbon gas to a synthetic heavier hydrocarbon liquid. The system includes an autothermal reformer, a Fischer-Tropsch reactor and a Brayton cycle that are structurally and functionally integrated. In the practice of the process, a mixture of a hydrocarbon feed gas, a compressed air feed and process steam is fed to the autothermal reformer to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The tail gas is heated and fed with compressed air and steam to the Brayton cycle having a combustor and a series of power turbines and compressors.
Staged Combustion Of A Low Heating Value Fuel Gas For Driving A Gas Turbine
US Patent:
6201029, Mar 13, 2001
Filed:
Sep 10, 1998
Appl. No.:
9/150865
Inventors:
John J. Waycuilis - Cypress TX
Assignee:
Marathon Oil Company - Findlay OH
International Classification:
C07C 2700
US Classification:
518703
Abstract:
A process is provided for combusting a low heating value fuel gas in a combustor to drive an associated gas turbine. A low heating value fuel gas feed is divided into a burner portion and a combustion chamber portion. The combustion chamber portion and a combustion air are conveyed into a mixing zone of the combustor to form an air/fuel mixture. The burner portion is conveyed into a flame zone of the combustor through a burner nozzle while a first portion of the air/fuel mixture is conveyed into the flame zone through a burner port adjacent to the burner nozzle. The burner portion and first portion of the air/fuel mixture are contacted in the flame zone to combust the portions and produce flame zone products. The flame zone products are conveyed into an oxidation zone of the combustor downstream of the flame zone while a second portion of the air/fuel mixture is also conveyed into the oxidation zone. The second portion is combusted in the oxidation zone in the presence of the flame zone products to produce combustion products.

Filed:
Apr 8, 2005
Appl. No.:
11/101886
Inventors:
John J. Waycuilis - Cypress TX, US
Assignee:
Marathon Oil Company - Houston TX
International Classification:
C07C 1/00
US Classification:
585408, 585359, 585469, 585642, 585733
Abstract:
A process for converting gaseous alkanes to liquid hydrocarbons wherein a gaseous feed containing alkanes is reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid are then reacted over a synthetic crystalline alumino-silicate catalyst, such as a ZSM-5 zeolite, at a temperature of from about 150° C. to about 450° C. so as to form higher molecular weight hydrocarbons and hydrobromic acid vapor. Propane and butane which comprise a portion of the products may be recovered or recycled back through the process to form additional C+ hydrocarbons. Various methods are disclosed to remove the hydrobromic acid vapor from the higher molecular weight hydrocarbons and to generate bromine from the hydrobromic acid for use in the process.

Formation Of A Stable Wax Slurry From A Fischer-Tropsch Reactor Effluent
US Patent:
6313361, Nov 6, 2001
Filed:
Aug 18, 1998
Appl. No.:
9/135625
Inventors:
John J. Waycuilis - Cypress TX
Assignee:
Marathon Oil Company - Findlay OH
International Classification:
C07C 200, C07C 2700
US Classification:
585314
Abstract:
A process is provided for treating a liquid effluent from a gas to liquid conversion reactor. A synthesis gas is initially converted to a liquid hydrocarbon phase in the gas to liquid conversion reactor. The liquid hydrocarbon phase includes a heavier liquid paraffinic wax compound and a lighter liquid paraffinic compound. The liquid hydrocarbon phase is discharged from the gas to liquid conversion reactor in a reactor effluent and an abrasive solid particle medium is entrained in the reactor effluent to form a fluidizable mixture. The reactor effluent is conveyed past a heat transfer surface which is cooler than the reactor effluent. The fluidizable mixture is contacted with the heat transfer surface and the liquid hydrocarbon phase is cooled to a temperature below the melting point of the heavier liquid paraffinic wax compound. Consequently, the heavier liquid paraffinic wax compound is converted to a plurality of unconsolidated solid wax particles. A slurry is formed from the plurality of unconsolidated solid wax particles and the remaining lighter liquid paraffinic compound.
