Patent number: 6596128Abstract: The invention provides a method and apparatus for decreasing gas flow rates in a sole flue gas system for a coke oven during at least an initial coking operation after charging a coking oven with coal. The method includes providing a duct system between a first coke oven having a first coking chamber and a second coke oven having a second coking chamber to direct at least a portion of gas from a gas space in first coking chamber to the second coke oven thereby reducing a gas flow rate in the first sole flue gas system of the first coke oven. Reduction in sole flue gas flow rates has a beneficial effect on product throughput, the life of the coke oven and environmental control of volatile emissions from coke ovens.Type: GrantFiled: February 14, 2001Date of Patent: July 22, 2003Assignee: Sun Coke CompanyInventor: Richard W.

Patent number: 6193848Abstract: A pressure-tight vessel subjected to severe thermal cycling through a temperature range including temperatures up to in excess of approximately 700° F. Unlike conventional pressure-tight vessels that are constructed of plates arranged horizontally, the vessel is built of plates that are greater than sixteen feet high. As a result, there are no circumferential seams in a critical area of the cylindrical section of the vessel, providing superior durability.Type: GrantFiled: December 9, 1998Date of Patent: February 27, 2001Assignee: Chicago Bridge & Iron CompanyInventors: Lestle R.

Patent number: 6013158Abstract: An apparatus for forming liquid hydrocarbons from solid coal. The coal is pulverized to provide a particulate coal feed, which is then extruded to provide a hollow tube of compressed coal supported inside of a support tube. A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube. The temperature of combustion is sufficient to fire the extruded clay and pyrolyze the extruded coal to produce hydrocarbon gases and coal char. The support tube has holes for releasing the hydrocarbon gases, which contain suspended particles formed during combustion. The suspended particles are removed from the hydrocarbon gases to provide clean gases, which are passed through an ionizing chamber to ionize at least a portion thereof. The ionized gases are then passed through a magnetic field to separate them from each other according to their molecular weight.Type: GrantFiled: March 30, 1999Date of Patent: January 11, 2000Inventor: William A.

Patent number: 4925532Abstract: A method and apparatus for the thermal conversion of organic waste materials includes a tank having a molten metal bath, preferably lead, through which apertured containers are transported by primary conveyer members in a plane intermediate two arrays of heating devices. Buoyancy of the waste-filled containers is resisted by abutment members within the tank while alignment elements on the containers prevent the containers from becoming askew during their travel through the tank. The abutment members may comprise fixed rails or secondary coveyor members spaced atop the primary conveyor members. Agitation devices within the tank assist in maintaining maximum heat distribution throughout the bath. Produced hydrocarbons are collected by a main hood overlying the major portion of the tank bath surface while separate shroud assemblies overlie other, individual isolated bath surfaces at the entrance and exit of the tank.Type: GrantFiled: April 24, 1989Date of Patent: May 15, 1990Assignee: PTO, Inc.Inventors: William E.
