Patent number: 7799960Abstract: In a method and apparatus for thermal processing of slurry, the slurry is combined with a bio-mass to produce a mixture which is then subjected to a cracking temperature in a receiving tank, thereby liquefying and allowing the mixture to catalytically undergo a cracking reaction. The cracking reaction which the liquefied mixture undergoes is continued in a mixer pump to thereby produce a reaction mixture. The reaction mixture is outgased in an intermediate tank to separate an outgased fraction from a non-outgased fraction. Subsequently, the outgased fraction is allowed to cool down, thereby producing fuel, while the non-outgased fraction is returned to the receiving tank and subjected again to the cracking temperature. Residual matter of the non-outgased fraction settles in the intermediate tank and is periodically removed.Type: GrantFiled: September 13, 2007Date of Patent: September 21, 2010Inventor: Jürgen Buchert

Patent number: 7534326Abstract: Clamping system and method for clamping the bottom head cover of a coke drum to the bottom flange thereof are disclosed. The system and method include determining the flange stiffness or resistance to deflection resulting from the spring-like force exerted on the bottom head cover and bottom flange gasket seating surface by the gasket in its compressed state. This deflection information may then be used to estimate the minimum number of clamps needed to ensure sufficient load remains on the gasket at the midpoints between the clamps to effectively keep the gasket sealed. An appropriate number of clamps may then be disposed around the periphery of the bottom flange to clamp it to the bottom head cover. In one practical design, each clamp engages a lug attached to the periphery of the bottom head cover such that the clamp does not extend underneath the bottom head cover when clamped.Type: GrantFiled: August 29, 2005Date of Patent: May 19, 2009Assignee: ConocoPhillipcs CompanyInventors: Brian J. Doerksen, Vance C. Green, Jinyang James Lu, Charles Schroeder, Meir Snir, Mohamad T. Ali

Publication number: 20080264771Abstract: A fast pyrolysis apparatus (200) for producing pyrolysis liquid, such as oil or tar, char and pyrolysis gas from biomass, such as straw, comprises a centrifuge chamber (204) and a rotor (210) arranged to impart rotation on the biomass in the centrifuge chamber to force the biomass outwardly under the action of centrifugal forces. A furnace (206) arranged coaxially around the centrifuge chamber (204) maintains the temperature at an outer reactive wall of the centrifuge chamber at an elevated temperature to effect the pyrolysis process at or near the reactive wall. The apparatus comprises a condenser (218) arranged coaxially with and surrounded by the centrifuge chamber (204). The apparatus may be accommodated by a mobile unit for simultaneously collecting biomass from a field and processing the biomass in the apparatus.Type: ApplicationFiled: May 3, 2006Publication date: October 30, 2008Inventors: Kim Dam-Johansen, Niels Bech, Peter.

Publication number: 20080210537Abstract: The invention is a method of separating metals such as zinc, lead and cadmium from iron in secondary feed stocks such as EAF Dust, BOF Sludge, mill scale, iron fines, tire dust and other iron and zinc containing residues and dusts. The method includes the steps of reduction roasting the feed stocks at a volatizing temperature sufficient to volatilize the zinc and other metals into metal fumes but insufficient to volatize iron and then collecting the metal fumes as a metal dust. The metal dust is then leached with a leaching liquid to form a leach liquor and a leach residue. The leach liquor is then purified by zinc dust cementation to form a purified liquor and a zinc dust cement residue. The purified liquor is then separated from the zinc dust cement residue, and a zinc recovery step is then performed on the purified liquor.Type: ApplicationFiled: February 28, 2008Publication date: September 4, 2008Inventor: George Puvvada

Publication number: 20080128259Abstract: Methods and systems for substantially continuously treating comminuted material containing carbon and hydrogen, for example, used tires, are provided. The methods include the steps of introducing the tire material to an elongated chamber, transferring the tire material through the elongated chamber, heating the tire material to a temperature sufficient to pyrolyze the material to produce a gaseous stream; discharging the gaseous stream from the chamber, and cooling at least some of the gaseous stream to liquefy components of the stream. The transfer may be effected by a flexible, center-less screw conveyor to minimize material buildup in the vessel. The cooling of the gaseous stream may be practiced by reverse condensation. One or more re-usable fuel streams are provided by aspects of the invention.Type: ApplicationFiled: November 6, 2007Publication date: June 5, 2008Inventors: Stanislaw Kostek, Stanislaw Kostek

Patent number: 7004999Abstract: A method of continuously capturing BioOil and its constituents from a gas stream produced in a fast pyrolysis/thermolysis process, in a usable liquid form so as to produce a non-condensable gas free of fouling contaminates. The method includes separating BioOil and its constituents from a gas stream using hot inertial separation to maintain the temperature of said BioOil and its constituents above a temperature at which the thick and/or sticky constituents cause inefficient operation of the equipment but low enough so that they do not undergo rapid degradation. Next the gas velocity is reduced to a temperature sufficiently low to allow droplets in the gas stream to settle out but high enough so that a viscosity of said droplets remains low enough to avoid inefficient operation of the separation equipment. Finally, liquid is condensed out of the gas stream.Type: GrantFiled: August 18, 2003Date of Patent: February 28, 2006Assignee: Dynamotive Energy Systems CorporationInventors: Warren L. Johnson, Gholam H. Yavari, Desmond St. A. G. Radelin

Patent number: 6881303Abstract: A plastic as a material to be treated and an additive such as unsaturated fatty acid oil are mixed, and the mixture is heated in a pyrolysis tank at a temperature of 300° C. to 450° C. by a heating member to thereby thermally decompose the mixture. A gas component produced during the heating process is then removed and a pyrolysate is thus produced.Type: GrantFiled: February 28, 2001Date of Patent: April 19, 2005Assignee: Tokyo Ertec Co., Ltd.Inventors: Yoji Inoue, Satoru Aikawa, Norihiro Inagaki, Shigeru Tasaka

Patent number: 6875317Abstract: Wastes mainly containing any one or two or more of raw garbage, waste lumber, paper diapers, waste plastics, and organic sludge discharged from the food industry, common houses, etc. are exposed to high-temperature steam of 510 to 900° C. in an oxygen-free state, preferably while being stirred, to be carbonized. Thereby, the amount of wastes is reduced safely and efficiently with no fear of generating harmful substances such as dioxin, and moreover the carbonized wastes can be reused effectively for applications to fuel or the like.Type: GrantFiled: February 28, 2000Date of Patent: April 5, 2005Inventor: Jiro Toyoda

Patent number: 6875316Abstract: Related to a blast furnace coke and a production method thereof. A coke having high reactivity and high strength in which coke strength, reactivity with CO2 and a pore size distribution are each at a desired level can be produced at a low cost by using a coal blend composed of a small number of brands comprising a large quantity of caking coal having medium rank and low fluidity. The blast furnace coke, being obtained by charging a coal blend comprising 60 wt % or more of semi-heavy caking coal having medium rank and low fluidity in which a content of inert component is 30 vol % or more in total or another coal blend comprising 60 wt % to 95 wt % of semi-heavy caking coal having medium rank and low fluidity in which mean reflectance (Ro) is 0.9 to 1.1 and maximum fluidity (MF) is less than 3.0 and the balance being a caking coal in which mean reflectance (Ro) exceeds 1.Type: GrantFiled: October 19, 2000Date of Patent: April 5, 2005Assignee: JFE Steel CorporationInventors: Koji Hanaoka, Seiji Sakamoto, Katsutoshi Igawa, Yutaka Yamauchi, Shizuki Kasaoka, Toshiro Sawada, Koichi Shinohara, Yuji Tsukihara, Shinjiro Baba
