  • Patent number: 7947858
    Abstract: In a method and apparatus for thermal processing of catalytically active biomass, the biomass is subjected in a receiving tank to a cracking temperature to undergo a cracking reaction. The biomass is transferred to a mixer pump to produce a reaction mixture which is directed into an outgassing chamber of an intermediate tank to produce an outgassed fraction and a non-outgassed liquid fraction. The outgassed fraction to produce fuel is cooled down, and a first portion of the non-outgassed liquid fraction is returned and subjected again to the cracking temperature in the receiving tank. A second portion of the non-outgassed liquid fraction is conducted in a bypass to the outgassing chamber of the intermediate tank for outgassing while fresh biomass is added. Residual matter settling in the intermediate tank is periodically removed.

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.

  • Patent number: 7037410
    Abstract: An improved process and apparatus for the destructive distillation or pyrolysis of rubber, such as used rubber tires, to produce liquid and gaseous hydrocarbons and a solid carbonaceous char. A heat transfer gas circulating in a circulation loop is used to cool the hot char produced in the distillation chamber of a distillation oven, the circulation loop having some means for removing the heat transferred to the heat transfer gas from the hot char. In one embodiment, two distillation ovens are operated in off-set, batchwise distillation cycles. The distillation cycles in the two ovens are coordinated so that a fresh charge of rubber feed is introduced into the distillation chamber of one of the ovens as the distillation of rubber in the other oven is concluded.

  • Patent number: 6797122
    Abstract: A coke oven and a method of operating the same, capable not only of achieving a uniform combustion temperature heightwise within a combustion chamber when a rich gas or a lean gas is burnt, but also of reducing NOx content in the waste gas, while eliminating localized high-temperature combustion. The combustion chamber of the coke oven comprises a rich-gas port 2 located near an oven wall 6 bordering a carbonization chamber in the bottom 5 of combustion chamber, and the midpoint P3, connecting the center P2 of a lean-gas port 7 and the center P of an air port 3, is on the side opposite to the rich-gas port 2 relative to the center line CL of the combustion chamber.

  • Patent number: 6764592
    Abstract: A method of producing petroleum coke in a petroleum coking system comprising the steps of (a) adding a fluid to a live coking drum while warming a second drum so that additional vapor is provided in the live drum and (b) reducing pressure loss in the live drum by regulating the addition of the fluid based upon a target pressure for the live drum and by regulating the flow of warm-up vapor from the live drum to the second drum based upon a target pressure for the second drum. The flow of warm-up vapor from the live drum to the second drum is preferably conducted via a conduit system having a total length of less than 100 feet.

    Abstract: The present invention concerns a processing furnace used by the oil industry to heat feedstocks that are to be treated thermally, which is provided with bi-pivotal support columns to carry the radiation exchange tubes which form the coil of radiation exchange tubes. The support columns are provided with a lower bearing and an upper bearing means, which pivot, respectively, on a lower support and an upper guide, in such a way that all the stresses from the support and the radiation exchange tubes are transmitted to the base, causing no thermal stress from bending momentum to be transmitted to the base of the furnace.

  • Publication number: 20030213687
    Abstract: A cracking furnace for the pyrolysis heating of an organic feedstock includes a heating section and at least one convection section. In one embodiment the furnace includes first and second convection sections positioned along opposite sides of the heating section. The openings for admitting flue gas to the convection sections can be at the top or the bottom of the heating section. In another embodiment the furnace includes a plurality of passageways for the communication of flue gas from the heating section to the convection section. The passageways can be positioned at the top or the bottom of the heating section. The passageways provide a more even flow of flue gas through the heating section by preventing recirculation of the flue gas within the heating chamber.

  • Patent number: 6596128
    Abstract: 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.
