  • Patent number: 8388813
    Abstract: Improved, fuel-efficient systems are provided for the processing of biomass, such as wood or crop residues, food waste or animal waste in order to selectively obtain torrefied and/or carbonized final products. In general, the processes involve thermally drying incoming biomass using a dryer employing the hot gas output of a fuel-operated burner. Next, the dried product is torrefied in an indirect torrefaction reactor so as to evolve light volatile organic compounds which are used as a gaseous fuel source for the burner. The torrefied product can be recovered, or some or all of the torrefied product may be directed to a carbonization reactor coupled with a reactor burner. Carbonization serves to remove most of the remaining VOCs which are used as a gaseous fuel input to the dryer. In certain instances, portions of the dried biomass are directed to the burners, as an additional source of fuel.

    Abstract: The present invention provides an atomizer for producing finely dispersed spray of slurry/liquid and a process for the preparation of free flowing spray dried alumina powder. The jet-wheel impact atomizer based on the principle of addition of momenta has been invented and developed for spray drying. The atomizer works at significantly low slurry/liquid pressure (1-5 bar) and relatively lower speed (6000-14000 rpm). It saves a considerable amount of energy in view of above two advantages. Suspended solid in liquid is used as the feed slurry which is ejected from a nozzle in the form of a jet to hit against the toothed surface of a rotating wheel to cause atomization. The sprayed droplets are dried inside an associated drying chamber and collected through a screw conveyor at the bottom of the chamber. The feed solid at slurry stage is taken in the form of powder and includes ceramic, inorganic and organic compounds, food, drugs and Ayurvedic products.

  • Publication number: 20100008836
    Abstract: An apparatus for cracking organic substances, for making a mixture of solid and/or liquid and/or gaseous components. The device comprises a cracking chamber (5) with substantially tubular walls arranged between an inlet port (?) of said organic substances and an outlet port (7) of the mixture. In the chamber (5) a rotor shaft is arranged (23) associated with rotary actuating means (24) of the rotor shaft (23) with respect to the walls of the chamber in such a way that the cracking occurs by friction of the substances during the relative rotation between the rotor shaft (23) and the walls of the cracking chamber (5). A feeding device pushes the substances in the cracking chamber (5), where they are subject to a high speed mixing action owing to the rotor shaft (23), and a variable gap (S) adjusts the friction, in particular, in a first tubular section (20) of the chamber (5), so that the transformation temperature reaches a desired value.

    Abstract: A reactor is provided for converting organic material to charcoal, with the reactor having a furnace and a retort extending through the furnace. The retort has an auger extending therethrough, with the auger having a flight with gaps therein. Members project inwardly from the walls of the retort at the gaps in the flight to unplug blockages in the retort. A gas collection system is provided which has a branched portion having two or more venting tubes, each with valves so that each may be shut off independently to allow to off-line cleaning without requiring shutdown of the system. A method for converting organic material may be practiced by introducing combustible materials into the reactor.

  • Patent number: 7507385
    Abstract: Process for the catalytic dehydrogenation of a C2 or C3 alkyl aromatic in which a feedstock containing the alkyl aromatic and steam is supplied into the inlet of a tubular reactor containing a dehydrogenation catalyst. Within the reactor, the feedstock flows through at least a portion of the reactor along a spiral flow path extending longitudinally of the reactor. The resulting vinyl aromatic product is then recovered from a downstream or outlet section of the reactor. The spiral flow path through which the feedstock is passed is located at least adjacent the inlet side of the reactor and at least a portion of the spiral flow path contains a particulate dehydrogenation catalyst. The spiral flow path may extend throughout a major portion of the elongated tubular reactor and may contain a particulate dehydrogenation catalyst in a substantial portion there.

  • Patent number: 7169292
    Abstract: The present invention provides a pyrolysis tube for enhancing the yield of olefins and reducing a coking tendency in steam cracking of hydrocarbons. According to the present invention, the pyrolysis tube is characterized in that a plurality of mixing blades made by twisting two ends of a plate in opposite directions are included therein. The yield of ethylene is thereby improved and the coking tendency is reduced by mixing a fluid flow, improving a heat transfer rate and shortening a residence time of the reactants therein.

  • Patent number: 7169960
    Abstract: A process for the dehydrogenation of a C2 or C3 alkyl aromatic compound to a corresponding vinyl aromatic compound in a tubular reactor incorporating a spiral flow path. Preferred embodiments of the invention provide processes for the production of styrene or divinylbenzene by the catalytic dehydrogenation of ethylbenzene or diethylbenzene, respectively. A feedstock containing a C2 or C3 alkyl aromatic and steam is supplied into the inlet of a tubular reactor containing a dehydrogenation catalyst and comprising a hydrogen permeable outer wall. The alkyl aromatic compound is dehydrogenated to a corresponding vinyl aromatic compound with the attendant production of hydrogen. The feedstock and products of the dehydrogenation reactor are flowed along a longitudinal spiral flow path providing for an outward radial flow of hydrogen to provide a pressure gradient through the hydrogen permeable outer wall of the reactor with the flow of hydrogen therethrough. Hydrogen is removed from the outer wall of the reactor.

  • Patent number: 7153480
    Abstract: A reactor for the oxidation of a precursor to an aromatic carboxylic acid or ester thereof in a liquid phase reaction mixture is disclosed. The reactor comprises an elongate vessel, substantially vertical in use, having an upper mixing element and a lower mixing element, characterised in that the upper mixing element is an axial pumping impeller and the lower mixing element is a radial pumping impeller. A process of producing a carboxylic acid or ester thereof in a reactor of the invention is also disclosed. In use, the configuration of mixing elements leads to three highly turbulent mixing zones. In a preferred embodiment of the process of the present invention oxidant, from one inlet, and solvent, precursor and catalyst, are introduced directly into a mixing zone. The highly turbulent mixing zones lead to rapid mass transfer suppressing the formation of unwanted, coloured by-products and reduced reactor fouling.

  • Patent number: 7081233
    Abstract: A vessel is mounted external to a liquid sulfur storage pit for degassing liquid sulfur at atmospheric pressure. Liquid sulfur is re-circulated from the pit to a static mixing device extending from a head space to the liquid sulfur which provides intimate contact of the liquid sulfur as it flows downwardly and sweep air flowing through the head space above the pit. Further, the static mixing device prevents free fall of liquid sulfur and the hazards of static electricity associated therewith. Use of a heat traced gas outlet induces flow of sweep gas from the system, obviating the need for a steam eductor or blower.
