  • Patent number: 8968574
    Abstract: A method and device for the wet oxidation treatment of liquid waste laden with mineral matter in suspension. The device comprises a reactor including a treatment column, first and second heat exchangers placed upstream and downstream, respectively, of the reactor. The solution to be treated, laden with mineral matter to which an oxidizing gas has been added, is injected into the reactor for treatment after being preheated in the first heat exchanger. When the solution exits the reactor, the hot treated mixture is divided into two hot stream fragments. The first hot treated mixture stream fragment, the flow rate of which is kept constant by a diaphragm column, is used for controlling the temperature of the first heat exchanger and then discharged after being used in the first heat exchanger. The second hot treated mixture stream fragment is directly cooled and discharged when the second hot treated mixture stream fragment leaves the reactor.

  • Patent number: 8920733
    Abstract: The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations.

  • Publication number: 20140371496
    Abstract: The present invention provides an improved method for solvent liquefaction of biomass to produce liquid products such as transportation fuel. The method uses a novel solvent combination that promotes liquefaction relatively quickly, and it reduces the need to transport large amounts of hydrogen or hydrogen-carrying solvents. It operates at lower pressure than previous methods, does not require a catalyst or hydrogen gas or CO input, and provides very high conversion of biomass into a bio-oil that can be further processed in a petroleum refinery. It also beneficially provides a way to recycle a portion of the crude liquefaction product for use as part of the solvent combination for the biomass liquefaction reaction.

    Abstract: A gas generator includes a reactant capable of producing a gas and a gas outlet valve that can function as both a gas flow valve and a pressure relief vent, using the same gas flow path through the valve. When the valve is closed and the pressure within the gas generator is below a threshold pressure, a moveable valve member is biased against a valve seat to block the outlet port. When gas generator is coupled to the apparatus, an actuator is inserted into the valve, displacing the moveable valve member and separating it from the valve seat to open the valve. When the gas generator is uncoupled, pressure at or above a threshold displaces the moveable member, separating it from the valve seat to open the outlet port so pressure can be released to the external environment.

  • Patent number: 8303917
    Abstract: A hydrogen producing system and a hydrogen producing method by which hydrogen can be efficiently produced using abundant seawater as the raw material. A hydrogen producing method has a system (10) for producing hydrogen from seawater, and the hydrogen producing system (10) has an activation device (12) and a pipe line device (14). The activation device (12) has a closed space (S) for introducing the seawater (W) and a vapor ejection means (18) for ejecting high-temperature, high-pressure vapor (T) into the closed space (S), and the activation device (12) activates under high temperature and high pressure the seawater (W) in the closed space (S). The pipe line device (14) is a device for receiving and leading the high-temperature, high-pressure seawater activated by the activation device (12) and includes one or more seawater leading tubes (403-408) having any one of triangular, pentagonal, hexagonal and octagonal cross sections.

  • Patent number: 8192080
    Abstract: Improved treatment apparatus (120, 152) is provided for the treatment (e.g., molding, heating and/or curing) of objects such as parts or part precursors (148, 170) including wireless detection of a temperature parameter related to the objects during treatment thereof. The objects include associated microwire-type sensors (150, 174) which have characteristic re-magnetization responses under the influence of applied, alternating magnetic fields. The apparatus (120, 152) have treatment chambers (122, 153) sized to hold the objects to be treated, with one or more antennas (132, 124, 166) proximal to such objects and operable to generate interrogating alternating magnetic fields and to detect the responses of the sensors (150, 174). The detected temperature parameter information is used by an apparatus controller (146) to maintain desired ambient conditions within the treatment chamber (122, 153).

  • Publication number: 20120128538
    Abstract: Technologies are generally described for adjusting a pressure in a microreactor system. An example microreactor system may include a reaction chamber, wherein the reaction chamber is effective to receive at least one reactant, and carry out a reaction on the reactant to produce a product. An example method may comprise controlling a first electroosmotic pump to drive a first fluid toward the reaction chamber with a first force. In some examples. the method may further comprise controlling a second electroosmotic pump to drive a second fluid toward the reaction chamber with a second force. In some examples, the method may further comprise carrying out the reaction on the reactants in the reaction chamber to produce the product. The first and the second forces may be effective to generate a pressure inside the reaction chamber, where the pressure is greater than one atmosphere.

  • Patent number: 8153071
    Abstract: A fluid porting assembly for a microreactor comprising a process fluid passageway, a pliable seal, and a cooling fluid passageway is provided. The pliable seal is positioned in the vicinity of the process fluid outlet and is configured to define a sealing interface between the process fluid outlet and a fluid port of a microreactor. The cooling fluid passageway terminates at a cooling fluid interface and defines a dispensing gap between the cooling fluid interface and the sealing interface. The cooling fluid outlet is configured to distribute cooling fluid about a periphery of the pliable seal and to direct cooling fluid away from the periphery of the pliable seal through the dispensing gap when the pliable seal of the fluid porting assembly engages a fluid port of a microreactor. The cooling fluid removes heat from areas of the microreactor in the vicinity of the fluid port and pliable seal.
