  • Patent number: 11675376
    Abstract: A temperature-controlled pressure regulator assembly includes a regulator having a regulator body, a valve seat, an inlet, an outlet, and defines a flow passage connecting the inlet and the outlet. A control element controls the device, a portion of the flow passage extends through a heat chamber, and a heater is positioned to heat the chamber thereby conveying heat to a fluid in the flow passage. A controller is electrically coupled to the heater and is coupled to a power source. A thermal cut-off fuse is coupled to a control circuit, with the thermal cut-off fuse arranged to electrically decouple the heater from the control circuit in response to a temperature exceeding a threshold, thereby deactivating the heater. The thermal cut-off fuse is disposed in a circular fuse holder and positioned adjacent the heater and adjacent a longitudinal center of the heat chamber.

  • Patent number: 11339056
    Abstract: Disclosed are methods and compact apparatus for controlled, on-demand ammonia generation from urea. The process gasifies an aqueous urea solution in a chamber utilizing hot gas while controlling the flows of aqueous urea solution and hot gas to achieve complete gasification of the aqueous urea solution and form a gas mixture comprising ammonia, isocyanic acid, carbon dioxide and water vapor, which is passed through a catalyst bed containing particulate transition metal oxide to convert substantially all of the isocyanic acid to ammonia. A catalyst support and the catalyst bed are aligned with the gasification chamber at the lower end of said chamber to provide a degree of back pressure on the gases in the gasification chamber to isolate the gasification chamber from turbulent exit effects caused by equipment downstream of the thermal reactor. A sample of the product stream is treated to remove water and ammonia, and analyze for carbon dioxide content to control the process.

  • Patent number: 8936734
    Abstract: A system and method for splitting water to produce hydrogen and oxygen employing focused polarized sunlight energy is disclosed. Hydrogen and oxygen may then be stored for later use as fuels. The system and method use inorganic capping agents that cap the surface of semiconductor nanocrystals to form photocatalytic capped colloidal nanocrystals, which may be deposited and oriented on a substrate to form an oriented photoactive material. The oriented photoactive material may be employed in the system to harvest sunlight and produce energy necessary for water splitting. The system may also include a light polarization system and elements necessary to collect, transfer, and store hydrogen and oxygen, for subsequent transformation into electrical energy.

  • Publication number: 20150014590
    Abstract: Systems and methods for pre-treatment of acid gas are presented in which ammonium is removed from the acid gas in an absorber that is operated at significantly elevated temperature using dilute phosphoric acid. While seemingly incompatible, absorbing ammonia at high heat in the absorber will allow for production of a diammonium phosphate product that is ultra-low in residual sulfurous compounds and prevent crystallization of phosphate salts due to the increased solubility of the salts in the hot diluted solvent.

  • Patent number: 8932406
    Abstract: The molecular etcher carbonyl fluoride (COF2) or any of its variants, are provided for, according to the present invention, to increase the efficiency of etching and/or cleaning and/or removal of materials such as the unwanted film and/or deposits on the chamber walls and other components in a process chamber or substrate (collectively referred to herein as “materials”). The methods of the present invention involve igniting and sustaining a plasma, whether it is a remote or in-situ plasma, by stepwise addition of additives, such as but not limited to, a saturated, unsaturated or partially unsaturated perfluorocarbon compound (PFC) having the general formula (CyFz) and/or an oxide of carbon (COx) to a nitrogen trifluoride (NF3) plasma into a chemical deposition chamber (CVD) chamber, thereby generating COF2. The NF3 may be excited in a plasma inside the CVD chamber or in a remote plasma region upstream from the CVD chamber.

  • Patent number: 8926931
    Abstract: The present invention generally relates to a catalytic gasification of coal. Catalytic gasification of a Wyodak low-sulfur sub-bituminous coal from the Powder River Basin of Wyoming was investigated using an inexpensive sodium carbonate catalyst applied via incipient wetness impregnation. Experiments in an atmospheric pressure fixed-bed laboratory gasifier were performed to evaluate the effects of reaction temperature, feed gas steam content, and Na2CO3 loading on the catalytic gasification of the Wyodak coal. The temperature range investigated (700-900° C.) was selected with consideration of the Na2CO3 melting point (850° C.) to reduce the loss by volatilization of sodium. Sodium was found to be active during both pyrolysis and gasification steps. The catalyst was most cost-effective at addition levels of approximately 3 wt %. The random pore model provided a good fit to the conversion versus time data collected under both the catalytic and the uncatalytic conditions.

  • Patent number: 8920714
    Abstract: A corrosion prevention and control composition and method comprises combining primarily two-component polyurethane foam formed by reacting polyols with an isocyanate compound, and a 2 to 10 percent by weight of either an organic or inorganic gas-phase corrosion inhibitor. The closed cell foam provides a barrier protection for the underlying corrodible surface, while the inhibitor protects the metal from the absorbed moisture vapor, thereby preventing corrosion from occurring at the foam/metal interface. The resulting foam and inhibitor composition maintains better adhesion to the underlying corrodible structure in corrosive environments.

  • Publication number: 20140374659
    Abstract: Disclosed is a process for the concurrent production of hydrogen and sulphur from a H2S-containing gas stream, with zero emissions. The method comprises the thermal oxidative cracking of H2S so as to form H2 and S2. Preferably, the oxidation is conducted using oxygen-enriched air, preferably pure oxygen. The ratio H2S/O2 in the feedstock is higher than 2:1, preferably in the range of 3:1-5:1.

  • Publication number: 20140366724
    Abstract: The invention is a process involving membrane-based gas separation for separating and recovering carbon dioxide emissions from combustion processes in partially concentrated form, and then transporting the carbon dioxide and using or storing it in a confined manner without concentrating it to high purity. The process of the invention involves building up the concentration of carbon dioxide in a gas flow loop between the combustion step and a membrane separation step. A portion of the carbon dioxide-enriched gas can then be withdrawn from this loop and transported, without the need to liquefy the gas or otherwise create a high-purity stream, to a destination where it is used or confined, preferably in an environmentally benign manner.

  • Patent number: 8900334
    Abstract: The goal of the invention consists in making available a method for supplying fuel to a pressurized gasification system, which ensures, in economically efficient manner, that the emission of pollutants from the coal transfer and the transport is minimized or completely avoided. This is achieved in that a gas that contains at least 10 ppm vol. CO is used for transfer and/or conveying, whereby a gas that contains oxygen is mixed into this gas, and that this gas mixture is heated to a temperature that oxidizes at least 10% of the pollutants contained in the gas.

  • Publication number: 20140275297
    Abstract: Processes, systems and equipment can be used to convert carbonaceous fuel to an output gas stream that includes CO as a primary C-containing product. In some embodiments, the processes and systems also can produce H2 in a separate reaction, with the H2 advantageously being capable of being combined with the CO from a partial oxidation process to provide syngas which, in turn, can be used to produce fuels and chemicals. The processes and systems can be tuned so as to not produce significant amounts of CO2 and do not require an air separation unit.
