    摘要: This invention is a device and a process for controlling the emission of volatile organic components. The invention is useful on gaseous or vapor-containing streams containing a minor amount of organic material, particularly on fairly dilute streams or those containing only a few parts per million of the organic material. The device is useful in adsorbing organics as might be found emanating from paint spray booths, restaurants, print shops, dry cleaners, furniture manufacturers, and bakeries.The device may be two-stage including an adsorber and a catalytic oxidation reactor or may be of such a configuration that the same bed is used both as the adsorber and catalytic oxidation reactor. In the former configuration, a first stage contains an electrically conductive adsorbent bed, potentially comprising an adsorbent placed on a conductive support of fibers, foil, or other structure. The adsorbent removes the organic from the gaseous stream as that stream passes through. When the adsorbent is loaded with volatile organic, a voltage is applied to the conductive support and the adsorbed organic material is desorbed. The stream containing the desorbed organic is passed through a catalyst bed where a catalyst (which may also be on a conductive support) oxidizes the volatile organic to a harmless material which may (perhaps after other treatment) be emitted to the atmosphere.

    摘要: This invention is a comparatively high pressure combustion process having a two stages in which a fuel is stepwise combusted using specific catalysts and catalytic structures and, optionally, having a final homogeneous combustion zone. The choice of catalysts and the use of specific structures, including those employing integral heat exchange, results in an overall catalyst structure which is stable due to its comparatively low temperature. The product combustion gas is at a temperature suitable for use in a gas turbine, furnace, boiler, or the like, but has low NO.sub.x content.

    摘要: A support structure for securing a catalyst structure comprising a multiplicity of longitudinally disposed channels for passage of a flowing gas mixture within a reactor, said support structure being comprised of a monolithic open celled or honeycomb-like structure formed by thin strips or ribs of high temperature resistant metal or ceramic which abuts against one end of the catalyst structure, and extends in a direction perpendicular to the longitudinal axis of the catalyst structure to essentially cover an end face (at either the inlet end or outlet end or both) of the catalyst structure with the support structure being secured on its periphery to the reactor wall. The strips or ribs making up the support structure are bonded together to form a unitary structure having cellular openings at least as large as the catalyst structure channel openings. The cellular openings in the support structure are also positioned to be in fluid communication with the channels of the catalyst structure thus affording essentially unaltered gas flow from the catalyst structure through the support structure.

    摘要: A flow body flow meter includes a flow body and a sensor having one or more probes in the flow body. As a wet gas stream enters the flow body, an internal passage imparts angular momentum to the stream to induce a rotating flow. The wet gas stream at least intermittently carries liquid phase particles and the inertia of the denser liquid phase particles separates them from the rotating flow. The probes of the sensor are located in a part of the rotating flow that is free of any liquid phase particles. The internal passage may include an axial swirler and a cylindrical section downstream from the axial swirler. The axial swirler imparts the nonlinear motion to the stream, and tips of the probes are located near a center axis of the cylindrical section so they are free of any liquid phase particles.

    摘要: This invention is a graded catalyst comprising palladium and also a partial combustion process in which the fuel is partially combusted using that catalyst. The catalyst utilizes a catalytic support structure suitable for high flow rates of combustible gas mixtures through it. The catalyst is situated on the support so that in the flowing gas stream a leading portion of the support has a higher combustion activity, such as by a higher concentration of catalytic metal, than has the trailing portion. The combination of graded catalyst and support provides a low "light off" temperature for the combustible gas (only a low preheat temperature is needed to cause the combustion reaction to begin) and yet does not cause "hot spots" to occur because of excess activity. The combustion gas produced by the catalytic process may be at a temperature below the adiabatic combustive temperature, may be used at that temperature, or fed to other combustion stages for further use in a gas turbine, furnace, boiler, or the like.

    摘要: This invention relates to an electrically-heated catalyst (EHC) and a start-up method of a gas turbine engine for combusting a hydrocarbonaceous fuel/oxygen-containing gas mixture using this electrically-heated catalyst. The catalytic structure is electrically heated to a predetermined temperature prior to start up of the turbine so as to reduce emissions during the start-up of the system. The EHC unit is a stacked or spirally wound layering of flat and corrugated thin metal foils which forms a plurality of axially-extending, longitudinal channels. The channels are preferably coated on one surface with a catalytic material, leaving the other surface free from the reaction to act as a heat sink, making the design an IHE (integral heat exchange) catalytic unit. The preferred embodiment of the EHC has electrodes outside of the fuel/oxygen-containing mixture stream, and uses electrical power having a predetermined voltage in the range of 100 to 200 volts to heat the unit. A method for using the EHC in the start-up of a gas turbine is also disclosed wherein an electrical power is applied to heat the EHC a predetermined temperature prior to the fuel/oxygen-containing mixture being introduced and may be left on for a certain period of time after the introduction of the fuel/oxygen-containing mixture. The EHC may be maintained at the desired predetermined temperature by modulating the applied voltage. The electrical power is terminated when any one of several conditions are met including when the heat of the catalytic reaction is sufficient to maintain the catalyst at its steady-state condition or when a certain period of time has elapsed.
