摘要： A heating system for compressed parts capable of controlling process atmosphere and pressure includes an accommodating body, a heating device, an atmosphere controlling device, and a processing pressure adjusting device. The heating device is disposed inside or outside of the accommodating body to heat a component to be heated, so as to remove an impurity within the component to be heated. The atmosphere controlling device transports a reaction gas, such as hydrogen, oxygen, water vapor, or plasma, into a cavity for reacting with the impurity within the component to be heated. A phase transition or a chemical reaction can be carried out, such that the impurity is gasified, oxidized, carbonized, or disintegrated. The processing pressure adjusting device uses an inert gas (e.g., a nitrogen gas or an argon gas) to control the processing pressure in the cavity to be from 800 Torr to 10−2 Torr.

摘要： Disclosed are devices and methods for capturing carbon dioxide and other gases. All gas-capturing systems employ chemical fluid/media for binding purposes. One system delivers chemicals in droplet form, while another system delivers feed gas in bubble form. All systems employ an admixing chamber for confining and uniting particles of matter, as well as streaming means for placing gas in confinement. The droplet-based delivery system packetizes chemicals using an atomizing device, while the bubble-based delivery system packetizes gaseous feedstock using metering means, rerouting means, perturbation means, and stream-dividing means. The droplet and bubble systems feature common or unique advantages relating to chemical flow, surface area, and/or progressive cycling. These advantages increase the efficiency of gas-capturing devices in general and decarbonizing devices in particular.

摘要： A plasma abatement process for abating effluent containing compounds from a processing chamber is described. A plasma abatement process takes gaseous foreline effluent from a processing chamber, such as a deposition chamber, and reacts the effluent within a plasma chamber placed in the foreline path. The plasma dissociates the compounds within the effluent, converting the effluent into more benign compounds. Abating reagents may assist in the abating of the compounds. The abatement process may be a volatizing or a condensing abatement process. Representative volatilizing abating reagents include, for example, CH4, H2O, H2, NF3, SF6, F2, HCl, HF, Cl2, and HBr. Representative condensing abating reagents include, for example, H2, H2O, O2, N2, O3, CO, CO2, NH3, N2O, CH4, and combinations thereof.

摘要： A method and system for ozone treatment of air for a vehicle cab where the system monitors the level of ozone in treated air, and is arranged to perform further treatment of the treated air if the detected ozone levels exceed a threshold level. Such further treatment may include adjusting the flow rate of air in the system, recirculating the treated air through an air filter to remove ozone from the treated air; providing an ozone-reducing substance to the treated air to lower the level of ozone in the treated air, and/or ejecting at least a portion of the treated air to the environment.

摘要： An inlet assembly for a an abatement burner includes: an inlet conduit operable to convey an effluent gas stream to be treated from an inlet aperture via a bore to an outlet aperture for treatment; and a lance conduit operable to convey a fuel gas from a gas inlet aperture via a gas bore to a gas outlet aperture positioned within the bore for mixing with the effluent gas stream, a cross-sectional area of the gas bore increasing towards the gas outlet aperture. In this way, the expansion caused by the increasing cross-sectional area of the gas bore enhances the mixing of the fuel gas with the effluent gas stream which provides for improved destruction and removal efficiencies (DRE), which enables the inlet assembly to be operated with reduced quantities of fuel gas, while still maintaining required levels of DRE.

摘要： A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.
