  • Patent number: 7943195
    Abstract: A porous organosilica glass (OSG) film consists of a single phase of a material represented by the formula SivOwCxHyFz, where v+w+x+y+z=100%, v is from 10 to 35 atomic %, w is from 10 to 65 atomic %, x is from 5 to 30 atomic %, y is from 10 to 50 atomic % and z is from 0 to 15 atomic %, wherein the film has pores and a dielectric constant less than 2.6. The film is provided by a chemical vapor deposition method in which a preliminary film is deposited from organosilane and/or organosiloxane precursors and pore-forming agents (porogens), which can be independent of, or bonded to, the precursors. The porogens are subsequently removed to provide the porous film. Compositions, such as kits, for forming the films include porogens and precursors. Porogenated precursors are also useful for providing the film.

  • Publication number: 20110100209
    Abstract: During the conventional temperature swing adsorption (TSA) process, NF3 co-adsorbed with the impurities is vented during regeneration. This invention is a novel TSA cycle in which the co-adsorbed NF3 is recovered. In this novel TSA cycle, a control scheme is used to stop the adsorption prior to the saturation of the adsorber with impurities and use a recovery purge gas (either co-current or counter-current) to release the co-adsorbed NF3 off the saturated adsorber. The effluent of the inert purge gas can be combined with the effluent of the on-stream vessel or can be recycled to the feed of the on-stream vessel. 10%-100% of the co-adsorbed NF3 is recovered and made available as product in this novel TSA cycle. Thus the overall process yield of NF3 is increased. The removing of the co-adsorbed NF3 from the adsorber also prevents adsorber degradation thus prolonging the useful life of the adsorber.

  • Publication number: 20110083447
    Abstract: An apparatus and method for monitoring and/or controlling cryogenic cooling by measuring the opacity of the vapor cloud (113) generated from a cryogenic cooling device (112). The opacity is determined by measuring the reduction in intensity of a light beam (127) passed through the vapor cloud (113). The opacity measurements are used to control an operating parameter of the system, such as the cooling rate of the cryogenic cooling device (112). The opacity measurements may be normalized to compensate for variables, other than temperature of the workpiece (119) and cooling rate, which may affect the opacity of the vapor cloud (113).

  • Patent number: 7919057
    Abstract: A process and apparatus for producing a hydrogen-containing gas in a reformer where a furnace, which is independent of the reformer, heats the effluent from a prereformer prior to reacting the prereformer effluent in the reformer. The prereformer effluent may be heated in a heat exchange tube in the furnace where the heat exchange tube is positioned in the furnace to preclude direct radiation from any flames in the furnace thereby preventing local overheating of the heat exchange tube and preventing carbon formation in the heat exchange tube. Fuel and oxidant gas may be introduced into the furnace with significant excess oxidant gas, having a stoichiometric ratio of 1.8 to 2.8 for controlling the temperature of the heat exchange tube.
