摘要： The present invention relates to a process for removing nitrogen oxides from gas streams such as furnace or utility boiler flue gas streams. An ozone adsorption system is used to adsorb and concentrate ozone. A slip stream containing nitrogen oxides is introduced into an ozone adsorption system to desorb ozone and the ozone-containing slip stream gas is then directed to a reactor duct along with the primary nitrogen oxide-containing gas stream where the nitrogen oxides are converted to N.sub.2 O.sub.5.

摘要： The present invention relates to a process for removing nitrogen oxides from gas streams such as furnace or utility boiler flue gas streams. An adsorber system is used to adsorb nitrogen oxides from the flue gas streams. An oxygen/ozone gas stream contacts the nitrogen oxides to convert the nitrogen oxides to N2O5 which will exit the adsorber with the oxygen stream.

摘要： Nitric oxide is removed from a gas stream by contacting the gas stream with oxygen in the presence of a metal-cation exchanged zeolite, thereby oxidizing the nitric oxide to nitrogen dioxide, then contacting the resulting nitrogen dioxide-containing gas stream with ozone, thereby converting the nitrogen dioxide to nitric acid, nitric acid precursors or mixtures thereof, then contacting the gas stream with an aqueous liquid, thereby scrubbing the nitric acid, nitric acid precursors or mixtures thereof from the gas stream. Contact of the gas stream with oxygen in the presence of a zeolite is carried out at a temperature above the temperature at which significant adsorption of nitrogen dioxide occurs, and the aqueous liquid used as scrubbing agent preferably has a pH greater than 7.

摘要： A process for the removal of a high percentage of NOx and SOx from the gaseous effluent of a metal pickling operation comprising passing the effluent through an aqueous scrubber, treating the gaseous effluent from the scrubber with ozone, passing the effluent from the ozone treatment through a second aqueous scrubber thereby removing at least 80 vol % of the NOx and SOx present in the original effluent. The scrubbing solutions in both of the scrubbers preferably have a pH of from 7 to 14, more preferably 10 to 14. The scrubbing solutions in both scrubbers are caustic solutions containing sodium hydroxide or calcium hydroxide. The NOx and SOx in the scrubbers are converted into nitrate salts and sulfate salts, which are removed from the scrubbers.

摘要： The present invention relates to a process for removing nitrogen oxides, sulfur oxides, mercury and mercuric oxide from gas streams such as furnace or utility boiler flue gas streams, particularly those derived from coal-fired utility boilers, or from a gas stream from another pollutant abatement process. Ozone will react with the impurities in the gas stream to form mercuric oxide and higher oxides of nitrogen which can be removed by scrubber means. Additionally, and alternatively, the present invention provides for the use of ozone and ultraviolet radiation to remove nitrogen oxides, sulfur oxides and mercury from gas streams.

摘要： Nitrogen oxides are removed from a waste gas stream by contacting the waste gas stream with ammonia, thereby reducing the nitrogen oxides to nitrogen. Residual nitrogen oxides and unreacted ammonia in the waste gas stream leaving the nitrogen oxides reducing step are oxidized to nitrogen pentoxide or nitric acid by contacting this gas stream with ozone. Contact of the ozone and waste gas is preferably carried out in the presence of an aqueous solution at a pH above about 9 and at a temperature above about 75° C., and this step is preferably carried out in the presence of an ammonia-oxidizing catalyst.

摘要： A method for blending deuterium-containing gas mixtures used for optical fiber manufacturing and finishing and recovering, purifying and recirculating these mixtures. A process is disclosed for producing optical fiber wherein the optical fiber is treated by soaking the optical fiber with a deuterium-containing gas mixture. The spent or unused deuterium-containing gas is recovered from the chamber containing the optical fiber that has been soaked and purified. This purified deuterium-containing gas is then mixed with fresh deuterium gas and analyzed for purity. If the purity is of sufficient quality, the blend of deuterium gases is directed to a storage tank and onwards to the process chamber containing the optical fiber which will be soaked. Additionally, the purified blend of deuterium-containing gas and fresh deuterium gas can be added directly to the process chamber.

摘要： Gas mixtures having precise compositions are prepared by separately pumping the components in liquid phase through piping, vaporizing the components, blending the components and analyzing the mixture for composition. A signal sent to a control unit causes any necessary change in the rate of pumping of the liquid components to reduce the difference between the measured concentration and the desired concentration. When the composition is within desired limits it is charged into gas cylinders.

摘要： A method of depositing a solid substance on the surface of the substrate in which the solid substance is dissolved in a solvent to create a first solution. The solid substance is less freely divided prior to dissolution than when deposited on the substrate and the deposition density of the solid substance on the substrate is regulated at least in part by solid substance concentration. The solid substance is insoluble in a liquified gas and the first solution is soluble in the liquified gas. The solvent also is capable of depressing the freezing point of the liquified gas upon expansion of the liquified gas. The first solution is dissolved in the liquified gas to create a second solution having a sufficient concentration of the solvent relative to the liquified gas that solidification of the liquified gas is substantially prevented upon the expansion thereof. Preferably, this concentration of solvent is a minimum to prevent overuse of environmentally hazardous solvents. The solution is sprayed against the substrate so that a portion of the liquified gas flashes into a vapor and the second solution containing a remaining portion of the liquified gas contacts and thereby coats the surface substrate. The remaining portion of the liquified gas is evaporated along with the solvent, so that the solid substance remains as a deposit on the substrate. The method has particular application to making very free depositions such as are required in the electronics industry to coat contacts of printed circuit boards with flux prior to soldering.
