摘要： Systems and methods are described for reducing the start-up time of flue gas conditioning processes. Such processes can include a gas removal unit configured to selectively remove a reactive gas from a flue gas stream using a catalyst and reagent to produce a scrubbed stream that is substantially depleted of the reactive gas. A heating device can advantageously be used upstream of the gas removal unit to thereby preheat the catalyst to an operational temperature and thereby reduce the start-up time of the process.

摘要： Plants and method of treating a combustion gas are presented in which NOx compounds are removed from the combustion gas to a predetermined level to thereby create a pre-cleaned combustion gas from which CO2 is removed in an absorber using an amine solvent. Preferably, the predetermined level of NOx compounds reduces nitro-amines, especially nitrosamine emission from the absorber to quantities of equal or less than 100 ppb.

摘要： A method of scrubbing mercury compounds and nitrogen oxides from a gas stream employing a scrubbing operation. The method involves the contact of the stream which contains mercury, SOx and NOx compounds with a sorbent to remove at least a portion of the latter compounds. This results in a partially cleaned stream. The method further involves contacting the latter stream with an oxidant to oxidize and remove substantially all residual nitrogen oxides, mercury and mercury compounds remaining in the stream.

摘要： A system for eliminating mist from a flue gas while providing air toxic control includes a wet scrubber housing having an inlet at one of the housing for the entry of the flue gas and an outlet at an opposite end of the housing for the exit of the flue gas. Sprayers are located in the housing for spraying the flue gas with a cleaning liquid in order to remove contaminants from the flue gas. At least one heat exchanger is located in the housing above the sprayers in order to remove entrained contaminants from the flue gas by cooling the flue gas. The flue gas is channeled from the inlet past the collection trays, sprayers and heat exchanger prior to exiting the housing through the outlet. A mist eliminator is also provided for eliminating mist from the flue gas.

摘要： An apparatus for improved removal of particulates and contaminants from a flue gas produced by the combustion of waste materials or fossil fuels in industrial processes having at least one horizontally oriented heat exchanger stage in which a wet scrubbing solution, such as an alkali reagent is sprayed in the same direction as the flue gas flow and a drain mechanism is located below the horizontally oriented heat exchanger. The horizontal orientation of the heat exchanger and the location of the drain mechanism increase the removal efficiency of very small particulates and contaminants. A collection tank is connected to the drain mechanism. A spray washing system is provided adjacent a mist eliminator and one or more additional heat exchanger stages for unplugging the heat exchanger and enhancing small particulate removal within the system.

摘要： A system for removing SO.sub.2, NO.sub.2, and other contaminants from flue gases uses hydrogen peroxide (H.sub.2 O.sub.2) as the reagent to convert the oxides of sulfur and some of the oxides of nitrogen (NO, NO.sub.2, etc.) to more stable oxidation states. Acids formed as a result of this conversion, namely sulfuric acid (H.sub.2 SO.sub.4) and nitric acid (HNO.sub.3) can then be neutralized with limestone or, alternatively, the sulfuric and nitric acids can be collected and processed for sale as an industrial product.

摘要： A dual-fluid low pressure drop atomizer utilizes extended wear life material and comprises a nozzle head having a secondary mix chamber therein for receiving a mixture of a first compressible fluid and a second fluid containing solids from a primary mix chamber. The nozzle head also has an orifice therein communicating with and adjacent to the secondary mix chamber for discharging a jet of the mixture. The orifice and the secondary mix chamber form an approximate right angle therebetween. An inner barrel is connected to the nozzle head at the primary mix chamber and supplies the first fluid to the nozzle head. An outer barrel is arranged around the inner barrel creating an annulus therebetween and is also connected to the nozzle head for supplying the second fluid to the nozzle head. Wear resistant material provided in the primary and secondary mix chambers reduces erosion within the atomizer head.
