    摘要： In a method for removing a portion of contaminants, such as nitrogen oxides, from an exhaust gas stream of a combustion process, the exhaust gas stream is conveyed through a gas distributor at an inlet of a wet horizontal spray scrubber. A distributor separates the gas stream into a plurality of spaced apart partitioned gas streams. The gas stream is partitioned in the chamber of the scrubber without the need for any physical partitions or obstructions positioned in the chamber. A preselected number of the partitioned gas streams are mixed with ozone to oxidize the contaminants in the gas streams. The oxidized gas streams are then sprayed with an aqueous medium to capture the oxidized contaminants and remove them from the treated gas streams. The treated gas streams are then recombined with the untreated gas streams. Excess ozone present in the treated gas streams is consumed by oxidation of contaminants in the untreated gas streams before the combined gas stream is released to the atmosphere. The partitioned gas streams selected for mixing with ozone directly correlates to the amount of nitrogen oxides that are desired to be removed from the exhaust gas stream.

    摘要翻译： 在从燃烧过程的废气流中除去一部分污染物（例如氮氧化物）的方法中，废气流通过湿式卧式喷雾洗涤器的入口处的气体分配器输送。 分配器将气流分离成多个间隔分隔的气流。 气流在洗涤器的腔室中分隔，而不需要位于腔室中的任何物理分隔物或障碍物。 将预选数量的分配的气流与臭氧混合以氧化气流中的污染物。 然后用水性介质喷射氧化气体流以捕获氧化的污染物并将其从经处理的气流中除去。 然后将经处理的气流与未处理的气流重新组合。 处理后的气流中存在的过量的臭氧在组合气体流被释放到大气中之前通过未处理气体流中的污染物的氧化被消耗。 选择用于与臭氧混合的分隔气流直接与期望从废气流中除去的氮氧化物的量相关。

    摘要： A method to reduce the emission of contaminants such as nitrogen oxides from the operation of a submerged combustion vaporizer. Fuels are combusted and the combustion gases are fed to an aqueous system which heats up and vaporizes cryogenic fluids in tube bundles in the submerged combustion vaporizer. Ozone is added to the aqueous system and will react with the contaminants allowing for their removal from the aqueous system.

    摘要： A method for reducing NOx and recovering waste heat from a stream of exhaust gas from a fossil fuel fired turbine includes contacting the stream of exhaust gas between an economizer and an evaporator with ozone gas to convert the NO to nitrogen dioxide (NO2) thereby forming a stream of exhaust gas comprising NO2 and residual NO. The method further includes, contacting the stream of exhaust gas comprising NO2 and residual NO with water mist to create an exhaust stream comprising nitric acid (HNO3) and residual NO. The method further includes cooling the stream of exhaust gas comprising HNO3 and residual NO, collecting a first residual water film on a first condensing medium to capture the HNO3 and removing the first water film and HNO3.
