An apparatus for treating pollutants in a gas may include a source of hydrogen peroxide, and a treatment injector for creating and injecting dissociated hydrogen peroxide into the flow of gas. The treatment injector may further include an injector housing having an inlet, an outlet, and a hollow interior extending therebetween. The inlet may be connected in fluid communication with the source of hydrogen peroxide so that hydrogen peroxide flows through the hollow interior and toward the outlet. At least one ultraviolet (UV) lamp may be positioned within the hollow interior of the injector housing. The at least one UV lamp may dissociate the hydrogen peroxide flowing through the tube. The dissociated hydrogen peroxide may be injected into the flow of gas from the outlet for treating pollutants, such as nitrogen oxides.

Apparatus and method for treating pollutants in a gas using hydrogen peroxide and UV light

A method for removing NO from gas streams emanating from stationary combustion sources and manufacturing plants utilizes the injection of hydrogen peroxide into the gas stream for rapid gas-phase oxidation of NO to NO and water-soluble nitrogen acids HNO and HNO . The nitrogen acids may be removed from the oxidized gas stream by wet scrubbing or by contact with a particulate alkaline material to form a nitrite/nitrate salt.

Method for removal of nitrogen oxides from stationary combustion sources

Gas flux rate from a surface is measured using an elongated tubular housing having a lower open end and an upper open end with a support positioned within the housing a predetermined distance from the lower open end. A gas sampling wand extends into the housing from the upper open end and is supported on the support. The wand has a lower open end at the support generally co-planar with the lower open end of the housing. An air baffle is coupled to the upper open end of the housing for reducing velocity and pressure fluctuations of atmospheric air entering the housing from the upper end. A detector is coupled to the wand for measuring the concentration of selected gases within the housing. A funnel-shaped hood circumscribes the lower open end of the wand and increases the sample collection area of the wand. An air pump is coupled to the wand for drawing air and gases into the wand from the area adjacent the lower open end of the housing. A gas impervious conduit couples the wand to the detector and a flow control valve is coupled to the conduit for controlling the gas flow rate to the detector. A flow meter is coupled in a gas flow path for providing data representative of the volume of gas flowing to the detector. The gas emission rate from the surface is computed using the gas flow rate data and gas concentration data divided by the area encompassed by the housing.
