Nitric oxide in a gaseous stream is converted to nitrogen dioxide using oxidizing species generated at least in part using in situ UV radiation sources. The sources of the oxidizing species include oxygen and/or hydrogen peroxide. The oxygen may be a component of the gaseous stream or added to the gaseous stream, preferably near a UV radiation source, and is converted to ozone by the UV irradiatio...

A system and method for the removal of metals such as mercury from a gas stream. The method involves contacting a gas stream containing the target metals with reactive chemical species generated in a plasma device. The metal to be removed is chemically converted into forms enabling capture in either conventional particulate removal devices or in a wet scrubber for the capture of a soluble chemical...
