Drawing on our unparalleled experience in industrial ozone applications, we have developed a series of process technologies to remove nitrogen oxides (mainly NO and NO2) – known as NOx – and other contaminants such as VOCs from process or exhaust gas streams.
In the past, NOx emission control generally relied on costly technologies that operated at high temperatures – often with adverse side-effects for other process equipment. Many operators are thus looking for a more effective way to remove NOx from exhaust streams.
Low-temperature oxidation is an extremely effective way of managing harmful emissions. Our innovative process employs ozone to oxidize NOx to higher oxides of nitrogen (such as N2O5). As N2O5 is a highly soluble species of NOx, it can be effectively removed with conventional air pollution control (APC) equipment, such as wet or semi-dry scrubbers or wet electrostatic precipitators (WESP). Other contaminants such as mercury can also be oxidized using this technology.
This flexible end-of-pipe technology can be configured for efficiency levels between 30 and 95% and can be integrated in the wet/dry scrubbing systems used in most air pollution control equipment.
Ozone is generated from oxygen on site and on demand and is either completely consumed in the process or residual ozone is destroyed in the scrubber system.
