LoTOx Process

British Oxygen Corporation's low-temperature oxidation process, LoTOx, was originally developed for NOZ control but has shown multipollutant reduction capabilities, as well [98]. The LoTOx process injects ozone into the flue gas at temperatures below 300° F to react with NO and NO2 to form soluble higher oxides that can be removed with a wet scrubber. NOZ reduction efficiencies greater than 90% have been achieved and, because the ozone also oxidizes elemental mercury to soluble oxide species, mercury removal is also possible, with reductions greater than 90% achieved in laboratory tests. Capital costs for LoTOx are estimated at $289/kW [98]. Levelized operating and maintenance costs are estimated at $12.96 mills/kWh.
