Abstract
A method for removing methane and non-methane volatile organic compound concentrations from a gas stream. The method includes exposing the target gas to a halogen gas and a light from a suitable light source having a wavelength sufficient to activate halogen gas to halogen radicals, wherein the halogen radicals react with the VOC in the target gas to provide the target gas with a removed concentration of VOC as well as a device including a reaction chamber for reacting the halogen radicals with the VOC in the target gas.
Claims10
A device for removing methane concentrations in a target gas comprising methane, wherein the device comprises a) a reaction chamber for exposing the target gas to a halogen gas and a light from a suitable light source having a wavelength sufficient to activate halogen gas to halogen radicals;
- b) an inlet for receiving the target gas;
- c1) an inlet for providing halogen gas into the reaction chamber, the inlet being separate from the inlet for receiving the target gas;
- c2) an outlet for providing the target gas with a removed concentration of methane;
- d) a light source for providing a wavelength sufficient to activate halogen gas to halogen radicals;
- e) a wet scrubber for decreasing or removing halogen acid, unreacted halogen, formaldehyde, CO, CO2 before the target gas with the removed methane concentrations leaves through the outlet, and f) a removal unit for removing ammonia from the target gas before being exposed to the halogen gas.
