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.
Claims19
A method for removing methane concentrations in a target gas comprising methane, the method comprising, optionally in a suitable reaction chamber, exposing the target gas to a halogen radical precursor and a light from a suitable light source having a wavelength sufficient to activate the halogen radical precursor to halogen radicals, wherein the halogen radicals react with the methane in the target gas to provide the target gas with a removed concentration of methane.
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;
- c) 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;
- and e) optionally a filter and/or scrubber for decreasing or removing halogen acid, unreacted halogen, formaldehyde, CO, CO 2 before the target gas with the removed methane concentrations leaves through the outlet.
