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.
Claims16
A method for removing VOC, concentrations in ambient air comprising VOC, the method comprising, exposing the ambient air in a suitable reaction chamber 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 VOC in the ambient air, wherein the ambient air after reaction in the reaction chamber is transported through a scrubber, and wherein the scrubber is a packed bed having an aqueous phase flowing downward through the packed bed and an air stream flowing up or sideways, to provide the ambient air with a removed concentration of VOC.
