Abstract
Sulfur dioxide and nitrogen oxides can be removed from effluent gases with increased efficiency by blowing contaminated air present in the irradiation room into a stream of the effluent gases before the mixture is delivered to a reaction chamber to be irradiated with an ionizing radiation or ultraviolet light. This provides also a convenient process for purifying the contaminated air containing nitrogen oxides and ozone before release into the atmosphere. Thus, simultaneous purification of industrial effluent gases and contaminated air is advantageously carried out.
