ABSTRACT:
The present invention relates to a system and process for controlling air pollution and basically relates to a photochemical method of removing contaminant compounds, such as sulfur dioxide and nitrogen oxides, from polluted effluent gas systems. Such contaminant compounds are first formed into complexes (such as an electron donor-acceptor molecular complexes) and clusters. After the contaminant compounds become associated with these complexes and clusters, ultraviolet light is introduced into the system resulting in the complexes or clusters being photooxidized. The photooxidization of the complexes or clusters generally tends to internally rearrange the complexes or clusters and to form non-volatile acid products that readily condense on available nuclei. The acid-like products resulting from the photooxidization treatment of the complexes or clusters can be removed from the gas system by conventonal particulate removal techniques.
