Abstract
The present invention solves the existing problem of using very expensive oxidation reagents, such as HOand ozone, in removal of NOand SOfrom flue gases, by performing simultaneous oxidation of NOand SOwith atmospheric oxygen in a combined system for catalytic oxidation and wet-scrubbing of both NOand SOfrom a flue gas and manufacturing fertilisers. Two major configurations of the oxidation system are disclosed in the present invention. The first configuration operates on oxygen-enriched air to increase efficiency of the oxidation reaction and requires an additional oxygen concentrator unit. The second configuration operates on atmospheric air at ambient conditions and requires an additional catalyst activation unit. In the second configuration, the efficient oxidation process is carried out at low temperatures of about 30-90° C. in the presence of recovered and re-activated catalyst. This temperature is a result of the exothermic character of the reaction, and therefore, no heating is required in the process.
