Abstract
The pollution of the atmosphere by sulfur dioxide is one of the gravest of all in public nuisance problems, especially in the industrial regions. A practically applicable method in industry for the removal of sulfur dioxide has been studied. The Kiyoura-T .I .T. process utilizes the oxidation method to convert S02 of the flue gas to S03 in the presence of vanadium oxide. A limited amount of water vapor present in the flue gas reacts with S03 to form H2SO4. Ammonia is then introduced to the gaseous mixture, which is now at the suitable temperature, to form ammonium sulfate. Conditions are controlled to produce ammonium sulfate of the right size to produce aggregate that may be removed by a dry cyclone separator.Keywords
