ABSTRACT:
Combustion products, especially those from electric power generating installations burning high sulfur fuels are treated to remove solids and then to separate physically sulfur containing constituents, such as SO.sub.2 and/or SO.sub.3 from other gases in the combustion products mixture by means of an ultra high speed gas centrifuge or a gas cyclone. The recovered oxides of sulfur in a heated condition are utilized in any desired chemical reaction. For example, they may be passed over dry NaCl and reacted therewith to yield sodium sulfate and chlorine, both of which can be recovered, and/or they may be passed directly over suitable catalysts in the presence of air to produce a pure grade of sulfur trioxide which can be absorbed in water to manufacture concentrated sulfuric acid.
