Abstract:
A process for producing sulfuric acid from a gas stream containing water, sulfur oxides and oxygen comprising the following sequential steps:a.) subjecting said gas stream to a means for rapidly increasing the temperature thereof and thereby heating the gas stream from about 300.degree. F. to about 600.degree. F. at a rate sufficient to convert the sulfur dioxide in said gas into sulfur trioxide in one step without the presence of a catalyst and sulfuric acid vapor is formed;b.) passing the gas containing sulfuric acid vapor through a condensation chamber maintained at above the boiling point of water but below the condensation temperature of sulfuric acid so as to condense out the sulfuric acid; andc.) passing the condensed sulfuric acid through a solids/sulfuric acid separation means to purify and collect the sulfuric acid.
