Title of Invention | AN IMPROVED PROCESS FCR THE MANUFACTRE OF SULFURIC ACID |
---|---|
Abstract | An improved process for the m manufacture of sulfuric acid, comprising combustion of a source of sulfur with an oxygen-containing gas in a burner to produce a combustion gas stream comprising sulfur dioxide and oxygen. The improvement comprises introducing water vapor into the gas stream at a point between said burner and the said absorption zone, at least a portion of the water vapor reacting with sulfur trioxide in the gas phase; and recovering heat energy from the vapor phase heat in an indirect 1 heat exchanger from said gas stream to stream having a pressure at least about 8 bar higher than the pressure of said water vapor as introduced into the gas stream , or to feed water from which said indirect heat exchanger is located upstream of said absorption zone. |
