    摘要： A contact process for manufacture of sulfuric acid in which the vapor phase heat of formation of sulfuric acid in the sulfur trioxide conversion gas and the heat of absorption of SO3 in sulfuric acid is recovered by transfer of heat from the absorption acid to high pressure boiler feed water that is fed to a waste heat boiler where steam is generated at a pressure of at least 40 bar by transfer of heat from sulfur dioxide combustion gas.

    摘要： A contact process for manufacture of sulfuric acid is disclosed in which the vapor phase heat of formation of sulfuric acid in the sulfur trioxide conversion gas and the heat of absorption of SO3 in sulfuric acid is recovered by transfer of heat from the absorption acid to high pressure boiler feed water that is fed to a waste heat boiler where steam is generated by transfer of heat from sulfur dioxide combustion gas. Heat is transferred from the absorption acid to a boiler feed water stream in an array of heat exchangers that are in series with respect to the flow of both the boiler feed water stream and the absorption acid stream, and with respect to which array the absorption acid stream and the boiler feed water stream flow countercurrently. Boiler feed water is allowed to flash in a reduced pressure zone in the boiler feed water path, thus preserving a Δt throughout the array of heat exchangers for recovering heat from the absorption acid in water fed to the high pressure boiler.

    摘要： A contaminant gas is removed from a feed gas in two absorption and stripping circuits operated in tandem. The gas is first passed through a rich gas absorber producing a rich absorption liquor from which contaminant gas is stripped in a rich liquor stripper. A lean gas exiting the rich gas absorber is passed through a lean gas absorber, producing a lean absorption liquor from which contaminant gas is stripper in a lean liquor stripper. Regenerated absorption media exiting the respective strippers are recirculated to the respective absorbers.
