KVT - Model OXYSULF SAR -Wet Sulfuric Acid Plant

For the spent acid and sulfate regeneration the OXYSULF SAR is used. The spent acid with the fuel gas is fed into a special designed combustion chamber to form SO₂. The acid together with fuel gas is fed into the burner through compressed air and ultrasonic atomizing. For special applications there is the possibility to use H₂S gas or S feed instead of fuel gas to reduce energy cost. Depending on the acid composition and possible impurities a hot gas filter after the combustion chamber maybe required to remove the solid impurities from the SO₂ gas stream. After the hot gas filter, the gas stream is treated with an OXYSULF HK plant where the conversion of SO₂ to SO₃ and then the hydrolysis to sulfuric acid takes place. The clean gas is discharged to the atmosphere through the main stack.
