Abstract
PURPOSE:To control the generation of ammonium sulfate fume by bringing an absorbing liq. contg. NH4OH into contact with exhaust gas contg. SOX, desulfurizing to produce (NH4)2SO3 and blowing air for oxidation into the absorbing liq. contg. the (NH4)2SO3. CONSTITUTION:The exhaust gas 2 contg. SOX is introduced to an absorber 1 and desulfurized by spraying the absorbing liq. 3 contg. NH4OH from a spray 5 to produce (NH4)2SO3. Then, a part of the absorbing liq. 3 is sent to a oxidation tower 7 to convert (NH4)2SO3 into (NH4)2SO4. On the bottom part of the absorber 1, an air pipe 9 for blowing the air for oxidation into the absorbing liq. 3 is equipped and the air is blown up from holes 8 to convert (NH4)2SO3 into (NH4)2SO4. Thereby, the concn. of (NH4)SO3 is reduced and the partial pressure of SO2 in the liq. is lowered to control the generation of ammonium sulfate fume.
