Title: Desulfurization of waste gas
Inventor: ITOU TADAATSU
IPC: B01D53/77
Filed: 1984-06-28
Abstract: PURPOSE:To improve rate of desulfurization and to remove SO2 inexpensively by adding CaCO3, Ca(OH)2 or CaO within a range of specified molar ratio to liquid absorbent for SO2. CONSTITUTION:Waste gas contg. SO2 is guided to an absorption tower 1 and the SO2 is absorbed and removed. The amt. of the liq. absorbent to be fed to the absorption tower 1 is so adjusted that the pH of the liq. absorbent is held at a constant value by measuring with a pH meter 14. The flow rate of Ca(OH)2 slurry having a specified concn. is controlled, and the flow rate of the CaCO3 slurry is controlled so as to keep a fixed proportion to the flow rate of the Ca(OH)2 slurry. By this method, the molar ratio of CaCO3 to Ca(OH)2 to be fed to the absorption tower is held between 2/1-1/6 so as to attain the max. desulfurization rate. By this arrangement, the concn. of (HSO3<->+SO3<->) in the liq. absorbent is increased, and the desulfurization rate is improved.
