Abstract:
Wet Biochemical Flue Gas Desulphurization technique (WB-FGD) is combined both catalyst of transition metal with microbial metabolize to achieve flue gas desulphurization. In the self-designed device of power plant flue gas desulphurization, study the desulphurization kinetics according to the absorption solution pH, Fe 3 + concentration, inlet concentration of SO 2 , temperature and other factors. The results show that: Concentration of Fe 3 + is the most critical factors in the desulphurization process, the desulphurization efficiency is decreased with the increasing of Fe 3 + concentration, which in the range of 0~0.01mol·L -1 , and the desulphurization efficiency do not change significantly with the further increasing of the concentration of Fe 3 + .the desulphurization efficiency is decreased with the increasing concentration of H + when pH of the solution in the range of 1.5~3.5. The efficiency of desulphurization decrease with the increasing concentration of SO 2 , which in the range of 1145-3432mg·L -1 . The oxidation rate increase with the increasing temperature at 20~40°C.The kinetic equation and controllable parameters of changes of Fe 3 + concentration are obtained according to the experimental data in WB-FGD.
