Removal Characteristics of SO2 in Absorbents Internal Circulating Desulfurization Equipment
SO2 gas present in the atmosphere is generated mainly through the industrial processes of fuel combustion, especially those of oil and coal combustion where the discharge rates of SO2 gas are the highest. Herein, we consider that the introduction of new desulfurization technology for efficient removal of high content of SO2 gas from industrial discharge sources is necessary. In our study we have conducted the tests using the absorbent internal circulating Turbo-FGD unit to identify the most efficient of three applied absorbents for the SO2 removal at high flue gas temperatures 300 to 400℃ and to evaluate their performance. By maintaining the flue gas high temperature and fluidizing the absorbents and bed materials, this unit has proven the ability of keeping the SO2 removal rate high while preventing the absorbent to adhere on the internal wall of the desulfurization unit. The pressure drop and SO2 removal efficiency characteristics were closely investigated by varying test parameters such as Ca/S mole ratio, water injection feed rate, flue gas flow rate, absorbent material, the amount of bed material, SO2 inlet concentration and reaction temperature.
