Experimental study of simultaneous removal of CO2 and SO2 in a spouted bed reactor

Abstract

Simultaneous absorption of CO2 and SO2 was analyzed using the Taguchi method for NaOH solution in a powder particle spouted bed reactor. Experimental results revealed that CO2 removal efficiency increased as the inlet CO2 concentration inlet gas temperature and Na/C molar ratio increases and decreases as the inlet SO2 concentration and gas flow rate decreases. A 68.564% maximum CO2 removal efficiency was achieved under optimal conditions of 13.55 m3/h gas flow rate 1400 Μg/g of flue gas for inlet CO2 concentration 0.0 Μg/g of flue gas for inlet SO2 concentration 200 °C and 2.4 Na/C molar ratio.
