Conceptual design of a packed bed for the removal of SO2 in Oxy-fuel combustion prior to compression

The influence of L/G ratio is primarily on the liquid phase mass transfer coefficient and secondarily on the interfacial wetted area. A higher L/G ratio results in a shorter column height but a higher HCO3− concentration. Therefore, the L/G ratio should be optimized based on both reasonable column height and HCO3− concentration. Overall, this paper sheds light on the design of the scrubber for the treatment of SO2 from Oxy-fuel combustion.
