Abstract

Integrated absorption-adsorption for waste free desulfurization of gases from SO2 in a bubble tray column is presented. The method includes physical absorption of SO2 with water and chemical adsorption of HSO3-from the water solution by particles anionite. The two steps method is integrated in one apparatus-a bubble tray column. This method is regenerative and the regeneration is made with solution of ammonium hydroxide. The further step for utilization of the obtained (NH4)2SO3 and (NH4HSO3) is by using HNO3) for production of concentrated SO2 (gas) and NH4NO3 (solution). Convection-diffusion and average concentration models are presented, which are used to describe absorption and adsorption processes. A comparison of the calculated trough the mathematical model and the experimental data is shown.
