Özet

The paper presents a model of the reaction between SO₂ and trona based slurries. Experimental findings relevant to the desulfurisation in a spray dryer were compared with the proposed mathematical model and were found in good agreement. It is observed that at high stoichiometric ratios, the diffusion of SO₂ from the gas bulk to the droplet interface is dominant for absorption and with decreasing stoichiometric ratio the absorption efficiency decreases. An increase in the temperature also causes a decrease in absorption efficiency. At the stoichiometric ratio (Na/S = 2), SO₂ removal efficiency was found to be around 90%.
