Experiments were performed on the packed tower with 150mm diameter and 2800mm high to study the wet flue gas desulfurization continuously. The results shows that the suitable conditions for the SO2 absorption process of 0.3mol•L-1 ethylenediamine/phosphoric acid and ethylenediamine/boric acid solutions: pH value was 6.0~7.0, liquid-gas ratio was 0.82L•m-3. The import SO2 concentration and the flue gas flow were separately at 500×10-6~3100×10-6 and 110m3•h-1~150m3•h-1, the desulfurization efficiency exceeded 97%. Under the same conditons, ethylenediamine/boric acid has a better desulfurization and was more suitable for the flue gas desulfurization in a wider fluctuation.
