Sulphur dioxide absorption in air-lift-tube absorbers by sodium citrate buffer solution

Furthermore, the influence of oxidation on the SO2-removal efficiency was measured using SO2/N2 mixture instead of SO2/air mixture; the effect of stoichiometric ratio was investigated and the SO2 removal in one and two stages of tube absorbers was measured. The performance of the laboratory and pilot scale ALT absorbers was compared with that of other laboratory and pilot size absorption columns and of some non-regenerative methods.
