We studied the absorption of SO2 from mixtures with N-2 into limestone slurries. The reactor used was a stirred tank with an almost flat gas-liquid interface of area 67.7 x 10(-4) m(2) at 400 rpm, operated in gas-phase continuous operation mode and batchwise for the slurry. The operating temperatures used were 20degreesC and 40degreesC, the content of limestone in the initial slurry was 1, 3 and 5 wt% and the volume fraction of SO(2)in the gas mixture at the inlet to the reactor ranged from 4% to 10%. We determined the overall gas-side SO2 transfer coefficient, obtaining values of 0.104 and 0.083 mol/s/m(2)/bar at 20degreesC and 40degreesC, respectively. By taking into account the individual gas-side SO2 transfer coefficient and estimating the enhancement factor, we were able to determine the thickness of the interfacial liquid film, 45 and 58 mum at temperatures of 20degreesC and 40degreesC, respectively, and the SO2 physical absorption coefficient, 3.27 x 10(-5) and 4.01 x 10(-5) m/s at 20degreesC and 40degreesC, respectively. The results obtained are comparable with those reported in previous studies, both by ourselves and by other authors.
