Abstract The report gives results of a study of the absorption of SO2 from an SO2/N2 gas mixture into water and lime solutions and slurries (in a short wetted wall column at approximately 1 atmosphere and 25C). The mole per cent of SO2 in the gas was varied from 0.03 to 0.37. In solutions of calcium hydroxide greater than 0.01 g mole/liter and in slurries, the system appeared to be gas absorption accompanied by an 'infinitely' rapid irreversible second-order reaction in the liquid phase. The only effect of the solid in the slurries was to increase the absorption capacity. In water, the system appeared to be gas absorption accompanied by a fast reversible hydrolysis reaction in the liquid phase. The major resistance to gas absorption at these concentration levels was found to be in the gas phase. At the lowest concentrations studied, the system was gas-phase controlled.
