The absorption rate into slurry in a gas-sparged stirred vessel under continuous operation was investigated experimentally and theoretically. The gas–liquid specific interfacial area and volumetric mass transfer coefficient were determined experimentally. The absorption rate of CO<SUB>2</SUB> into an aqueous slurry of Ca(OH)<SUB>2</SUB> particles and the power required for agitation were measured simultaneously in a gas-sparged stirred vessel under continuous operation.<BR>A film theory model for the absorption rate was proposed, which was valid for the case where the concentration of the solute gas in the bulk of the slurry absorbent could not be assumed to be zero. The observed rates of absorption into the slurry agreed well with the predicted values by the present model both in the range of high solid concentration of Ca(OH)<SUB>2</SUB> where the model of Sada <I>et al.</I> is valid and in the range of low solid concentration where the modified enhancement factor is less than unity.
