Abstract
A model has been developed which represents gas absorption into a slurry accompanied by chemical reaction with solute from sparingly soluble fine particles. The rate of absorption into a slurry seemed to be higher than that into a saturated solution containing no reactive particles, as reported previously by others; but our theoretical estimates disagreed with previous results, especially under conditions of instantaneous reaction. A characteristic length determined geometrically by the size and concentration of the particles is a factor in estimating the effect of particle dissolution on the rate of gas absorption, but the mass transfer coefficient for particle dissolution need not be known.
