In this study, the mass transfer accompanied by an instantaneous irreversible chemical reaction in a slurry bubble column containing sparingly soluble fine reactant particles has been analyzed theoretically. Based on the penetration theory, combining the cell model, a one-dimensional mass transfer model was developed. In the model, the effects of the particle size and the particle dissolution near the gas-liquid interface on the mass transfer were taken into account. The mass transfer model was solved and an analytical expression of the time-mean mass transfer coefficient was attained. The reactive absorption of SO2from gas mixtures into Mg(OH)2/water slurry was investigated experimentally in a bubble column reactor to validate the mass transfer model. The results indicate that the present model has good predicting performance and could be used to predict mass transfer coefficient for the complicated gas-liquid-solid three-phase system with an instantaneous irreversible chemical reaction.

Instead of solving a set of N nonlinear equations (as has been proposed by the author and his coworker), the problem may be solved iteratively as a linear one. The proposed method converges rapidly and the number of iterations is practically constant regardless of the number of stages in countercurrent cascade N and the degree of nonlinearity of equilibrium formula. The method proved to be suitable for computation on desk-top calculator.
