Description The phenomena of precipitation, driven by a reaction, in a gas-liquid system is studied, theoretically as well as experimentally, using the carbon dioxide-calcium hydroxide-calcium carbonate system. Experimental data was generated by contacting carbon dioxide gas with aqueous calcium hydroxide solution in model gas-liquid, stirred contactor, at different operating parameters. The particle-size distribution of the precipitated calcium carbonate particles was found using microscopy and optical image analysis techniques. A modeling approach, based on Higbie's penetration theory, for the diffusion-reaction-precipitation system, combined with population balances for the particles, has been proposed. The model computations and the experimental results agree reasonably well.
