Abstract: This paper deals with the study of gas-liquid mass transfer, coupled with chemical reactions and liquid-solid mass transfer, coupled with crystallization. Sodium bicarbonate is a substance that is produced in the middle stages of the soda ash production process. In this precipitation process, carbon dioxide gas is continuously injected into the bubble column reactor which contains carbonate and bicarbonate solutions. In this mathematical modeling, a mole balance has been introduced by means of flow and components through a bubble column, also used for solid phase mass transfer and mass transfer between gas and liquid phases. The mathematical model can predict the effects of several parameters on the production of sodium bicarbonate crystals, and the conversion of carbon dioxide, and crystal size distribution. Computed mathematical simulator model results with experimental results for validating the model, and investigated effects of different parameters on carbon dioxide absorbent and sodium bicarbonate product, and crystal size distribution.
