Mathematical modeling and simulation of acidification process for sugar extraction

In the present work, a mathematical model for an acidification process of water used for the diffusion operation in the beet sugar refineries is developed. This model is based on masses balances taking into account the main chemical reactions occuring. It was validated in dynamic state, experimentally, by carrying out tests on an industrial process. Indeed, it was simulated, in steady state, to determinate of process parameters operation, and in dynamics, to study the behavior in transient state. Dynamic simulation was realized by solving the differential equations of the model using the Runge-Kutta method, and while carrying out on the real processes the various disturbances that have the echelon form. The results obtained are satisfactory and has showed that the model is valid and can be used for the pH control
