Abstract

The dynamic modeling of sugar extraction process from beet was carried out and the resulting first order partial differential equations written for three main constituents of the system (Sugar, Non-sugars and Water), were solved numerically by an implicit finite difference algorithm. The model is able to predict the axial concentration profiles and the process variables such as Brix, Purity and the percentage of sugar and non-sugar components extracted during the process at the exit streams. The results of the model were compared with the experimental data obtained from an industrial plant and a close agreement was observed. In an industrial extraction plant, it is always desired to maintain a constant and uniform flow of materials entering the tower to ensure that the properties of the effluent streams would not be changed. To achieve this, a Proportional Integral (PI) Controller is installed in the process to control the liquid level in the tower.
