| From considerations of mass, energy and population balances, equilibrium relationships and kinetic data, a model was prepared to predict the performance of an industrial cooling crystallizer as used in the cane sugar industry. Using given starting conditions, a stepwise procedure was used to predict the variation of performance criteria during the cooling crystallization of low grade massecuites. This simulation was validated using available experimental data. The effect of changes in various operating variables was evaluated, and operating policies were formulated. In particular an optimum cooling programme has been proposed, its applicability to pure and synthetic sucrose solutions established and its implementation to industrial sugar crystallizers is discussed. A method of reducing massecuite viscosity by pre-spinning of the massecuite is considered as an example, and its consequent effect on minimum operating temperature and exhaustion are discussed. Work was also carried out on the pressure drop through continuous crystallizers. Correlations in terms of the Lagrange Number have been proposed to characterise the head loss through orifices and over weirs. | |
