Resumen
QUINTANA-HERNANDEZ, P. A.; URIBE-MARTINEZ, B.; RICO-RAMIREZ, V. y BOLANOS-REYNOSO, E.. Comparative analysis of power law type and diffusion-integration kinetic equations in batch cooling of sugar cane. Rev. Mex. Ing. Quím [online]. 2008, vol.7, n.2, pp.171-182. ISSN 1665-2738.
In this work, the sugar cane cooling crystallization process is analyzed. Simulation results obtained with different kinetic equations (power-law type, PLT and diffusion-integration equations, DIE) are compared against experimental results. The crystallization process is modeled by a set of algebraic-integral-differential equations that represent the mass, energy and population balances; and it is solved using the method of lines. The results show that PLT equations generate values for the state variables that are closer to experimental information than results obtained with DIE. Further, it is clear that DIE equations require parameters that change according to process conditions.
