AUMENTO DA EFICIÊNCIA DE DESSULFURAÇÃO DO GUSA LÍQUIDO EM UM REATOR KANBARA

Abstract

Mathematical and physical modeling of Kanbara process, which takes in consideration the particle size of the reagent, the shape, depth of immersion, rotation speed and positioning of the mechanical agitator have been used to assess the efficiency of desulfurization. The nature of the dispersion of the reagent has been studied through physical modeling, and the need to incorporate its spatial distribution in the model is discussed. Theoretical and practical implications of the decentralization of the impeller are also addressed. Desulfurization results taken from an industrial plant are in good agreement with a mathematical model that disregards the major complexities of the process. This model has been used to highlight the effects of rotational speed and particle size.
