Simulação da Produção na Precipitação Hydro Alunorte

Abstract

The simulator of solids concentration in the production of the precipitation process is based on a model made by mass balances in tanks, where it was necessary to act to boost the level of production in the competitive market. The simulator considers nucleation, growth, breakdown, agglomeration, solubility, and crystallization in precipitators. The model was used to solve a significant problem in the process variable (mass concentration in the precipitation production chain) due to its large variations and losses, thus predicting production behavior throughout the circuit to its final stage. Numerical and laboratory results were obtained and compared, allowing a critical evaluation of this solution methodology.
