    Aplicação do Filtro com Reamostragem por Importância Sequencial (SIR) na Simulação de Dados de Processo de Precipitação: Desenvolvimento de um Aplicativo Computacional para Auxílio na Tomada de Decisão em Refinaria de Alumina
    (Instituto de Tecnologia, 2015) AZEVEDO JÚNIOR, Cleto Maués; BATISTA, Clauderino da Silva
    This study describes the development of a computational application based on mathematical models of mass balance and particle filters to simulate the precipitation process in the Bayer circuit. The goal is to provide a tool to assist process engineers in daily decision-making, enhancing the control of productivity and alumina quality. Simulated results were compared with real plant data, showing average relative errors of 4.7%, validating the model's effectiveness.

    Simulação da Produção na Precipitação Hydro Alunorte
    (Instituto de Tecnologia, 2015) MACIEL, Milton Jasonn Neves; BATISTA, Clauderino da Silva
    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.
