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.
BALANÇO DE MASSA E ENERGIA EM CALCINADOR DE LEITO FLUIDIZADO EM UMA REFINARIA DE ALUMINA
(Instituto de Tecnologia, 2016) CRUZ, Victor César Ribeiro da; BATISTA, Clauderino da Silva
Calcination is the final step in the alumina production process, where aluminum hydroxide is subjected to high temperatures to remove surface and chemically bound water. This study conducted the mass and energy balance of a calcination unit, evaluating the impact of key control variables on energy efficiency. The results showed that fuel consumption is influenced by cyclone efficiency, furnace temperature, hydrate moisture, and atomization steam flow, identifying opportunities for process improvement.
