    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.

    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.
