BALANÇO DE MASSA E ENERGIA EM CALCINADOR DE LEITO FLUIDIZADO EM UMA REFINARIA DE ALUMINA

Abstract

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.
