Item Isothermic Gasification Octave(INSTITUTO DE TECNOLOGIA, 2015) MATIAUDA, Mario; DE LEÓN BENÍTEZ, Juan B.; ARTEAGA, Luis Ernesto; FREAZA, Nora; RIVERO, Marta; YACHECEN, Carlos; Eduardo de Magalhães BragaGasification is a process of thermal conversion where solid biomass (sawdust pellets) is transformed into gas by partial oxidation at high temperatures. The model is based on the two-phase theory (bubble - emulsion), suitable for predicting experimental results in reactions occurring in fluidized beds. The model simulation includes mass and energy balances and hydrodynamic studies, with assumptions such as isothermal process behavior.Item Fluidized bed combustion of sawdust pellets(INSTITUTO DE TECNOLOGIA, 2015) MATIAUDA, Mario; BENÍTEZ, Juan B. de León; FREAZA, Nora; RIVERO, Marta.; Jandecy Cabral LeiteThe study investigates the combustion of sawdust pellets in a fluidized bed, aiming at the energy recovery of solid waste in bioethanol production. Samples of pine and palo blanco were analyzed, focusing on the devolatilization stage and primary fragmentation. Results showed significant differences in thermal behavior and fragmentation between the species, with pine exhibiting less fragmentation and more consistent residues. The theoretical model used predicted devolatilization times, validated experimentally, highlighting the influence of bed temperature and particle diameter.Item Isothermic Gasification Octave: Gasificação isotérmica modelada e simulada com Octave(INSTITUTO DE TECNOLOGIA, 2015) MATIAUDA, Mario; DE LEÓN BENÍTEZ, Juan B.; ARTEAGA, Luis Ernesto; FREAZA, Nora; RIVERO, Marta; YACHECEN, Carlos; Manoel Henrique Reis Nascimento, Dr.Gasification is a thermal conversion process where solid biomass (sawdust pellets) turns into gas by partial oxidation at high temperatures. The model is based on the two-phase theory (bubble-emulsion), suitable for predicting experimental results in fluidized bed reactions. It includes mass and energy balances, and hydrodynamic studies. The simulation is implemented in Octave with a graphical user interface, enabling predictions of the distribution and concentrations of gas species during the process.Item 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 SilvaCalcination 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.
