Item Melhor aproveitamento da energia elétrica na indústria(INSTITUTO DE TECNOLOGIA, 2014) SOARES, Gerdson Tanaka; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota; Profª. Drª Aline Maria Meiguins de LimaThis paper presents a proposal for an industrial energy management system focused on low-cost actions, based on measurement, recording, control, and automation. Through a case study in a plastics industry located in the Industrial Pole of Manaus, it was possible to demonstrate energy savings of up to 35.5%, using the Measurement and Verification (M&V) methodology. The study highlights the importance of integrated management as a tool for energy efficiency, with positive impacts on productivity, cost, and sustainability.Item Previsão da Eficiência de uma Usina Geradora de Energia Elétrica(INSTITUTO DE TECNOLOGIA, 2014) SILVA, Wagner Ferreira; CAMPOS, Lucila Maria de Souza; MIGUEL, Paulo Augusto Cauchick; MAGALHÃES, Edilson MarquesThe study examines the efficiency reduction of motors in an electricity-generating plant from 2001 to 2013, forecasting efficiency up to 2020. Methods such as exponential, logarithmic, linear, and ARIMA were applied using tools like Excel and SPSS20. Results indicated consistency across models, demonstrating the effectiveness of simple solutions for long-term forecasts. The research underscores the significance of forecasting for strategic and operational planning in thermoelectric plants.Item Redução do consumo de energia elétrica em Manaus através de medidas de eficiência energética em climatização industrial(INSTITUTO DE TECNOLOGIA, 2010) SILVA, Jorge Lúcio da; LEITE, Jandecy Cabral; COSTA JUNIOR, Carlos Tavares da; Jandecy Cabral LeiteThe article evaluates the impacts of reducing electricity consumption in a company at the Manaus Industrial Hub (PIM) through the optimization of energy efficiency (EE) in industrial air conditioning systems, using Fuzzy Logic as a basis. Measures such as replacing low-efficiency air conditioners with high-efficiency equipment, controlling external heat sources, checking pipeline losses, and adjusting thermal comfort temperature were implemented. The results showed significant reductions in energy consumption and contracted demand, demonstrating the economic and technical feasibility of the adopted measures.Item Advantages of applying composite material to replace metal alloys in aviation(INSTITUTO DE TECNOLOGIA, 2015) BARROS, Marcelo André Santiago; FUJIYAMA, Roberto Tetsuo; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesComposite materials were used by early agricultural societies and their adoption has been driven by military technological needs. High fuel costs and strict environmental regulations have increased the demand for this technology in the civil sector. This article presents the application advantages of composites in aircraft structures, especially regarding weight reduction, lower operational costs, and environmental, social, and economic impacts. The research includes literature review, experimental studies, and comparisons with traditional metal alloys.Item Aspectos Importantes na Utilização de Bombas Centrífugas em Velocidade Variável para a Redução do Consumo de Energia(Instituto de Tecnologia, 2006) MESQUITA, André L. Amarante; SILVA, Lázaro J. S. da; ABRAHAM JÚNIOR, Otávio; PEREIRA, José Almir; R. SILVA, Aldo Cezar P.; BATISTA, Clauderino da SilvaThe study examines the use of variable speed centrifugal pumps as a solution to reduce energy consumption in water supply systems. It covers theoretical principles, technological aspects, and economic feasibility, employing frequency inverters to adjust flow according to demand. Two case studies illustrate the method's effectiveness: parallel pump operation and tank level control. Results show significant energy savings with short financial payback, emphasizing the need for technical and economic analysis for implementation.Item Análise Exergética no Processo de Aquecimento de Licor Pobre em uma Refinaria de Alumina(Instituto de Tecnologia, 2015) SANTOS, Antonio Marcos Nascimento dos; BATISTA, Clauderino da SilvaThis study identifies energy loss points through exergy balances in heat exchangers used to heat spent liquor in the Bayer process for alumina extraction. Energy and exergy balances were performed in exchangers using live steam and regenerative steam, with significant losses identified in exchangers 4 and 5. The exergoeconomic analysis highlighted financial losses, providing a foundation for energy recovery actions and operational cost reduction.Item Automação de Recuperadora de Bauxita para Melhoria da Eficiência Energética(Instituto de Tecnologia, 2015) SILVA, Marcelo Siqueira da; JUNIOR, Petrônio VieiraThis study describes the development of automation for a bauxite reclaimer at Hydro Alumina refinery in Barcarena-PA, aiming to improve the machine's energy efficiency. Automation was achieved through the installation of position sensors and the implementation of automatic operation programming, leading to reduced energy costs, lower maintenance demands, and extended equipment lifespan. The return on investment was estimated at less than three years.Item Análise Energética do Sistema de Resfriamento de uma Planta de Compressores de Ar Modelo ZH9000(Instituto de Tecnologia, 2015) FREIRE, Wildemar de Aguiar; BRAGA, Eduardo de MagalhãesThis study evaluates the cooling system of ZH9000 air compressors in an alumina refinery, addressing overheating and energy inefficiency. The proposed solution involves plate heat exchangers to isolate the water circuit, minimizing contamination and enhancing thermal performance. Findings suggest annual savings of R$600,000 and lower maintenance costs, with a 10-month payback period.Item Análise da Eficiência Energética dos Sistemas de Climatização Centralizada: Estudo de Caso no Polo Industrial de Manaus(Instituto de Tecnologia, 2016) WADA, João Koyty Oji; RODRIGUEZ, Jorge Laureano MoyaThis dissertation examines the energy efficiency of centralized air conditioning systems in an industry at the Industrial Polo of Manaus (PIM), comparing direct expansion (air) and indirect expansion (water) equipment. The study shows that replacing screw chillers with centrifugal chillers reduces electricity consumption by up to 40%, with a quick return on investment (payback).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.
