15. Study of cost minimization of separation process of a multi components gas mixtures through the hollow fiber membrane / Estudo da minimização do custo de um processo de separação de misturas gasosas multicomponentes atraves da membrana de fibra oca
The separation of gas mixtures is made under the objective of obtaining one or more representatives in the highly pure form. Four methods can be used in gas separation: absorption, adsorption, distillation cryogenics and membranes. The economy of the process will determine which method will be used in a specific application (Scott, 1995). The modem era of ga

17. AnÃlise energÃtica experimental e estudo da viabilidade econÃmica de um grupo gerador de 30 kWe A gÃs natural em diferentes nÃveis e tipos de cargas elÃtricas
Due to the lack of investment in the Brazilian electricity sector, together with the increment of the economy, there is a great possibility of new electricity rationing in 2007. This energy shortage imposes that the companies, which do not intend to have a reduction in their production capacity, supply their own electricity. One of the main options is the el

18. ANÁLISE DE UM SISTEMA DE PRODUÇÃO SIMULTÂNEA DE ELETRICIDADE, FRIO E CALOR / ANALYSIS OF A SYSTEM FOR THE SIMULTANEOUS PRODUCTION OF ELECTRICAL ENERGY, HEAT AND COLD
The simultaneous production of electric energy, heat and cooling capacity from the primary fuel burning on a heat engine (trigeneration) can emerge as a promising strategy, from the energy and project points of view, mostly, in food and chemistry industries. The present work describes the experimental study of a vapor compression system for chilled water pro

19. Activities based cosi (ABC) applied the electrification cooperatives: a case study / Custeio baseado em atividades (ABC) aplicado a cooperativas de eletrificação: um estudo de caso
The cost has been considered like an inductive element in decisions of national energy politics in arder to make possible the increment of expansion capacity of generator park of Brazilian economy. The electric net cost will not reflect only investors, but they will allow to apply the resources in the electric energy distribution, mainly in the urban and poo

20. A Energia Térmica e o Paradoxo da Eficiência Energética: Desafios para um Novo Modelo de Planejamento Energético / The Thermal Energy and the Energy Efficiency Paradox: Challenges for a New Paradigm of Energy Planning
The electrical generation model of Brazil has a peculiar characteristic regarding other countries. Its large hydropower capacity allowed the indiscriminate use of the electricity for several kinds of end uses. However, with the transition of the hydroelectric generation model for a mixed generation model, a new paradigm of energy efficiency appears. The elec

24. Gerenciamento da demanda residencial de eletricidade : o caso de centros urbanos da Região Amazonica
The first oil crisis in 1973 marks the beginning of a new era in the intemational economy. One of the outcomes was the decoupling effect noted between economic growth and energy demand, forcing a revision of traditional models of energy planning. In the context, the Demand Side Management (DSM) became a very important planning instrument for many electricity
