Abstract(s)
O conceito Water-Energy Nexus contribui, cada vez mais, para demonstrar que a água e
a energia são recursos que estão inevitavelmente interligadas no quotidiano da nossa
sociedade. A utilização da água é visível nos processos de produção de energia elétrica,
e.g. na movimentação de turbinas hidráulicas, aproveitando a energia potencial gravítica
armazenada nas albufeiras ou em centrais termoelétricas na produção do vapor que faz
rodar os geradores. É também possível encontrar exemplos de utilização da energia
elétrica em processos que envolvem água, no transporte, distribuição e armazenamento,
na utilização de bombas para captação e finalmente no tratamento, do líquido mais
precioso para vida na Terra, de modo a o devolver à natureza, com o mínimo impacto
possível.
Este documento começa por descrever a interligação da água com a energia no passado.
Em seguida, são descritas práticas atuais que visam otimizar a utilização destes dois
recursos.
A temática da Water-Energy Nexus é atualmente alvo de estudos que visam adotar as
novas tecnologias para obter os objetivos finais, bem como a formulação de diretrizes e
normalização desde a distribuição, à pegada como medidor de desempenho e na gestão
dos vários sistemas de energia. Esta dissertação analisa, portanto, a normalização
existente no meio e procura as suas fragilidades de modo a incrementar o conceito.
É proposta uma Metodologia para a Localização Exata de Fugas de Água através de um
equipamento eletroacústico, para que deste modo os processos da água se tornem mais
eficientes e se desperdice menos água, e por consequente, menos energia no tratamento
dessa mesma água. E ainda uma Metodologia para Controlo Pró-Ativo de Perdas de Água
e Energia que quantifica a energia que é possível poupar com a reparação dessas mesmas
fugas.
In the Water-Energy Nexus, water and energy are increasingly intertwined in our daily lives as a society. Whether in the sense of water to energy, in the processes of generating electricity from the movement of hydraulic turbines, taking advantage of the gravitational potential energy in reservoirs or pipelines, or even in thermal power plants using steam to turn the generators. Whether in the sense of energy for water, in transport processes, distribution and storage, in the use of pumps for capturing and finally in the treatment, of the most precious liquid for human life, in order to return it to nature with the least possible impact. This document seeks to understand how water was interconnected with energy in the past, and to describe implemented projects that optimize the use of these two resources. The Water-Energy Nexus is increasingly the subject of studies for new technologies, as well as the formulation of guidelines and standardization from distribution to footprint as a performance meter, and in the management of various energy systems. This dissertation analyses the existing standardization in the medium and looks for its weaknesses to increase the concept. A Methodology is proposed for the Exact Location of Water Leaks through electroacoustic equipment, so that in this way the water processes become more efficient and less water is wasted, and consequently, less energy in the treatment of water. And also a Methodology for Proactive Control of Water and Energy Losses that quantifies the energy that can be saved by repairing these leaks.
