Auditoria energética a uma instalação industrial têxtil

Auditoria energética a uma instalação industrial têxtil

Abstract

De acordo com o relatório da Organização Mundial para a Cooperação e Desenvolvimento Económico (OCDE), no ano de 2019, verificaram-se, novamente, aumentos nos consumos mundiais de energia primária e nas respetivas emissões de Gases com Efeito de Estufa (GEE). Torna-se, assim, por demais evidente que o estudo da eficiência energética desempenha um papel de enorme responsabilidade na racionalização destes valores. A dissertação que se apresenta aborda a execução de uma auditoria energética a um estabelecimento industrial têxtil concreto, inserido no subsetor de branqueamento e tingimento têxtil, abrangido pelo Sistema de Gestão dos Consumos Intensivos de Energia (SGCIE). Nas condições previstas pelo Decreto-Lei n.˚68-A/2015, torna-se obrigatória a execução de uma auditoria energética, visto que a instalação alvo apresentou, no ano civil de 2019, um consumo anual de energia primária de 3 454 toneladas equivalente de petróleo (tep). A caracterização energética da instalação e a identificação de potenciais programas de investimento em sistemas energéticos, conducentes ao aumento da eficiência energética e/ou redução da fatura energética da empresa, foram as principais finalidades deste estudo. De modo a efetuar-se a auditoria em questão, tornou-se essencial a realização de um enquadramento bibliográfico, abordando-se o consumo de energia nacional e mundial, bem como a respetiva legislação atualmente em vigor. De seguida, adotou-se a metodologia que seria a base do projeto, sendo esta etapa sucedida pela elaboração de um caderno subsetorial, referente à atividade empresarial em que a instalação alvo da auditoria se insere. Posteriormente, tiveram lugar etapas fundamentais ao processo de auditoria energética, nomeadamente a recolha de dados e planeamento da intervenção, os levantamentos e medições de campo e o tratamento e análise de toda a informação obtida. Por fim, com vista na implementação de um processo contínuo e eficiente de gestão da energia consumida na instalação e de forma a alcançarem-se os objetivos legalmente exigidos, foram ainda identificadas Medidas de Utilização Racional de Energia (MURE), destacando-se o dimensionamento de uma Unidade de Produção para Autoconsumo (UPAC) e a reativação do Sistema de Recuperação de Calor dos Efluentes Quentes da Tinturaria, constituintes do Plano de Racionalização dos Consumos Energéticos (PREn) da instalação auditada.

According to the report of the Organization for Economic Co-operation and Development (OECD), in the year of 2019, there were, once again, increases in the world’s consumption of primary energy and in the respective emissions of Greenhouse Gases (GHG). It thus becomes all too clear that the study of energy efficiency plays an enormously responsible role in the rationalization of these values. The dissertation that is presented addresses the execution of an energy audit to a textile industrial establishment, inserted in the textile bleaching and dyeing subsector, covered by the Intensive Energy Consumption Management System (SGCIE). According to the Portuguese regulation conditions, provided by the Decree-Law nº 68-A/2015, it is mandatory to execute an energy audit, since the targeted industrial plant, in the calendar year of 2019, presented an annual primary energy consumption of 3 454 tonnes of oil equivalent (toe). The industrial plant’s energy characterization and the identification of potential investment programs in energy systems, that would lead to an increase in the overall energy efficiency and/or a reduction in the company’s energy expenses, were the main purposes of this study. In order to carry out the energy audit mentioned, the study of a bibliographic framework became essential, addressing the national and global energy consumption, as well as the respective legislation currently in force. Then, the methodology that would be the basis for this project was adopted and this step was followed by the elaboration of a subsector notebook, referring to the business activity in which the audited industrial plant is inserted. Subsequently, fundamental steps were taken so that audit the targeted industrial plant, namely the collection of data and intervention, the field surveys and measurements and the treatment and analysis of all the obtained information. Finally, with a view to implement a continuous and efficient management process of the industrial plant’s energy consumption, and in order to achieve the required legal objectives, Rational Energy Use Measures (MURE) were also identified, emphasizing the project of a Production Unit for Self-consumption (UPAC) and the Reactivation of the Dyeing’s Hot Effluents’ Heat Recovery System, as part of the audited industrial plant’s Energy Consumption Rationalization Plan (PREn).
