Abstract(s)
O presente trabalho foi realizado no âmbito da disciplina de Dissertação/Estágio, do Mestrado de Engenharia Química, no ramo de Energia e Biorrefinaria do ISEP, na empresa Continental – Industria Têxtil do Ave durante o período de 8 meses.
O principal objetivo deste trabalho foi a implementação de um sistema de aquisição de dados, MESSDAS e PME (Power Monitoring Expert), softwares que visam o controlo e gestão dos consumos energéticos. Paralelamente foi feita a avaliação da implementação do sistema ECO VAC, nos consumos de gás natural das estufas da máquina de impregnar tela.
Para a implementação dos sistemas de gestão, foi feito um estudo prévio do seu funcionamento assim como a otimização das comunicações existente de forma a eliminar as falhas que ocorriam. O PME ficou funcional para os analisadores de energia elétrica, estando os restantes ainda em estudo para avaliar a melhor forma de comunicação com o servidor. O ESSDAS, devido à ocorrência constante de erros, proveniente da comunicação em paralelo dos dois softwares, ficou em standby. É então necessário determinar a parametrização correta para que o equipamento de medição possa comunicar com ambos os sistemas de gestão sem que haja falhas.
A avaliação energética à máquina de impregnar tela, não foi efetuada com o auxilio dos sistemas de gestão implementados, pois só foram ligados aos sistemas os analisadores de energia eletrica, por isso a avaliação foi feita com ensaios experimentais, lendo os valores de consumos diretamente dos contadores.
O ECO VAC é um sistema de otimização que, dependendo da pressão atmosférica local, controla o caudal de exaustão das estufas, contribuindo assim para melhorar o consumo A de gás natural da máquina de impregnar tela (Zell). Foi estudada a influencia deste sistema em três tipos de telas, verificando-se uma diminuição da ordem dos 8% no consumo de gás natural.
The present work was carried out within the scope of the Dissertation / Internship discipline, of the Master of Chemical Engineering, in the Energy and Biorefinery branch of ISEP, in the company Continental - Industria Têxtil do Ave during the period of 8 months. The main objective of this work was the implementation of a data acquisition systems, ESSDAS and PME (Power Monitoring Expert), software’s aimed at the control and management of energy consumption. At the same time, the evaluation of the implementation of the ECO VAC system was carried out, in the natural gas consumptions of the greenhouses of the screen impregnation machine. For the implementation of the management systems, a previous study of its operation was made as well as the optimization of the existent communications to eliminate the faults that occurred. The PME was functional for the electric energy analyzers, with the rest still under study to evaluate the best way to communicate with the server. The MESSDAS, due to the constant occurrence of errors, coming from the parallel communication of the two software’s, was in standby. It is then necessary to determine the correct parameterization so that the measuring equipment can communicate with both management systems without failures. The energy evaluation of the screen impregnation machine was not performed with the id of the implemented management systems, since only the electrical energy analyzers were connected to the systems, so the evaluation was done with experimental tests, reading the consumption values directly from the counters. ECO VAC is an optimization system that, depending on the local atmospheric pressure, controls the exhaust flow rate of the greenhouses, thus contributing to improve the natural gas consumption of the impregnating machine (Zell). The influence of this system was studied in three types of screens, being verified an 8% drop in natural gas consumption.
