Análise da eficiência energética em uma indústria têxtil: um estudo de caso relacionando perdas e produtividade

Abstract

This work aimed to analyze the energy efficiency (EE) in a textile company in the state of Paraíba energy losses relating to productivity, therefore we performed a literature search about the concepts of productivity, EE, and losses on the textile sector with emphasis spinning sector. The objective of the research was to analyze the relationship between EE and productivity from the point of view of the losses, with the specific objectives to raise productivity if current industry, identifying energy losses exist, raising the potential for improvement and simulate new level compared to improvements in productivity caused by EE. The research was conducted through a case study of an industry in the textile industry, and an applied research focus using quantitative and qualitative document analysis, structured interviews and direct observation as instruments. Variables of productivity (production, consumption and productivity) and energy efficiency (energy management, motor systems and lighting systems), being raised production data; electricity consumption and calculated productivity. Through research we obtained the following results: With respect to the energy profile were observed: a) The energy has the potential reduction in the order of 2% through improved energy management b) The driving system corresponds to 80% of total consumption of electricity and has a potential reduction of 2% and b) The lighting system corresponds to 5% of total consumption and found a potential improvement of 22.86% c) The remaining 15% are for to other energy uses (compressors, air conditioning, etc..) that are not addressed in this study. On the relationship between productivity and EE was found that the variables have a direct relationship, it was observed that the reduction of electricity losses corresponds to 4.74% of total consumption and the increase of 4.96% in terms of productivity, thereby proved the relationship between EE and productivity, and that this is directly proportional.
