Sammanfattning: Nymölla Mill is a papermill in the paper division of Stora Enso. Due to its size, the company is forced by law to make energy mappings every fourth year, in order to ensure that that the company is running its business in a sustainable way. When performing an energy mapping, one is supposed to make deeper analyses of the more energy demanding functions at the company as well as a more general mapping of the entire business. The vacuum system in one of the paper machines (paper machine 1) at the mill, is a major energy consumer and is therefore required by law to be analyzed more deeply. This analysis will constitute the main focus of this bachelor thesis, which is made by two students at Jönköping’s School of Engineering, with a total of 30 credits (15 credits per student). The purpose of this thesis is to assist Nymölla Mill in their work with the energy mapping, by making an efficiency analysis of the vacuum system in paper machine 1. The hope is that this thesis will contribute with improvement suggestions, which will make the whole business more efficient and sustainable in an energy perspective. To support this purpose two research questions was formulated, where the first one focuses on the energy losses in the vacuum system and the other on the possible improvements. In order to get the necessary background knowledge, a literature study was made where the law entitled “Lagen om energikartläggning i stora företag” stood in the center. Available energy data has been analyzed and processed in order to form the basis of the energy mapping. In the aim of getting a nuanced picture of the focal point, own observations have been performed alongside with interviews of people who has different perspectives of the vacuum system. The research questions were investigated through analyzing the result of the findings alongside with the literature in the theoretical background. The primary literature focus was on lean, since it was requested by the company itself. The thesis finally resulted in that energy losses were identified and that suggested actions were brought up and discussed.
