Energy efficiency optimisation by Industrial process and municipality integration B Kjellström, G Keikkala Division of Energy Engineering The mining industry, including ore extraction, mineral processing and process metallurgy have a high energy consumption. The energy is used for the product as latent heat, for re-circulation in the process or becomes waist energy that can not be used in the process. These industries are located close to the mineral deposits with an adjacent town where the employees of the industry are living. Many of these towns are heated by district heating. The onshore industry in Murmansk Oblast and adjacent areas are dominated by these kind of industries. The cities have district heating. There are almost no energy co- operation between the industry and the cities. This study aim to optimise the energy system by integration of the industrial process and the municipality. The power plant Lulekraft AB and Luleå Energi AB energy integrated with the local steel company SSAB and the town of Luleå In some cities in Sweden there are a energy co-operations. The experiences of these co-operations is a part of this study. One part of the study aims to show on possibilities to use more of the waist energy in the community that not are needed for heating for example needs for cooling of buildings, offices, computers and processes. The research is funded by the Swedish National Energy Administration. Cities in Murmansk Oblast with high energy consumption industries
