Abstract [en]

There are strong associations between standard of living, and energy and material use in the society. In fact, a higher "consumption" of energy and materials is often regarded as synonymous with human wellbeing. To make this fit in with the ideas of the sustainable society, it is important to assure that the industrial systems are designed in an energy and material efficient way, and to enhance the understanding of which barriers or bottlenecks we must do something about to become even more efficient in the future.The MIND method (Method for analysis of INDustrial energy systems) has been developed to model different types of industrial energy systems. The method can also be used to model and analyse other aspects of industrial systems, not only the energy issues. The system to be analysed with the method is represented as a network of process nodes, and nodes representing auxiliary units, connected by energy and material flows. The MIND method is based on Mixed Integer Linear Programming (MILP), meaning that relationships in the system are normally described as linear functions. The potential of the MIND method is that it enables a simultaneous representation of the total industrial system, a production site, or several aggregated production sites. By focusing on the larger system, the centre of attention can be drawn from optimisation of the production processes one by one, as in traditional process development. Instead, it is possible to focus the analysis on the flexibility and the most favourable interactions between different parts of the system.Examples on industrial systems for material production, which have been modelled using the MIND method, are pulp and paper production and steelmaking. Both types of material production involve several processing steps with a high degree of heat and material management. Another likeness is that both materials can be produced from recycled materials and that the recycling rates from the society are among the highest, compared to other materials. The MIND method has shown grand potentials for analysis of these productions system, and also for other systems, such as food manufacturing and chemical industries. It can also be used for analysis of possible synergies between neighbouring industries, or between an industry and the nearby society. In this paper the methodology will be described and references will be made to projects where MIND has been used in pulp and paper production and steelmaking.
