Rising fuel prices, the threat of global warming and the start of the 2nd period of the EU Emission Trading System make efficient use of energy more and more important. Industrial clusters have the potential to significantly increase energy efficiency by energy collaboration. In this paper Sweden’s largest chemical cluster is analysed using the Total Site Analysis (TSA) method. The cluster consists of 5 chemical companies producing a variety of products. The overall heating and cooling demands of the site are around 442 MW and 953 MW, respectively. 122 MW of heat is produced from internally generated and purchased fuels and delivered to the processes. TSA is used to stepwise design a site-wide utility system which improves energy efficiency. It is shown that utility savings of up to 122 MW can be achieved, plus a steam excess of 7 MW. The proposed retrofitted utility system involves the introduction of a site-wide hot water circuit, increased recovery of low pressure steam and changes in steam levels in several heat exchangers. Qualitative evaluation of the suggested measures shows that 60 MW of the savings potential can be expected to be achieved with moderate changes to the process utility system.
