Targeting for energy efficiency and improved energy collaboration between different companies using total site analysis (TSA)
Paper i proceeding, 2010

A chemical cluster located in Stenungsund on the West Coast of Sweden is analyzed to determine the total site level energy efficiency opportunities using the Total Site Analysis (TSA) method. The cluster consists of 5 chemical companies, i.e., AGA Gas AB producing industrial gases, Akzo Nobel Sverige AB producing amines and surfactants, Borealis AB producing ethylene, and PE, INEOS Sverige AB producing PVC and Perstorp Oxo AB producing speciality chemicals. The heart of the cluster is a steam cracker plant run by Borealis, which delivers partly feedstock and fuel to the other plants. The overall heating and cooling demands of the site are ∼ 442 and 953 Mw, respectively. TSA is used to stepwise design a site-wide utility system which improves energy efficiency. Utility savings of ≤ 122 Mw can be achieved, plus a steam excess of 7 Mw. 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. This is an abstract of a paper presented at the 19th International Congress of Chemical and Process Engineering and 7th European Congress of Chemical Engineering (Prague, Czech Republic 8/28/2010-9/1/2010).
