Applications of Pinch Technology to Total Sites: A Heavy Chemical Industrial Complex and a Steel Plant

Kazuo Matsuda,     Chiyoda Corporation, Japan

Abstract:

This chapter discusses an energy-saving study based on a Total Site approach, as applied to one of the biggest heavy chemical complexes in Japan and to a large-scale steel plant. The study is based on Pinch Technology using Total Site Profile (TSP) analysis and R-curve analysis. It became apparent that the available Pinch Technology tools and techniques lend themselves very well in the analysis of large-size complexes and steel plants, and it also became clear that there is still a potential for huge energy savings by adopting this approach even though the process systems and plants ...
