Saving Study on a Large Steel Plant by Total Site Based Pinch Technology

摘要

We applied the total site approach of ”Site Source Sink Profile (SSSP) analysis”, basedrnon pinch technology, to a large scale steel plant. Despite the very high efficiency of thernindividual processes, there is still a huge energy saving potential by adopting thisrnapproach. We found that the available pinch technology tools and techniques lendrnthemselves very well to the analysis of a steel plant. The heat under 300℃ is notrnutilized in a steel plant and we were able to identify the distribution and the quantity ofrnsuch heat and proposed plans to utilize it for energy saving.
