Energy saving study on a large steel plant by total site based pinch technology

The total site approach using a "Total Site Profile (TSP) analysis” (based on pinch technology) was applied to a large scale steel plant. And it was confirmed, despite the very high efficiency of the individual process systems of the plant, that there would be a huge energy saving potential by adopting this approach. It became apparent that the available pinch technology tools and techniques lend themselves very well to the analysis of a steel plant. The heat (thermal energy) under 300 °C has previously not been well utilized in steel plants. But TSP analysis was able to identify the distribution and the quantity of such heat, from which energy saving plans could be developed.
