Pinch Analysis for the Application in Steel Plants

By Nitin Gupta & T. K. Pal, TCE

The term ‘Pinch Technology’ is a new set of thermodynamically based methods that guarantee the design of heat exchanging networks with minimum energy levels. The equations are primarily based on the First Law and the direction of heat flow is determined by the Second Law of Thermodynamics. This method is very useful for the large and complex industrial facilities and identifies the best energy saving opportunities. Pinch analysis is used in complex processes with extensive exchange of thermal energy. This article outlines the process of Pinch Analysis and study the applicability of pinch analysis in steel plants along with its advantages.
