Pinch technology is the most rigorous, systematic and best documented methodology for process design.1–3 Nearly all optimization projects for heat recovery are conducted with some form of pinch analysis. Pinch technology is particularly useful when designing very complex processes as used in the hydrocarbon processing industry (HPI). These projects are focused on achieving high energy efficiency for individual processes, as well as of the whole complex. Pinch technology provides a “final” methodology. At a time when fewer new processing facilities are being built, some may consider “pinch technology to be obsolete.”4 Proponents of this view hold that recently buil
