In 2005, a colleague from Malaysia gave me an odd Christmas gift — a photocopy of an obscure doctoral thesis on industrial energy conservation using heat exchange networks by Charles Hohmann dating back to 1971. This document, with its typewritten text and painstakingly hand-drawn figures, was a treasure of sorts, a lost document in the field of pinch analysis and process integration.
