PINCHLENI - Freeware Program for Pinch Analyses

PINCHLENI is a program for the energetic analysis of industrial processes. The Pinch Method evaluates the minimal heat input necessary for each process and how much heat can theoretically be internally recovered. PINCHLENI works according to the Pinch Method of Linnhoff-March.

This software enables

• the drawing of composite curves and the grand composite curve
• the determination of the specific optimal pinch point, as found through economic or exergetic criteria
• the construction of heat transfer networks
• the integration of heat pumps and combined heat and power units
• the compilation of an exergetic balance sheet and the recording of exergetic factors
• the analysis of “batch” processes, the drawing of composite curves for different time periods and the evaluation of storage.

The Laboratoire d'Energétique Industrielle de l'Ecole Polytechnique Fédérale de Lausanne, Switzerland (Industrial Energy Systems Laboratory), owns the rights for the PINCHLENI program.

The PINCHLENI Program was developed by Michel TOURN, Ivan VECERINA, Pierre KRUMMENACHER and Frédéric STAINE from the Laboratoire d'Energétique Industrielle (Director Professeur Daniel FAVRAT). The PC Windows version was financed by the Swiss Federal Office of Energy.
