Energy optimization of industrial sites • Data extractionandanalysis • HeatExchangerNetwork (HEN) optimization • HEN synthesissoftware„TVTHENS“ forindustrial-scaleproblems* • Newprocesstechnologies • Absorptionchillers/heatpumpssimulationwith „TRNSYS“ • Renewableenergysystems • Geothermal/solar thermal systemssimulationwith „TRNSYS“ [*] A. Modarresi, A. Miltner, A. Friedl, M. Wiesinger, BESTENS AUSGENUTZT, Chemie Technik, 04 (2011), pp. 64-66
Energy optimization of industrial sites • Heatexchangernetworkoptimization • Pinchanalysis • Grand and Composite curves • Exergyblock diagram • Maximum heatintegrationandminimum Utilities demand • Targeting • MinimizationoftheUtilities demand • Heatloaddistribution • Minimizationofthenumberofheat exchangers • HEN Optimization • Simultaneousminimizationofthe Utilities demandandnumberofheatexchangersas well asminimizationofoverallheatexchangearea • Retrofit TVTHENS* More than 6000 linesofcode in Mathematica [*] A.
