Abstract:
Organic Rankine Cycles (ORCs) are often integrated in more complex systems such as geothermal plants, biomass combustion and gasification plants, solar power plants or industrial processes. To optimize the performance of the resulting system, accurate models of the thermodynamic system are of great value. This paper describes the process modeling system IPSEpro and its application to ORCs. With IPSEpro, process models are created from individual components. The user can set up the process scheme graphically by arranging components appropriately and entering the required data in the flowsheet. IPSEpro is a open framework: Components and physical property calculations are not coded into the system. All application specific information is contained in model libraries. A model library for modeling ORC processes is available. The user can combine the ORC library with other existing libraries, like libraries for power processes, for solar power or for biomass gasification. Additionally the user can modify libraries and create new ones using a Model Development Kit (MDK). The paper illustrates the capabilities of the ORC library and presents results obtained. Once a process model exists, its usage is not limited to normal performance calculations. With additional modules, the model can be used for parameter optimization as well as for the validation of measured data. The paper show examples for this usage.
