The IPSEpro Low Temperature Process Library LTP_Lib allows you to design and analyze: Organic Rankine Cycles (ORC) and Kalina Cycles. The LTP_Lib contains models for both design and off-design analysis.
The Low Temperature Process Library LTP_Lib can be used in combination with the following IPSEpro model libraries:
- Advanced Power Plant Library (APP_Lib)
- Gas Turbine Library (GT_Lib)
