When introduced in 1993 Prode Properties was the first
c++ thermodynamic library designed to provide advanced features as those
available in process simulators within common applications. Prode Properties has been verified by Prode and many other companies for more than 25 years of service and now, the different versions available for Windows, Linux and Android can provide a stable platform for both everyday work and industrial applications. Prode Properties represents the best solution when a well tested, compact and easy to use library is required.

Main features:

- Versions available for Windows, Linux, Android and client / server applications
- C++ 17 fast and stable code with full support for multithreading, no limits on number of threads in multicore systems
- Direct integration with tools as Excel, Python, OpenOffice, LibreOffice, Matlab, Mathcad and many others
- Thermodynamic properties, physical, thermophysical properties of pure fluids and mixtures
- Complex, multiphase separations
- Distillation columns (steady state and batch)
- Phase diagrams, hydrate formation etc.
- Areas of application: petroleum, refining, natural gas, hydrocarbon, chemical, petrochemical, pharmaceutical, air conditioning, energy, mechanical industries

- Phase envelopes / diagrams
- Compare phase envelopes / diagrams with different models
- Hydrate formation

The distribution files include several applications examples for Excel, OpenOffice, Python and other tools

With Prode Properties you obtain the calculated results directly in the cells of Excel, OpenOffice, Libreoffice etc. (no need to transfer data with complex procedures)

The editor in Prode Properties allows to define compositions, inspect databases and solve unit operations...
