With hundreds of users and good reputation Prode Properties deserves a closer look, download the free evaluation version and test yourself the features.
When introduced in 1996 it was the first thermodynamic framework designed to provide advanced features as those available in process simulators within common Windows applications as Microsoft Excel, Matlab or custom software, now it is a mature and stable product which has been tested by Prode and other companies in many different applications including extensive (more than 10 years of service) realtime, it provides a stable platform easy to utilize in everyday work but properly designed for industrial use.
Prode Properties permits to calculate the properties of a pure fluid or a mixture, solve two phase (vapor-liquid) three phases (vapor-liquid-liquid) and a limited number of multiphase (vapor-liquid-solid) separations, print phase envelopes , phase diagrams, calculate heating / cooling curves etc. Prode Properties does all this for you easily, rigorously and from your favourite Microsoft Windows software.
Typical applications are :

• Properties of pure fluids and mixtures
• Thermodynamics, physical, thermophysical properties
• Process simulation
• Heat / Material Balance
• Process Control
• Process Optimization
• Equipment's Design
• Separations
• Instrument's Design
• Realtime applications
• petroleum, refining, natural gas, hydrocarbon, chemical, petrochemical, pharmaceutical, air conditioning, energy, mechanical industry

Work with your favourite software

Prode Properties integrates directly (you DO NOT need to run and connect two independent applications) with almost all Microsoft Windows software including:

• Microsoft Excel
• Microsoft C, VB, VBA, NET, FORTRAN, JAVA
• Borland Delphi, C++
• Matlab

In addition to permit the direct complete control of all methods in the library Properties exposes a complete interface which permits to access all informations (as compositions, operating conditions, models, options) for all streams, this simplifies considerably the operation, you can verify yourself how easy working with Properties is!

Example of Prode Properties integrated with Microsoft Excel for calculating a phase envelope (vapor liquid phase diagram) of a natural gas mixture (14 components) including cricondentherm cricondenbar and critical point, the base version adopts a full Newton solver (dense matrix) and with Excel the program takes less than 5 seconds to produce the results (about 400 equilibrium points converged with a tolerance of 1.0E-9 on all specifications), for mixtures with more components or where speed is the most important factor versions which adopt different solvers are available.

Some application examples:

• Properties of pure fluids and mixtures in Excel
• Multiphase equilibria in Excel
• Phase envelope in Excel
• Dew, Bubble point in Excel

The advantages

With Prode Properties you will be able to create procedures for solving a quantity of problems and extend your existing applications by including a comprehensive property generator.

• easy to use
• it includes a tiny dialog based interface to Microsoft Windows or Linux for defining streams, access data etc.
• just one call to calculate VLE, VLLE, SLE etc. phase equilibria, transport properties etc.
• easy to integrate with spreadsheets, custom programs etc.
• Comprehensive, it includes a thermodynamic framework, a pure component data bank, a BIPs data bank
• Rigorous multiphase convergence with non-ideal systems.
• Support for up to 100 different streams, simulation of complex problems.
• Each stream has its own list of components and model, there are no limits on number of phases, (limited) support for multiphase (gas,liquid, solid), the user can select different models per each property (F,H,S,V) and state (gas,liquid,solid).
• easy connection with external applications via OPC, MODBUS library interfaces

Create new applications or extend your existing software

Prode Properties Windows version is provided in form of dynamic link library, a dynamic-link library is a binary file that acts as a shared library of functions that can be used simultaneously by multiple applications. these libraries are compatible with almost all Microsoft Windows applications and being compiled code they run fast. They also integrate tightly with your application, allowing it to run as an autonomous program unit rather than being dependent on external modules of a different application. Prode Properties includes file I/O , graphical interfaces etc. for a total of about 180000 lines of code, all the code (compiled with last version of Microsoft C++ compiler) resides in a library , ppp.dll of about 4 Mbytes , it’s a very compact and efficient code, easy to distribute with your application. .

Compact, stable and easy to use code

The unique structure of Prode Properties, which includes in a single compact file a hundred of classes including graphical interface, File I/O etc., greatly simplifies utilize and distribution. It integrates perfectly as add-in, solving a complex flash operation requires just a call to a single method, additional benefits are stability, flexibility and modularity, when required we can add easily new features on request.
