Frequently Asked Questions
Prode thermoPhysical Properties Generator
What Prode thermoPhysical Properties generator does ?
PPP provides a thermodynamic framework for calculating thermophysical properties (equilibrium, transport etc.) of pure components and mixtures. Entirely written in C++ language (and part of a set of classes for thermodynamic calc's) it is available in form of DLL for direct access from electronic sheets, user-defined programs etc.
What a DLL is ?
A dynamic-link library (DLL) is a binary file that acts as a shared library of functions that can be used simultaneously by multiple applications. A DLL integrates with spreadsheets (Microsoft EXCEL, LOTUS 1-2-3 etc.) , user defined programs (Visual-Basic, C, C++ etc.) providing additional methods (functions) , extending features etc. Being a compiled code it runs very fast so providing an effective mean to extend application's features.
How do I include this tool in software I am distributing ?
There is a developer licence for this, ask Prode for details.
What data and structures does this framework include ?
Prode Physical Properties generator (base version) includes a compilation with physical properties data and a set of procedures for calculating properties of pure components and mixtures.
How many components can a stream include ?
PPP supports up to 1000 streams, each stream may include from 1 (pure) up to 500 comp's , a stream with a large number of components requires a somewhat large time to solve.
How do I define the thermodynamic models ?
Each stream has its own thermodynamic model for equilibrium, enthalpy, entropy calc's, this permits a great flexibility being the model directly associated to the stream composition.
How do I reference a stream ?
Stream are referenced by a numeric code (a integer) in calling functions, a typical call is :
- setop(stream, double t, double p)
where stream (integer) references the stream.
Properties Generator provides a comprehensive collection of procedures for calculating thermodynamic and transport properties. Prode thermoPhysical Properties generator solves problems as :
- Physical Properties Data
- Heat / Material Balance
- Process Simulation
- Process Control
- Process Optimization
- Equipment's Design
- Separations
- Instrument's Design
- And more ....
How it works
The core of Prode thermoPhysical Properties Generator is a library (Microsoft Windows Dynamic Link Library also called DLL) which links directly with Microsoft Windows applications as :
- Microsoft Excel
- Microsoft Visual Basic
- Microsoft Visual C
- Microsoft Fortran
- Borland Delphi
- Borland C++
- Lotus 1-2-3
- And many more..
Example of PPP integrated with Microsoft Excel application for providing thermophysical properties data directly into Excel's cells
With Prode thermoPhysical Properties generator you will be able to create procedures for solving a quantity of problems and extend your existing applications by including a comprehensive property generator.
The advantages
- easy to use
- it includes a predefined Microsoft Windows procedure for defining streams.
- just one call to calculate VLE, transport properties etc.
- easy to integrate with spreadsheets, custom programs etc.
- Comprehensive, it includes a thermodynamic framework and a pure component data bank.
- Rigorous, robust convergence with simple and non-ideal chemical systems.
- Powerful, support for up to 1000 different streams, simulation of complex problems.
- Flexible, each stream has its own list of components (not a selection from a common list), the thermodynamic model is an attribute of the stream. User can associate ASME Steam Tables with water streams, Soave-Redlich-Kwong with natural gas etc.
Prode Properties
Prode Properties is a Microsoft Windows application included in Prode thermoPhysical Properties Generator. Prode Properties creates graphical and tabular views of properties of pure fluids and mixtures which can be printed or exported into different Microsoft Windows applications via copy and paste clipboard. These graphs and tables can be included in reports, specifications etc.
