The PC-SAFT model is a simple engineering-like equation of state. However writing a computer code for the calculation of thermodynamic properties from PC-SAFT will still consume some time. This site provides the essential subroutines required for the computation of thermodynamic properties from the PC-SAFT equation of state. The subroutines are written in standard FORTRAN 77.
We offer the following download:
- The download folder “stand-alone.zip” contains the FORTRAN subroutine “PC-SAFT-PROP.f” for calculation of thermodynamic properties and phase equilibrium calculations for binary mixtures from the PC-SAFT equation of state. The file PC-SAFT-PROP is not a stand-alone program. We use a commercial tool for our phase equilibrium calculations, which we may not distribute freely. However if you have a program that performs such calculations, the download-able file may be applied therein. The self-extracting file that you can download contains the FORTRAN source code and a 'readme'-file. This file gives two examples of how an input for the program may look like. You can download these files now.
Prerequisites for the download option:
- The download of PC-SAFT-PROP is particularly interesting for those, who have a program that performs phase equilibrium calculations with any equation of state and who now want to make use of the new PC-SAFT model. A successful implementation of the PC-SAFT-PROP subroutines presumes, that you have some experience with FORTRAN 77. The subroutines of PC-SAFT-PROP may also serve as a starting point for those, who do not have a program for phase equilibrium calculations. Such a program can best be started, when the program-core is given and only the control units have to be dealt with. For further information on PC-SAFT-PROP see here.
