Introduction |
|
Phase equilibria software has been developed in the
Thermodynamics Research Laboratory of Professor Dan Geană at the Chair of
Applied Physical Chemistry of University “Politehnica” of |
|
In 1995, the calculations programs, rewritten in FORTRAN
77, and running under Windows 95, were coupled with databases. The software
for binary vapor-liquid equilibria calculations, called VLE 95, was used in
the department of Applied Physical Chemistry and in other research groups, by
doctorands and students both as learning and research tool. Special programs
coupled with corresponding data bases were used for calculations of
pure-component properties by equations of state (LVV1 and LVVDT
). Other programs were developed for calculations of ternary systems
and three-phase equilibria (GEOSPH3), as well as for critical lines
calculation of mixtures. |
|
At the end of 2001, a project (called PHEQ – Phase
Equilibria Database and Calculation Programs) was started to develop software
using modern features of the last Windows programs (2000, Me and XP),
databases applications (MS Access, Visual Basics), and Fortran programming
(Compaq Visual Fortran Compilator). |
|
The PHEQ project, is a software to manage databases
for pure component experimental properties, binary VLE experimental data, ternary VLE experimental data, which can be supplied by the user, and the
application programs for correlation and/or prediction of phase behaviour of
pure component, two-component systems and three-component systems. Graphical output is integrated in the software, in
order to provide plots of phase diagrams, and tools to export calculated and
experimental information to other software like Word or Excel. The database
software was programmed by Liviu Rus, at the
Chair of Applied Physical Chemistry. The calculation programs (LVV1DT, GEOSK2, HVID,
GAMMA, UNIFAC and GEOSPH3 ) are revised Windows versions of the DOS programs written by
Dan Geană and Viorel Feroiu for VLE95. |
