Thermodynamics Research Laboratory (TRL) is part of the
Chair of Applied Physical Chemistry and Electrochemistry, Faculty of
Industrial Chemistry, Polytechnic University of Bucharest, Romania.
The main fields of teaching are: Physical Chemistry
(undergraduate level), Equations of state,
Chemical Equilibrium,
Properties of Pure Fluids and Mixtures
(graduate level)
For more than twenty years research work on thermodynamics
has played a dominant role in our activities: measurement of vapor-liquid
equilibria at low pressures, chemical equilibrium - algorithms and computer
programs, equations of state - developments and applications, phase equilibria - algorithms and computer programs, measurement of vapor-liquid
and vapor-liquid-liquid equilibria at high pressures.
The development of equations of state was initiated by the
paper published in 1979:
“Equation
Generale d’Etat de Gaz Adaptable au Proces de Calcul sur Ordinateur”, authors
F. Daneş şi D. Geană, Buletinul IPB, Seria Chimie Metalugie.
Thereafter,
in
a series
of three papers
published
in
1986 in
the
journal
Revista de Chimie
(Bucharest)
–
author
D. Geană – a
new general cubic equation of state was proposed,
called
GEOS. A
long list of papers was published,
since
1987,
together
with co-workers
(specially
with
professor
V. Feroiu).
Since
1990
several Ph.D. thesis were
elaborated
having as
subject new developments and applications of the equations
of state
for pure fluids and mixtures.
More
recently,
on the
basis of a
grant
supported by World Bank and CNCSIS,
experimental research for obtaining
PVT and
VLE data
at high pressures
(5-200 bar)
was started.
Phase
behavior measurements are made in a high-pressure visual cell with variable
volume. In parallel,
computer
and data base programs were developed. Since
2002 these
data base and calculation programs are integrated in
the
software
package
PHEQ
(Phase Equilibria).
The
Windows
interface of PHEQ package,
programed
under
Visual Basic 6,
was
realized
by the
doctorand L. Rus.
The calculation
programs in PHEQ
(re-written
under
Compaq
Visual Fortran
6.6)
and the
data bases are last
versions
of
applications
written and tested between the
years
1986-2003 (authors
D. Geană
and
V. Feroiu).
