Supercritical Fluid Extraction- Process Simulation and Design

Show full item recordAbstract
Supercritical fluid extraction (SFE) currently finds application in
the food and petroleum industries. Research is aimed at using
the unique properties of supercritical fluids to perform
industrially significant separations. One major problem in
application of SFE to separations is the lack of simulation/design
experience for these processes. The work of the Separations
Research Program at the University of Texas involves both the
development of fundamental models and design procedures so
that industry can better design separations processes.
This paper will briefly discuss the previous experimental work
done in the area of SFE, the experimental system and equipment
currently being used at the University of Texas to study SFE and
our first attempt to simulate this process using our own
experimental data. In our case study, we will use data taken
from one experimental run to simulate process flows, energy
requirements and process conditions when separating isopropyl
alcohol (IPA) from water employing supercritical carbon dioxide
as the solvent. The SFE process is modeled using a
commercially available computer process simulation program
provided by Simulation Sciences, Inc. As might be expected,
very little is known about the liquid-liquid and vapor-liquid
equilibrium for multicomponent systems at high and supercritical
pressures where there is a high degree of liquid phase non-ideality.
Experimental data was used to specify separations
where this data is currently unavailable. In addition, a standard
data generation package was utilized from the process simulator
to calculate this data where applicable conditions were met.
