Abstract
Abstract:
The objective of this work is the modeling of equilibrium between phases at high
pressure using the equations of state for various binary-systems.
Calculations were carried out by using 5 cubic equations of state EOS (VDW, RK, RKS,
PR, and PT) combined with 2 mixing ruler MR (VW, P-R).
The value of the saturated vapor pressure was optimized by software MATLAB 2017, in
order to obtain a correct representation of the diagrams: Solubility of the fatty acids and
Triglycerides in supercritical CO2 - Pressure.
The results got in this work agree with the: experimental data of the literature, the EOS
with combination the rule of mixture of VW seems most adequate in this work.
