Conclusions
The phase behaviour of PDLA, trichloromethane, and carbon
dioxide ternary mixture systems were determined from (313.15
to 363.15) K using a variable volume view cell at pressures up to
33.6 MPa. The bubble point or cloud point occurred depending
on the mass fraction of PDLA, the CO2/trichloromethane mass ratio,
and temperature. As the mass fraction of CO2 and PDLA increased,
the cloud point occurred quickly, whereas the cloud point occurred
slowly when the trichloromethane mass ratio increased. The
correlation results were obtained with the hybrid equation of
state using the van der Waals one-fluid mixing rule with three
adjustable binary interaction parameters. The correlation
results indicate an AADP (%) of about 3.18 to 4.37 [AADP (%) =
4.00 (wt 1.0%), 4.37 (wt 2.0%), and 3.18 (wt 3.0%)].
