At fixed pressure of 34.5 MPa increasing the extraction temperature
followed the same previous trend at 27.6 MPa pressure. The
extraction yields at operating temperature of 40 C and 50 C were
33.5%, 32.8% g oil respectively. The highest extraction yield was
36.9% g oil at a temperature of 60 C as shown in Fig. 2c. The reduction
in the extraction yield at a temperature of 50 C could be related
to the solvating power of the supercritical fluid, as it is
more dependent on temperature and pressure.
