As can be seen in Fig. 4(a) the loading of squalene in scCO2
decreases with increasing scCO2 flow rate. This indicates that
scCO2 is not saturated with squalene at the outlet of the extraction
vessel. Therefore, at these conditions the extraction process is controlled
by the dissolution rate of squalene in scCO2. Thus, lower
residence times of scCO2 in the extraction vessel result in less
squalene dissolved. On the other way, the loading of squalene in
scCO2 increases with increasing pressure, as can be observed from
Fig. 4(b). This was to be expected since the scCO2 density increases
with pressure.
