Abstract
A semi-batch fractionation of a synthetic mixture of fatty acids ethyl esters was carried out by
means of supercritical carbon dioxide. The feed was composed of five ethyl esters of fatty
acids of different chain length (from C14 to C22), chosen in order to represent a typical
product derived from esterification of sardine oil. C20 and C22 classes were represented by
EPA and DHA, which are the two major ϖ-3 fatty acids. Experimental temperature ranged
from 42 to 60 °C, while pressure ranged from 9 to 16 MPa. The results obtained show that the
process is capable of producing a raffinate rich in EPA and DHA. A modellization of the
process based on the Peng-Robinson equation of state was developed. Two binary parameters
related to interactions between CO2 and ethyl esters were used.
