The extraction conditions were 80C and 55.2 MPa with a flow rate of 13.6 g CO2/ min.
The receiver vessel (2 L) was 40C and 13.8 MPa. Because the extracted sage still had a strong after a solvent:feed(g:g) ratio of 33:1, the material was re-extracted a second time using SCCO2 without recycling.
The 2nd SC-CO2 extraction was performed using a unit as described previously by Kenar others (2014)without of the automated depressurization regulator
