Furthermore, itis considered thatthe supercritical solvent flows
axially through a cylindrical extraction bed, the solvent is solutefree
at the bed inlet and particle size distribution is homogeneous
throughout the extraction cell.
The solid particle density (s) is 1046 kg/m3, bed porosity ()
was determined on the basis of the corresponding apparent density
(411.8 kg/m3) and resulted = 0.6, and CO2 density () at
30 MPa and 343K was determined from thermodynamic tables
( = 788.6 kg/m3) [34].
