Resumen

Experiments to determine the number of transfer units (NTU) and height of a transfer unit (HTU) of different random packings such as Raschig rings, Dixon rings, Fenske rings and glass beads in a countercurrent (CC) supercritical fluid extraction (SFE) column of 17.6 mm I.D. and 1.8-m length at 20 MPa and 313 K, with olive oil and CO2, were performed. The extracts were collected by means of two separators, the first one operated at 10 MPa and 313 K and the second at 3 MPa and 273 K. The performance of SFE was studied by analyzing the content of vitamin E and sterols in the raffinate and in the collected extracts by HPLC equipped with a photodiode array detector. The value of HTU and the NTU were evaluated for each random packing at solvent to feed ratios from 23.14 to 41.65 kg CO2/kg oil. Fenske rings showed the best results in terms of efficiency and performance of the CC system for the SFE of olive oil.
