This unit includes two separate tanks for the solvent and for the phase having to be refined, that are sent to the extraction column by two metering pumps; the column is provided with top and bottom phase separators and with two other tanks for collecting the refined and extracted products. This unit is available in two versions:
• with “rotating-disc” extraction column
• with “packed” extraction column
