Abstract
A process for obtaining free fatty acid and/or free fatty acid ester, including separating a liquid mixture containing the free fatty acid and/or the fatty acid ester by contacting a vapor of the liquid mixture in a column of a distillation apparatus with condensate formed from the vapor running downward. Heat and mass transfer takes place between the vapor and the condensate on column internals. The column has at least 10 theoretical plates and the separation is conducted with a pressure drop between the top and bottom of the column of Δp of ≥3.3 mbars. Appropriately, the liquid mixture, contains polyunsaturated fatty acid, preferably omega-6 or omega-3 fatty acid and/or alkyl monoesters and/or glycerol monoesters. In one embodiment the column has at least 30 theoretical plates and the separation is conducted with a pressure drop Δp between 3.5 mbar and 6 mbar.
