ABSTRACT OF THE DISCLOSURE: A solution of crude oil in a solvent is successively contacted with at least two ultrafilters arranged in series and a part of the solvent, solution or filtrate which passed through the ultrafilters is fed into at least one connecting part between the ultrafilters to divide the solution into a filtrate from which phospholipids have been removed and a concentrated phospholipid solution. Degummed oil is obtained from the filtrate and lecithin is obtained from the concentrated solution. The concentrated phospholipid solution is added to an oil meal and used as a fertilizer or feed after removing the solvent.
