ABSTRACT:
Process for separating solid substances from liquid mixtures of substances, wherein the liquid substances contained in the mixture are separated from the solid substances by countercurrent extraction with a solvent which, during the extraction process, is in a liquid or supercritical state and which, under standard conditions, is gaseous. The solvent is fed to a cylindrical extraction chamber at the lowest point of the extraction chamber. The solvent leaves the nozzles with a Reynold's number of 40,000 and flows upward in the extraction chamber with a Reynold's number of 2,700 to 8,000.
