Abstract

Process for recovering organic and/or inorganic products, entrained by water vapor and/or hydrosoluble meltable residues or suspensions containing these products through extraction, characterized in that the extraction is carried out at a temperature below 250ºC feeding the molten residue or the suspension to a column of dripping plates, extracting with steam and/or water condensate, condensing the gas mixture leaving the head of the column and extracting the extracted fusion or suspension that remains together with the descending aqueous phase by the foot of the column and separating.
