Abstract: The invention relates to a vaporization and condensation process for the fractionation of mixtures by continuously heating, in a circulation circuit, a clean heat transfer gas which is subsequently injected into a mixture to be fractionated (16), of which at least one liquid fraction, which has separated off by vaporization, is condensed and collected while the heat transfer gas returns to the circulation circuit.

Abstract: The invention, which is useful in the chemical industry, relates to an automatic and continuous vaporization and condensation process for the fractionation of mixtures by continuously heating, in a circulation circuit, a clean heat transfer gas which is subsequently injected into a mixture to be fractionated (16), of which at least one liquid fraction, which has separated off by vaporization, is condensed and collected while the heat transfer gas returns to the circulation circuit.The process is preferentially applied to the recovery of solvents from paint, ink and varnish residues.
