A B S T R A C T PROCESS AND APPARATUS FOR FRACTIONAL DISTILLATION UNDER VACUUM Process for the fractional distillation of a liquid under vacuum comprising heating a liquid to be distilled, forming under vacuum the heated liquid into a first series of thin sheets of free falling liquid to be distilled, and a cooling liquid into a second series of thin sheets of free falling cooling liquid, the thin sheets of the first series alternating with the thin sheets of the second series in close proximity to one another, thereby allowing part of the liquid to be distilled to vaporize and to pass to the thin sheets of cooling liquid to form liquid distillate, and separately recovering the liquid distillate with the cooling liquid and the non-vaporized part of the liquid. The invention further relates to an apparatus for carrying out the above process.
