Fractionation apparatus

Abstract

Abstract FRACTIONATING APPARATUS COMPRISING TWO SERIES OF CORRUGATED VERTICALLY SPACED SHEETS, EACH OF THE TWO SERIES OF SHEETS EXTENDING HORIZONTALLY, ONE SERIES OF SUCH SHEETS BEING OFFSET FROM THE OTHER SERIES, AND FORMING A PLURALITY OF VERTICAL CHANNELS OR PATHS SO THAT A VAPOR OR VAPOR MIXTURE TO BE SEPARATED AND PASSING UPWARDLY THROUGH SUCH CHANNELS IMPINGES ON THE VERTICAL SURFACES OF THE ALTERNATE OFFSET WALLS OF THE CORRUGATIONS OF THE RESPECTIVE OFFSET SERIES OF CORRUGATED SHEETS, AND IN CONTACT WITH A LIQUID FILM FLOWING DOWNWARDLY ON SUCH VERTICAL SURFACES, PROVIDING AN EFFICIENT FRACTIONATION. IN A PREFERRED EMBODIMENT, A PLURALITY OF SUCH FRACTIONATING UNITS ARE POSITIONED PARALLEL TO EACH OTHER, WITH A PASSAGE OR PASSAGES FOR AN EXTERNAL HEAT TRANSFER FLUID PROVIDED BETWEEN ADJACENT UNITS TO SUPPLY HEAT TO OR TO REMOVE HEAT FROM THE ADJACENT FRACTIONATING UNITS.
