Phase separation barrier distillation apparatus

Claim 1

IN A STILL, A STATIONARY HEAT EXCHANGER AND PHASE SEPARATION BARRIER FORMING AN EVAPORATION CHAMBER ON ONE SIDE AND A CONDENSING CHAMBER ON THE OTHER SIDE, SAID BARRIER PROVIDING ON THE EVAPORATING SIDES THEREOF A PLURALITY OF ANNULAR EVAPORATING SURFACES AND ON THE CONDENSING SIDE THEREOF A PLURALITY OF ANNULAR CONDENSING SURFACES WITH THE EVAPORATING SURFACES ON ONE SIDE OF SAID BARRIER AND IN HEAT TRANSFER RELATIONSHIP WITH THE CONDENSING SURFACES ON THE OPPOSITE SIDE OF THE BARRIER, MEANS FOR CONTINUOUSLY APPLYING DISTILLAND TO EACH OF SAID EVAPORATING SURFACES RADIALLY INWARDLY FROM THE OUTER PERIPHERY THEREOF AT A RATE IN EXCESS OF THAT REQUIRED TO WET SAID EVAPRORATING SURFACES, A ROTARY STRUCTURE OPERABLE TO SPREAD AND FLOW SUCH DISTILLAND RADIALLY OUTWARDLY ON EACH OF SUCH EVAPORATING SURFACES IN A FILM OF SUBSTANTIALLY GREATER THERMAL CONDUCTIVITY THAN CAN BE SECURED BY A FLOW OF SUCH DISTILLAND OF THE SAME THROUGHOUT ON THE SAME SURFACE FLOWING UNDER THE INFLUENCE OF GRAVITY ALONE, MEANS FOR WITHDRAWING FROM SAID EVAPORATING CHAMBER VAPOR EVOLVED FROM SAID FLOWING FILMS OF DISTILLAND, SAID ROTARY STRUCTURE ACTING ON THE RESIDUE FOR IMPELLING THE SAME RADIALLY OUTWARD ON SAID EVAPORATING SURFACES SO AS TO SEPARATE THE RESIDUE FROM THE DISTILLAND AND TO CENTRIFUGALLY DISCHARGE THE RESIDUE FROM SAID EVAPORATING SURFACES, MEANS FOR DIRECTING VAPOR TO BE CONDENSED INTO INTIMATE CONTACT WITH SAID CNDENSING SURFACES SO AS TO CONDENSE SUCH VAPOR THEREON AND TO TRANSFER THE HEAT OF CONDENSATION THEREOF TO SAID FLOWING FILMS ON SAID EVAPORATING SURFACES TO EFFECT THE EVOLUTION OF VAPOR THEREFROM, AND PROVISIONS FOR EFFECTING THE FLOW OF CONDENSATE FROM SAID CONDENSING SURFACES SO AS TO SEPARATE SAID CONDENSATE THEREFROM.
