Separation of entrained liquid droplets from vapors

Claim 1

A METHOD FOR FORMING A CONTINUOUS WATER VAPOR SUPPLY SUBSTANTIALLY DEVOID OF WATER DROPLETS AND CONDENSIBLE TO PURIFIED WATER, WHICH METHOD COMPRISES CHARGING IMPURE FEED WATER THROUGH A PREHEATING ZONE AND A DEAERATING ZONE TO A VAPORIZING ZONE, HEATING THE WATER IN SAID VAPORIZING ZONE TO VAPORIZATION TEMPERATURE, DIRECTING A MINOR PORTION OF THE VAPORS RISING FROM THE VAPORIZING ZONE TO THE DEAERATING ZONE FOR DEAERATION OF THE FEED PASSING THERETHROUGH, DIRECTING A MAJOR PROPORTION OF THE VAPORS RISING FROM THE VAPORIZING ZONE THROUGH A FIRST DEMISTER ZONE AND INTO CONTACT WITH THE DEMISTER SURFACE WHILE WETTING THE DEMISTER SURFACE WITH WATER AT APPROXIMATELY THE SAME TEMPERATURE AS THE RISING VAPORS, WHEREBY ENTRAINED WATER DROPLETS ARE COALESCED AND REMOVED FROM THE RISING VAPORS, THEREAFTER DIRECTING THE RISING VAPORS THROUGH A SECOND DEMISTER ZONE FOR FURTHER SEPARATION OF ENTRAINED DROPETS, DIVERTING THE WATER VAPOR IN A BUBBLE CAP ZONE INTO CONTACT WITH A BODY OF WATER WHILE MAINTAINING THE BODY OF WATER AT APPROXIMATELY THE TEMPERATURE OF THE RISING VAPORS, PASSING THE RISING VAPORS FROM THE BUBBLE CAP ZONE THROUGH A WATER SPRAY DIRECTED ON SAID BUBBLE CAP ZONE AND THENCE THROUGH A THIRD DEMISTER ZONE FOR FURTHER SEPARATION OF ENTRAINED WATER DROPLETS, RECOVERING A MAJOR PORTION OF THE RISING VAPORS FROM THE THIRD DEMISTER ZONE AS WATER VAPORS IN THE SUBSTANTIAL ABSENCE OF ENTRAINED WATER DROPLETS, DIRECTING A MINOR PORTION OF VAPOR FROM THE THIRD DEMISTER ZONE TO SAID FEED PREHEAT ZONE IN HEAT EXCHANGE WITH FEED PASSING THERETHROUGH WHEREBY THE FEED IS PREHATED AND THE VAPORS ARE CONDENSED, RETURNING THE CONDENSED VAPORS FROM THE PREHEAT ZONE AS REFLUX TO SAID SPRAYING STEP, COLLECTING WATER FROM SAID SPRAYING SETP FOR MAINTAINING SAID BODY OF WATER, COLLECTING WATER FROM SAID FIRST DEMISTER ZONE, RECYCLING WATER COLLECTED FROM SAID FIRST DEMISTER ZONE TO THE WETTED SURFACE OF SAID FIRST DEMISTER ZONE AND RECYCLING WATER FROM SAID BODY OF WATER TO SAID SPRAYING STEP.
