THE METHOD FOR SEPARATING WATER FROM AN AQUEOUS SOLUTION COMPRISING SUPPLYING AN EXCESS OF LIQUID PROPANE TO A VERTICAL HYDRATE-FORMING ZONE AS FINELY DIVIDED DROPLETS FOR CONTACT WITH AN AQUEOUS SOLUTION IN A HYDRATEFORMING ZONE UNDER CONDITIONS FAVORING HYDRATE FORMATION TO FORM HYDRATE CRYSTALS, PART OF SAID DROPLETES VAPORIZING AND REDUCING THE TEMPERATURE IN THE AQUEOUS SYSTEM IN SAID HYDRATE-FORMING ZONE TO FROM -3* TO +3C., THE VAPORIZATION OF PART OF SAID DROPLETS IMPRESSING AN UPWARD FORCE ON THE SOLUTION AND HYDRATE TO CIRCULATE THE AQUEOUS SYSTEM UPWARD THROUGH SAID HYDRATE-FORMING ZONE, REMOVING A SUBSTANTIAL PORTION OF HYDRATE CRYSTALS IN A SEPARATION ZONE FROM THE REMAINING AQUEOUS SOLUTION, CONTINUOUSLY CIRCULATING SAID AQUEOUS SOLUTION TO A VERTICAL HYDRATE DECOMPOSITION ZONE THAT IS 1/3 TO 1/20 AS LARGE AS THE HYDRATE-FORMING ZONE AND CIRCULATING SAID SOLUTION WITH SUBSTANTIAL VELOCITY DOWN THROUGH SAID DECOMPOSITION ZONE WHILE RAISING THE TEMPERATURE OF THE AQUEOUS SOLUTION CIRCULATING THROUGH SAID DECOMPOSITION ZONE UNDER CONDITIONS FLAVORING HYDRATE DECOMPOSITION AT A TEMPERATURE FROM 0.1 TO 3.0*C. HIGHER THAN THE TEMPERATURE IN SAID HYDRATE-FORMING ZONE BY CONTINUOUSLY ADMITTING FRESH AQUEOUS SOLUTION THEREBY DECOMPOSING HYDRATE CRYSTALS IN SAID DECOMPOSITION ZONE.
