IN A PROCESS FOR THE PREPARATION OF PORTABLE WATER FROM SEA WATER THE STEPS WHICH COMPRISE NUCLEATING SEA WATER, SUBJECTING THE NUCLEATED SEA WATER LIQUOR TO CRYSTALLIZATION BY THE LATENT HEAT OF VAPORATION OF A SUBSTANTIALLY WATER IMMISCRIBE ORGANIC FLUID AT A TEMPERATURE TWEEN MINUS 1.5* C. AND MINUS 10* C. CONDUCTING SUBSTANTIALLY ALL OF THE NUCLEATION AND CRYSTALLIZATION OF THE SEA WATER TO DISCRETE ICE CRYSTALS WHILE THE SEA WATER IS IN A SLURRY OF ICE CRYSTALS AND IN DIRECT HEAT EXCHANGE CONTACT WITH THE EVAPORATING ORGANIC REFRIGERANT, THE ENDOTHERMICITY OF THE EVAPORATING REFRIGERANT BEING SUFFICIENT TO PROPOGATE THE FORMATION OF ICE AND THE GROWTH OF ICE CRYSTALS ON THE CRYSTALS PRESENT AND ALSO SUFFICIENT TO AVOID THE ESTABLISHMENT OF AN EQUILIBRIUM STATE BETWEEN THE ICE AND THE SALINE WATER AND SUFFICIENT TO AVOID THE REVERSION OF THE ICE TO WATER IN THE SUSPENSION AND MAINTAINING THE TEMPERATURE OF THE SEA WATER LIQUID WITHIN A FRACTION OF A DEGREE CENTIGRADE OF THE TEMPERATURE OF THE ICE CRYSTALS, THEREBY RAPIDLY CRYSTALLIZING FRESH WATER CRYSTALS FROM THE SEA WATER.
