Method for producing pure water from sea water and other solutions by flash vaporization and condensation
Abstract
Abstract VARIOUS LIQUID SOLUTIONS WITH OR WITHOUT FINE SUSPENDED PARTICLES MAY BE PURIFIED BY: (A) FLASH EVAPORATION FOR COOLING THE HEATED DILUTE SOLUTION; AFTER (B) A PROCESS WHICH MAY BE PHYSICAL OR CHEMICAL; PRECEDED BY (C) A PREHEATING OF THE LIQUID SOLUTION USING THE HEAT OF CONDENSATION OF THE VAPORS FROM (A). THE PROCESS MAY BE AN EXTRACTION, A PRECIPITATION OF A SOLID AT A HIGH TEMPERATURE, OR A CHEMICAL REACTION; E.G., A SUBMERGED COMBUSTION WHICH MAY SUPPLY THE REQUIRED EXTERNAL HEAT BY OXIDATION WITH ADDED AIR OR OXYGEN OF EITHER A FLUID FUEL OR COMBUSTIBLE ORGANIC MATERIAL DISSOLVED OR SUSPENDED IN THE SOLUTION. PURIFICATION HERE MAY BE BY REMOVING IMPURITIES BY COMBUSTION OR OTHER CHEMICAL ACTION OR BY EXTRACTING OR DISTILLING SOME OF THE WATER FROM THE DILUTE SOLUTION.
