Method and apparatus for saline water conversion

Abstract

Abstract SALINE WATER CONTAINING SCALE-FORMING ALKALINE BICARBONATE IS INDIRECTLY HEATED WILE AVOIDING ALKALINE SCALE DUCE TO THE PRESENCE OF RECYCLED CO2. THE HEATED SALINE WATER IS FLASH VAPORIZED AND ALKALINE BICARBONATE THERMALLY DECOMPOSED, FORMING CO2, A PRECIPITATE OF ALKALINE SCALE COMPOUND AND FLASHED SALINE WATER. THE FLASHED VAPOR WITH INCLUDED CO2 IS CONDENSED AND CO2 RELEASED FROM HOT CONDENSATE AS EVOLVED CO2; THE LATTER IS RECYCLED TO THE SALINE WATER, WHILE DISCHARGING EXCESS EVOLVED CO2. PRECIPITATE OF ALKALINE SCALE COMPOUND IS SEPARATED FROM FLASHED SALINE WATER AND EMPLOYED AS NUCLEANT FOR PREICPITATE OF ALKALINE SCALE COMPOUND IS WHEREBY THE THERMAL DECOMPOSITION IS ACCELERATED. THE FALSH VAPORIZATION MAY BE CONDUCTED IN STAGES, A SLIGHT RESIDUAL OF ALKALINE BICARBONATE IN THE FLASHED SALINE WATER BEING THEREBY REDUCED TO AN INDEFINATELY SMALL VALUE. THE FLASHED SALINE WATER IS EVAPORATED IN A MULTISTAGE FLASH EVAAPORATOR; OR THIS COMBINED WITH A SURFACE HEAT EVAPORATOR FORMING CONCENTRATED BRINE AND FRESH WATER AT HIGH YIELD.
