Desalination process

Abstract

Abstract A PROCESS OF DESALINATING WATER BY FORMING AN EMULSION COMPRISING DROPS OF SALT WATER COATED WITH SURFACTANT MEMBRANES, AND WASHING THE EMULSION TO R4ECOVER PERMEATEDPRODUCT WATER FROM THE SURFACE OF THE DROPS.! APROCESS FOR SEPARATING WATER FROM A SUBSTANCE SOLUBLE THERIN WHICH COMPRISES PASSING AN AQUEOUS SOLUTION OF SAID SUBSTANCE TOGETHER WITH AN OIL ANS ASURFACTANT INTO AN EMULSIFICATION ZONE, EMULSIFYING THE MIXTURE OF SAID AQUEOUS SOLUTION, OIL AND SURFACTANT WHEREBY DROPLETS OF SAID AQUEOUS SOLUTION ARE COATED WITH A WATER IMMISCIBLE MEMBRANE, SAID MEMBRANE BEING MORE PERMEABLE TO EITHER WATER OR THE WATER SOLUBLE SUBSTANCE THAN TO THE OTHER COMPNENT OF THE AQUEOUS SOLUTION, WASHING THE EMULSION WITH AN AQUEOUS SOLVENT PHASE WHEREBY THE MORE PERMEABLE COMPONENT PASSES THROUGH THE MEMBRANE INTO SAID SOLVENT PHASE AND AN AQUEOUS SOLUTION RICH IN THE LESS PERMEABLE COMPONENT REMAINS WITHIN SAID MEMBRANE, SEPARATING THE SOLVENT ROM THE EMULSION, BREAKING THE EMULSION COMPRISING SAID MEMBRANE AND SAID AQUEOUS SOLUTION RICH IN THE LESS PERMEABLE COMPONENT, AND RECOVERING A MIXTURE RICH IN THE MORE PERMEABLE COMPONENT FROM SAID AQUEOUS SOLVENT PHASE.
