Abstract
Abstract THE PRESENT INVENTION RELATES TO METHODS AND SYSTEMS FOR CONTINUOUSLY RECONCENTRATING A SOLUTION OF LIQUID ABSORBENT AND SOLUTE. THE COLUTION TO BE RECONCENTRATED IS INTRODUCED INTO A RECONCENTRATOR HAVING A FUEL BURNER AND FIRE BOX ASSEMBLY DISPOSED THEREIN. A STREAM OF FUEL IS BURNED IN THE BURNER AND FIRE BOX ASSEMBLY THEREBY VAPORIZING THE SOLUTE AND RECONCENTRATING THE LIQUID ABSORBENT. PRIOR TO BURNING, THE STREAM OF FUEL IS PASSED THROUGH A JET EJECTOR. THE SUCTION CHAMBER OF THE JET EJECTOR IS CONNECTED TO THE RECONCENTRATOR SO THAT VAPORIZED SOLUTE IS EVACUATED THEREFROM AND THE PRESSURE THEREIN IS REDUCES.
