Closed-loop generating and contacting system
Abstract
Abstract OF PRODUCING THE NECESSARY OXYGEN ENRICHED GAS FOR THE OZONATOR AND MAINTAINING A LOW NITROGEN LEVEL THROUGHOUT THE CLOSED LOOP. BY THIS SYSTEM, WATER CAN BE TREATED WITH OZONE IN A CLOSED LOOP CYCLE, THUS CONSERVING THE HIGH OXYGEN CONTENT GAS USED FOR OZONE GENERATION. THE SYSTEM COMPRISES AS A PRINCIPAL FEATURE A PRESSURE-SWING FRACTIONATOR WHICH REMOVES NITROGEN, CARBON DIOXIDE AND WATER VAPOR FROM A FEED GAS, PRODUCING AN OXYGEN ENRICHED GAS WHICH FLOWS TO AN OZONATOR. ON EXIT FROM THE OZONATOR, THE OXYGEN ENRICHED GAS CONTAIN FROM ABOUT 1 TO 7 PERCENT OZONE. THIS GAS MISTURE IS THEN CONTACTED WITH WATER TO BE TREATED. PURIFIED WATER IS RECOVERED, AND EXCESS GAS MIXTURE, NOW AT LEAST PARTIALLY DEPLETED IN OZONE AND OXYGEN AND ENRICHED IN NITROGEN, FORMS A RECYCLE GAS WHICH IS COMBINED WITH A CHARGE OF AIR AND FLOWED TO PRESSURESWING FRACTIONATOR TO BEING ANOTHER CYCLE. THE PRESSURESWING FRACTIONATOR SERVES THE DUAL SIMULTANEOUS PURPOSE
