A METHOD OF DISTILLING A LIQUID COMPRISING THE STEPS OF CAUSING SAID LIQUID TO FLOW RAPIDLY FROM A SOURCE UPWARDLY THROUGH A CONDUIT INTO A LOW PRESSURE REGION, RELEASING DISSOLVED NON-CONDENSABLE GASES THEREIN, SUBJECTING A PORTION OF SAID LIQUID TO EVAPORATION IN SAID LOW PRESSURE REGION, SEPARATING THE EVAPORATED PORTION, AND CONDENSING AND RECOVERING SAME IN LIQUID FORM, RETURNING THE UNEVAPORATED PORTION OF SAID LIQUID TO SAID SOURCE BY CAUSING THAT UNEVAPORATED PORTION TO FLOW RAPIDLY DOWN TO SAID SOURCE THROUGH A BAROMETRIC LEG, AND PREVENTING PRESSURE BUILDUP WHICH TENDS TO OCCUR THROUGH THE RELEASE OF SAID DISSOLVED NON-CONDENSABLE GASES IN SAID LOW PRESSURE REGION BY CONVEYING THE RELEASED GASES TO THE TOP OF SAID BAROMETRIC LEG AND INJECTING SAID GASES INTO THE DOWNWARDLY FLOWING LIQUID IN SAID LEG WHILE MAINTAINING THE DOWNWARD TO VELOCITY OF THE LIQUID IN SAID LEG AT A VALUE SUFFICIENT TO OVERCOME THE BUOYANCY OF SAID GASES IN SAID LIQUID, WHEREBY SAID GASES BECOME ENTRAINED BY THE RAPIDLY FLOWING LIQUID AND ARE CARRIED ALONG THEREBY TO BECOME COMPRESSED BY THE INCREASING PRESSURE OF THE LIQUID IN SAID STEAM.
