Evaporative method
Abstract
Abstract THE METHOD OF VAPORATION FEATURING HUMIDIFICATION IS EFFECTED IN A CHAMBER MAINTAINED AT A DOWNWARDLY INCRESING TEMPERATURE GRADIENT. THE LIQUID BEING TREATED AND A VAPOR CARRIER GAS ARE PASSED DOWNWARDLY THROUGH THE CHAMBER WHERE THE CARRIER GAS IS ENRICHED IN VAPOR FROM THE LIQUID. THE ENRICHED CARRIER GAS EXITING FROM THE BOTTOM OF THE CHAMBER IS MOVED UPWARDLY ALONGSIDE THE CHAMBER AND IN HEAT TRANSFER RELATION WITH THE FLUIDS WITHIN THE CHAMBER. HEAT IS APPLIED TO THE BOTTOM PORTIONS OF THE CHAMBER TO ASSURE THE DESIRED TEMPERATURE GRADIENT. CONDENSATION OCCURS ON THE OUTSIDE OF THE CHAMBER. THIS CONDENSATE AND THE CONCENTRATED LIQUID CAN BE RECOVERED. THE HEATED LIQUID CONCENTRATE EXITING THE BOTTOM OF THE CHAMBER MAY BE FURTHER TREATED.
