Method for distillation of liquids
Abstract
Abstract METHOD FOR DISTILLATION OF MATERIAL INCLUDING LIQUID METALS HAVING AT LEAST ONE U-SHAPED TUBE WITH ONE UPSTREAM END CONNECTED TO THE DEVICE TO WHICH THE PURIFIED METAL IS TO BE DELIVERED. THE MATERIAL TO BE PURIFIED IS DISPOSED IN THE BASE OF THE U WHILE THE UPSTREAM LEG IS SURROUNDED WITH COOLING COILS FOR CONDENSATION, AND THE DOWNSTREAM LEG HAS HEATING COILS AT A PORTION THEREOF FOR VAPORIZATION. THE BOTTOM RESERVOIR PORTION OF THE U IS HEATED. BETWEEN THE RESERVOIR PORTION AND THE UPSTREAM LEG OF THE U WITHIN THE DEVICE IS A CAPILLARY TUBE TO CARRY THE HEATED MATERIAL FROM THE RESERVOIR TO THE HEATED REGION. A SERIES OF THESE TUBES CAN BE CONNECTED TOGETHER IN CONTINUOUS FASHION TO PRODUCE A FRACTIONAL DISTILLATION.
