Vapor compression distillation system

A distillation system comprising:

• a stripper solumn arranged for the introduction of hot feed liquid into the top and vapor into the bottom, said stripper column having an outlet means at its top for eszcape of exiting vapors and an inlet means at its bottom for the entrance of said vapor;
• a reboiler unit positioned below said stripper column and coupled to said inlet means, said reboiler containing liquid and comprising heating means for producing vapor from said liquid;
• a rectifier column for enriching the vapor which exited the stripper column, the bottom of said rectifier column comprising inlet means for said vapor, and the top of said rectifier column comprising means for outlet of the enriched vapor and inlet of liquid reflux;
• a first line for transmitting vapor from the top of the stripper column to the bottom of the rectifier column;
• a vapor pump for increasing the pressure and temperature on said enriched vapor;
• a second line for transmitting said enriched vapor from the top of said rectifier column to said vapor pump;
• a third line for transmitting said hot compressed enriched vapor from said vapor pump to the top of said reboiler and continuing through said reboiler to an exit at the bottom of said reboiler;
• a distillate heat exchanger for cooling the distillate liquid and heating the incoming feed liquid;
• a fourth line in continuation of said third line connecting the bottom of said reboiler with said distillte heat exchanger in counterflow direction to said incoming liquid feed;
• a float chamber to amintain the desired backpressure on the system back to said vapor pump, to divert the proper amount of distillate to storage, and to provide a pressureized source of relux liquid;
• a fifth line for conduting liquid distillate from said distillate heat exchanger to said float chamber;
• a sixth line for carrying a portion of said distillate as reflux from said float chamber to the top os adi rectifier column;
• a bottoms heat exchanger;
• a seventh line for bringing incoming cool feed liquid into the system through said distillate heat exchanger continuing through said bottoms heat exchanger and connecting to the top of said stripper column for warming feed liquid in said distillate heat echanger, further heating said feed liquid in said bottoms heat exchange, and introducing said hot liquid feed into the top of said stripper column;
• an eighth line for carrying hot spent liquid bottoms from said reboiler to said bottoms heat exchanger, continuing through said bottom sheat exchanger in counterflow direction to said seventh liquid line, and continuing through a bottoms outlet pump;
• and
• a ninth line connected to said float chamber for conducting distillate product from said float chamber to product storage;
• whereby available heat from said bottoms liquid and said distillate vapor is withdrawn and reused by the distillation unti before said bottoms liquid and said distillate product exit the system to storage.
