Filler, distillation separation method and distillation separation apparatus using the filler

摘要

A distillation method and a distillation apparatus capable of realizing a distillation method and a distillation apparatus capable of reducing the reflux ratio and the number of theoretical plates to a practical level, and a pressure loss of the distillation column, a distillation method using the packing material, and A distillation apparatus is provided. The distillation separation apparatus 1 is used for separating light water (H2O) containing tritium water (HTO or T2O) supplied as a stock solution into a tritium water having a higher concentration than the stock solution and a tritium water having a lower concentration than the stock solution. used. The distillation separation apparatus 1 cools the vapor supplied from the packed multistage distillation column 2, the reboiler 3 that heats and vaporizes the stored liquid at the bottom of the distillation column 2, and the top of the distillation column 2. And a condenser 4 to be liquefied. As the packing material for the distillation column 2, a packing material in which an adsorption layer made of a selective adsorptive material is formed on the surface of a packing substrate having a predetermined shape is used. Here, “predetermined shape” means a shape suitable as a filler.
