PACKING MATERIAL, AND DISTILLATION SEPARATION METHOD AND DISTILLATION SEPARATION DEVICE BOTH USING SAID PACKING MATERIAL

摘要

Provided are: a packing material which renders a distillation method and a distillation device possible, the method and the device being capable of greatly lowering the reflux ratio and the theoretical number of plates and of lowering the pressure loss of the distillation column to a practical level; and a distillation method and a distillation device both using the packing material. A distillation/separation device 1 is used in an application where light water (H2O) which contains tritium water (HTO or T2O) and which is fed as a raw liquid is separated into tritium water having a higher concentration than the raw liquid and tritium water having a lower concentration than the raw liquid. This distillation/separation device 1 comprises a packed-type multi-stage distillation column 2, a reboiler 3 which heats and vaporizes the liquid gathering in the bottom of the distillation column 2, and a condenser 4 which cools and liquefies the vapor supplied from the top of the distillation column 2. In the distillation column 2 is used a packing material which comprises a packing base having a given shape and, formed on the surface thereof, an adsorption layer constituted of a selectively adsorptive material. The "given shape" means a shape suitable for packing materials.
