<p>PURPOSE: To provide a refining device which eliminates the useless consumption of heating power and the failure in execution of a regeneration stage within time and obviates the degradation in the performance of adsorbents over a long period of time. CONSTITUTION: This refining device is an adsorption column 1 provided with the adsorbents 83 for removing gaseous impurity components in gases in a gas passage 82 formed in an adsorption column body 2. This adsorption column body 2 is composed of a double-shell structure. The internal space of the inside shell 4 of this double-shell structure is formed in the gas passage 82. The part of the inside shell 4 corresponding to the gas inlet 85a of the gas passage 82 is provided with a communicating part 8 making the gas passage 82 communicate with the heat insulating space 9 between both inside and outside shells 3 and 4.</p> |
