ABSTRACT:
A thermally insulated adsorber (1) intended for treating a gas by passing the gas through a bed (15) of an active material, of the type including a cylindrical shell (5) provided with thermal insulation (21) including a wall (25), which is, in particular, parallel to the shell (5) and which, together with the shell, defines a gas-filled cavity (27), the wall (25) and consequently the gas-filled cavity (27) being placed inside the shell (5), between the latter and a bed (15) of an active material arranged inside the shell (5). The gas-filled cavity (27) communicates with a part of the adsorber (1) which includes the gas that is to be treated and/or with a part of the adsorber which includes the gas that has been treated. The adsorber furthermore includes elements (43) for blocking any gas flow through the gas-filled cavity in order to separate the gas that is to be treated from the gas that has been treated. The adsorber may be used to purify the air sent to air distillation plants.
