Adsorption box for single distillation column within the insulated enclosure

摘要

An apparatus for substantially dehumidifying an insulating annular space (108) is provided. This apparatus includes an insulated surrounding envelope (106), an inner cylindrical device (107) and a truncated annular cylinder (100) comprising at least two porous zones. This apparatus positions the truncated annular cylinder (100) within the insulated annular space (108) that is formed by the inner cylindrical device (107) positioned within the insulating surrounding envelope (106). This truncated annular cylinder (100) holds adsorbent.
