METHOD OF GAS TREATING Russian patent published in 2009 - IPC B01D53/02 

FIELD: chemistry.

SUBSTANCE: invention can be used for absorption processes in gas (vapour) - adsorbent system. Gas flow is supplied for treating through connecting branch 5 to the device bottom through the supply net, then delivered through external 2 and internal 3 perforated cylinders with adsorbent 4 in-between. Treated gas flow is removed from adsorber through connecting branch 6. Adsorbent 4 is charged through the fill port in the lid, while used adsorbent is removed the unloading gate. Desorption is enabled with water vapour supplied through connecting branch 6 to bubbler flask with perforated toroidal surface to provide more uniform desorption from any height of perforated cylinders 2 and 3.

EFFECT: higher purification efficiency of gas flow from end component ensured by higher contact area of adsorbent and end component.
