摘要：<p>PURPOSE:To enable considerable reduction in the heating part of an adsorption column by heating only the inlet part of the gas to be treated in an adsorbent material layer with a heater and exhausting and recovering the desorbed gas from the direction opposite from the direction in the adsorption operation. CONSTITUTION:Regeneration of an adsorbent layer 3 wherein corrosive gas such as HF or UF6 is adsorbed is accomplished by closing valves B1, B3, and starting an exhasting device 7 then heating the inlet part for the gas to be treated in the layer 3 in an adsorption colum 2 to the desorbing temp. range of the adsorbed gas, i.e. >=200 deg.C by using a heater 4. Valves B2, B4 are then opened to supply air from the outlet part for the gas to be treated in the column 2 in the flow direction of the desorbed gas shown by a code 9 so that the desorbed gas is discharged from the inlet part for the gas to be treated of the column 2 and is recovered in a device 6 for recovering the desorbed gas. The recovered gas is evacuated from the device 7.</p>
