GAS CLEANER AND GAS CLEANING METHOD Russian patent published in 2014 - IPC B01D53/26 

FIELD: process engineering.

SUBSTANCE: invention may be used in chemical industry. Dried gas (I) is mixed with regeneration gas (II) and fed to gas separator (1) to remove condensed moisture and mechanical impurities. Separated gas (IV) is fed to adsorber 2 with dried gas radial inlet and composite adsorbent 4 arranged between helical-radial heat exchange elements. Atmospheric air (V) is used as a coolant. After moisture breakthrough in gas drying adsorber 2 adsorber 3 is connected while adsorbent recovery is effected in adsorber 2. Air (VIII) heated by catalytic air heater is forced by blower 7 inside heat exchange elements for adsorbent recovery. After heating, portion of dried gas (IX) in amount of 5-10 adsorber volume is fed. Then, purge gas feed is terminated while atmospheric air is forced by gas blower 7 into heat exchange elements.

EFFECT: lower material input, inflammability, gas drying gas input, decreased harmful emissions.
