As a device of eliminating organic gases
and odors by absorbing and sucking in organic gases and odors
with mechanical and chemical methods, activated carbon tower
eliminates gases with its strong adsorption power?by free
bonding of atoms on the surface of solids composed of molecular
layers and chemical bonding of only gases.
A theory of harmful gas being attached on the surface of adsorbent?is
used on this device, and fatty acid class, mercaptan class,
phenol class, hydrocarbon class(aliphatic and aromatic), organochlorine
compound, alcohol class(except methanol), ketone class, aldehyde
class(except formaldehyde) and ester class can be removed
effectively with activated charcoal.
Hydrogen sulfide, sulfurous acid gas, chlorine, formaldehyde
and amine class can be removed somewhat, and ammonia, methanol,
methane and ethane can’t be removed practically.
Activated Carbon Tower is widely used for removing low-density
mixed offensive odors. For examples, this has been supplied
in many fields such as offensive odors generated from buildings,
hospitals and food processing procedures, excretions, sewages
and refuse disposal and chemical production.
Advantages of activated Carbon Tower are its low installation
cost and its operating expense is only composed of electricity
cost for ventilation and replacement of activated charcoal.
