Title:
APPARATUS FOR TREATING ORGANIC-CONTAINING GAS AND METHOD OF TREATING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/023659
Kind Code:
A1
Abstract:
An apparatus for treating an organic-containing gas. A gas containing a hydrophilic
organic substance is recovered with the apparatus, and the organic substance
can be greatly reduced in the content of (dissolved) water to such a degree that
even when it is reused in a printing ink, ink running is less apt to occur. Despite
this, a large amount of the organic-containing gas having a low concentration
is effectively adsorbed and then desorbed to efficiently recover the organic
substance. The apparatus can eliminate the risk of explosion without fail.
Also provided is a method of treating the gas. The apparatus for organic-containing-gas
treatment comprises: a dehumidifying mechanism (2) in which water contained
in an organic-containing gas to be treated is removed; an activated-carbon adsorption
device (4) packed with honeycomb activated carbon for adsorptively removing
the organic substance in the dehumidified gas; heated-gas supply devices (6,
7, and 12) with which a heated inert gas is sent in order to separate the organic
substance adsorbed with the activated-carbon adsorption device (4) from the
activated carbon; cooling devices (13 and 14) in which the organic substance
separated with the heated inert gas is cooled to 0 degree or lower to dehydrate
it; and a recovery device (15) in which the dehydrated organic substance is recovered.
