<p><P>PROBLEM TO BE SOLVED: To provide a concentration method of a gas containing a volatile organic matter and to provide a volatile organic gas concentration device. <P>SOLUTION: The volatile gas concentration device 1 supplies the gas containing the volatile organic matter to be treated to a plurality of adsorption columns 5, 7 in order to adsorb the volatile organic matter to an adsorbent, conducts the elimination of the volatile organic matter from the adsorbent in other adsorption column 7 when supplying the gas to be treated to one adsorption column 5 to conduct the adsorption and supplies the eliminated gas which was subjected to the elimination in the other adsorption column to conduct the adsorption together with the gas to be treated, and then repeats the supply of the eliminated gas which was subjected to elimination in the one adsorption column 5 to the other adsorption column 7 together with the gas to be treated to concentrate the volatile organic gas. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
