Abstract

A method for collecting volatile organic substances from an off-gas containing moisture and volatile organic substances. The organic substances are removed from the gas containing the organic substances and the moisture by introducing the gas into an adsorbing tower filled with the adsorbents and being in the adsorbing process under a relatively low temperature condition. The gas is discharged outside the system as the gas containing the moisture but from which the organic substances have been removed. The organic substances are desorbed under a relatively high temperature condition in the regenerating process for the regeneration. The moisture is removed from the desorbed gas discharged from the adsorbent regenerating process in a dehumidifying tower filled with the moisture absorbent by the temperature swing method or pressure swing method. The obtained high concentration organic substances containing dry gas is introduced into a liquefier to be cooled and/or pressurized and to be liquefied so that the organic substances are collected. It is therefore possible to collect the organic substances at a high concentration magnification rate without degrading the organic substances and the adsorbents.
