Title:
Volatile organic compound recovery subsystem
Document Type and Number:
Japanese Patent JP5990722
Kind Code:
B2
Abstract:
An untreated gas which contains a volatile organic compound is supplied to an adsorption tower (1), whereby the volatile organic compound is adsorbed onto the adsorbent. After completion of the adsorption, a volatile organic compound which has higher adsorbability than that of the volatile organic compound adsorbed onto the adsorbent is supplied to the adsorption tower (1) through a desorption gas supply valve (4). The volatile organic compound which has low-adsorbability and has been adsorbed onto the adsorbent is then desorbed therefrom due to competitive adsorption with the high-adsorbability volatile organic compound fed later, and the high-adsorbability volatile organic compound itself is adsorbed onto the adsorbent instead. As a result, the volatile organic compound which has been adsorbed is discharged from the adsorption tower (1) and recovered.
