Volatile organic compounds(VOCs) are a major air pollutants emitted by the laundry facility where organic solvents are used. For the removal of VOCs, the adsorption method using activated carbon has been widely utilized. The activated carbon adsorbing VOCs until the breakthrough point is required the desorption process in order to re-use. The conventional desorption method by using the steam of high temperature has a risk of fire and requires a water separation step. In this study, the low-temperature vacuum system was applied to the activated carbon for controlling VOCs generated by laundry facility After the adsorption/desorption experiments were performed by using actual outlet gas emitted from laundry facility, the absorption capacity of toluene were tested on a lab scale for activated carbon. In addition, the change in the adsorption capacity and physical properties of the adsorbent in the cyclic adsorption and desorption process were confirmed. |
