Effect of Temperature, Pressure, and Air Flow Rate on VOCs Desorption for Gasoline Vapor Recovery Lee, Song-Woo; Na, Young-Soo; Kam, Sang-Kyu; Lee, Min-Gyu;
Desorption characteristics of VOCs were investigated for the effective recovery of gasoline vapor. The adsorption capacity and desorption capacity were excellent at relatively low temperatures. The differences in the desorption capacity were not large in the condition; desorption temperature , desorption pressure 760 mmHg, inlet air flow rate 0.5 L/min, but were relatively great in the condition; desorption temperature , desorption pressure 60 mmHg, inlet air flow rate 1.0 L/min. The desorption ability of pentane was increased to about 81.4%, and the desorption ability of hexane was increased to about 102%, also the desorption ability of toluene was increased to about 156.7% by changes of temperature, pressure, inlet air flow rate in the experimental conditions. The optimum desorption condition for the effective recovery of VOCs was in the conditions; desorption temperature , desorption pressure 60 mmHg, inlet air flow rate 1.0 L/min.
