Abstract
Disclosed is a method for recovering a volatile organic compound (VOC) using pressure swing adsorption carried out with two beds that includes feeding the VOC to the first bed for adsorption and, while the VOC is being adsorbed by the adsorbent material in the first bed, simultaneously extracting the VOC adsorbed by the adsorbent material in the second bed through executing a desorption step by reducing the pressure of the second bed to cause desorption of the VOC in the adsorbent material of the second bed, executing a reflux step by transferring gas to the second bed and removing the transferred gas from the second bed, and executing a repressurization step by increasing pressure of the second bed to a pressure suitable for adsorption of the VOC by the adsorbent material in the second bed.
