Abstract
An improved method and apparatus for regenerating desiccant in an adsorption dryer is disclosed. The method utilizes a two-phase regeneration, the first phase using the heat from the compressed gas supply to desorb a portion of the moisture from a regenerating desiccant chamber, with the second phase utilizing low pressure, dry product gas. The heat of compression/pressure swing combination offers reduced regeneration energy requirements with improved dewpoint performance.
