Abstract
A vapor recovery method, system, and apparatus for extending the replacement period of the activated carbon or other adsorbent material used in a vapor recovery unit by alternating each of the one or more adsorption vessels used in the vapor recovery unit between a bottom-up adsorption mode, in which the inlet vapor stream flows upwardly through the adsorbent material, and a top-down adsorption mode in which the inlet vapor stream flows downwardly through the adsorbent material.
