Abstract
The present invention includes two beds of activated alumina or similar material, which can remove moisture during a PSA cycle. One bed is placed in series in each drive air line for the pressure intensifier or boost pump. The beds are sized such that there is sufficient material to adsorb the moisture contained in the volume of gas required to move the drive piston through a complete stroke.
