PRESSURE SWING ADSORPTION DRYER FOR PNEUMATICALLY DRIVEN PRESSURE INTENSIFIERS

摘要

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 boos t pump. The beds are sized such that there is sufficient material to adsorb th e moisture contained in the volume of gas required to move the drive piston through a complete stroke.
