Pressure Swing Absorbers
Activated carbon enables customized purification of pressurized gases.
Dedicated regeneration systems operate on the principles of pressure differences for hydrogen or nitrogen purification. Some gases are adsorbed better by activated carbon when under high pressure. As one gas passes through the filter, the other is released when the filter swings to low pressure. These systems are called pressure swing adsorption units and are used in many industries where technically clean hydrogen, methane, carbon dioxide (CO2), nitrogen or other gases are needed.
