AirScience - Activated Carbon Process System

The system consists of a minimum of two towers, each having a bed of activated carbon. The gas travels through the carbon bed from bottom to top. Pressure drop through the bed and outlet concentrations are monitored to alert to a change in performance signaling the need to replace the carbon. To replace the carbon, the tower must be put off-stream, the full flow passing through the remaining tower(s) during the emptying and refilling operation. Once one tower has been refilled the other tower(s) must also have their carbon bed replaced, so that all towers have carbon with the approximate same loading.
