The adsorption bed is contained in a stainless steel column with six thermoresistances mounted at regular intervals on the column’s length to measure the temperature profile of the adsorbent. The flow of each gas is measured by a mass flow meter and regulated by a pneumatic valve controlled by a PID controller. The operating pressure is measured by a pressure transmitter and regulated by a pneumatic valve controlled by a PID controller. The adsorption and desorption/regeneration process are monitored using the temperature sensors and an infra red detector to measure the composition of outlet gas. Feed to the column is supplied by two cylinders (not supplied), one of pure helium (He), and the other of pure carbon dioxide (CO2).
