this, the solenoid valve is switched to activate the purge gas stream. The purge gas flow is continued for approximately 60 s. The purge stage time is deliberately varied by ±5 s to observe its effects on the adsorption time and temperature rise during adsorption. The solenoid valve is switched to the impure feed gas stream again after the end of the purge duration. A forced convection oven with a maximum attainable temperature of 225°C (Rickly Hydrological Company) and a vacuum pump (JB Platinum® series, DV-200N) are used to remove trace water from the adsorbent-coated microchannels for 10 hours before each experiment. All the components and sensors are connected using stainless steel Swagelok 1⁄4‖ fittings along with ball valves to shut-off and needle valves to restrict the gas flows at appropriate locations as shown in Figure 4.1(a). Additionally, laboratory DrieriteTM units are installed in the paths of feed gas and purge gas streams to remove trace water vapor present in the gas mixture, before the streams enter the microchannel. The rationale behind the use of desiccants in the experiments, despite the use of research grade cylinders, is explained in a later section. The PLOT column section of the chosen length is cut without causing any damage to it from the procured column of 30 m length for each experiment. This column is then carefully attached to the fittings, which are installed in the oven as shown in Figure 4.1. For the preparation of the test section, an end of the PLOT column is closed, while another end is connected to the vacuum pump. The PLOT column is heated in the oven at 225°C for about 10 hours, and the vacuum pump decreases the pressure in the column to 10 Pa absolute. Due to a very low pressure and high temperature, any contaminants and water vapor that may have entered the test section previously are removed. Once this first regeneration is complete, the PLOT 106PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
