temperature peak like those generated by the adsorption of 10% CO2 by volume, nevertheless a gradual saturation of adsorption sites can be seen in Figure 4.3. In Figure 4.3, the top two charts (labeled as Test 1) show the mass and heat transfer performance illustrated in Figure 4.2. As the experiment is repeated by switching the solenoid valve (40 s for the feed stage, and 60 s for the purge stage), the CO2 adsorption temperature peaks start to gradually disappear from the heat transfer data (right), simultaneously decreasing the adsorption time (left). The adsorption sites become unresponsive to the change in concentration of CO2 in the microchannel, reflected by the minimal change in temperature. Once CO2 adsorption is suppressed in the upstream sites, the net adsorption capacity of the adsorbent layer decreases and therefore the feed CO2 appears in the outlet stream earlier than in the preceding experiment. For the experimental conditions illustrated in Figure 4.3, it is found that after 32 repetitions, all the adsorption sites are blocked by water and no CO2 can be adsorbed by the PLOT column. This observation leads to the conclusion that trace water present in the gas cylinder must be entirely removed to obtain a repeatable set of heat and mass transfer data that can be correlated with the model results. To achieve this, DrieriteTM units are installed upstream of the microchannel. 110PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
