The results of the simulation runs are shown in Table 3. It can be seen from run 1 (feed pressure: 1 atm), the O2 product throughput obtained by using Li94.2Na0.7Ag1.1-X- 1.0 sorbent was 5.4×10-2 kg O2/ h/ kg-sorbent compared to the throughput of 4.8×10-2 kg O2/ h/ kg-sorbent offered by Li94.5Na1.5-X-1.0 sorbent. The corresponding O2 product purity and recovery were approximately 96% and 62% respectively. There is an improvement of 12.5% in the product throughput which translates into considerable savings in capital and operating costs since a higher product throughput implies a smaller bed requirement for the same desired production. Another run was done at a different feed pressure of 1.2 atm with the cycle conditions optimized to produce O2 product at 90.7% purity and 78% recovery. In this case as well, the product throughput of the Li94.2Na0.7Ag1.1-X-1.0 sorbent was found to be higher (7×10-2 kg O2/ h/ kg-sorbent), compared to that of the Li94.5Na1.5-X-1.0 sorbent (6.3×10-2 kg O2/ h/ kg-sorbent). Thus, the product throughput of the Li94.2Na0.7Ag1.1-X-1.0 sorbent is higher by 11% even at a lower O2 product purity requirement. The values of the throughputs obtained in this study were found to have an order of magnitude agreement with those published for Li- X-1.0 sorbent in literature.31 From the simulated bed profiles, it was observed that temperature deviations from the feed temperature of 25°C due to the adsorption heat effects were about 17°C for the Li94.2Na0.7Ag1.1-X-1.0 sorbent while it was only 12°C for the Li94.5Na1.5-X-1.0 sorbent. However, from the results it appears that the advantage of higher N2 loading on the Li94.2Na0.7Ag1.1-X-1.0 more than compensates the lowering of PSA performance due to higher heat effects. Hence it is evident from the previous two examples that the Li94.2Na0.7Ag1.1-X-1.0 sorbent is superior to the Li94.5Na1.5-X-1.0 sorbent for air separation by PSA. 68PDF Image | PSA USING SUPERIOR ADSORBENTS
