초록 | A three-bed PVSA process with two equilibrium beds and one kinetic bed was developed to overcome the 94% O2 purity restriction inherent to air separation in the adsorption process. To produce 97+% and/or 99+% purity O2 directly from air, the PVSA process was executed at 0.33-0.45 to 2.5 atm. In addition, the effluent gas from the CMS bed to be used for O2 purification was backfilled to the zeolite 10X bed to improve its purity, recovery and productivity in bulk separation of the air. In this study, to improve and optimize the cyclic performance of three-bed PVSA process, a parametric study was also done by experimental and theoretical works. The optimization of PR and AD step times of CMS bed was executed to improve both the performance of equilibrium and kinetic separation beds. As a consequence, the high purity O2 of around 97% with high recovery of around 75% and the productivity of around 5.8ⅹ10-5 cm3/g∙sec was produced at properly determined operating condition. |
