HIGH PURITY OXYGEN GENERATION THROUGH MODULAR STRUCTURED RAPID PRESSURE SWING ADSORPTION (RPSA). THE OVERALL GOAL OF THIS PROJECT IS TO DEVELOP A NOVEL SINGLE-STAGE DUAL-LAYER RAPID PRESSURE SWING ADSORPTION (RPSA) PROCESS FOR HIGH PURITY OXYGEN PRODUCTION. THE HIGH PURITY OXYGEN PRODUCTION THROUGH INTEGRATED CYCLIC RPSA PROCESS WILL BE ADVANCED FROM A TECHNOLOGY READINESS LEVEL (TRL)-3 TO TRL-5 TO VALIDATE ITS POTENTIAL FOR FUTURE SCALE-UP IN SUBSEQUENT PROGRAMS.
