HIGH PURITY OXYGEN GENERATOR Blake Ashcraft and Jennifer Swenton Executive Summary The objective of this project is to determine whether or not it is feasible to build an oxygen supply device using silver zeolites to separate nitrogen and argon from oxygen for >99% purity. The goal is to introduce a design into different markets to determine profitability over time. Two consumers were focused on during the stint of the project. This produced two designs, a portable unit for individuals and a stationary unit for hospitals. Both designs incorporate the use of Pressure Swing Adsorption (PSA) with silver zeolites as the adsorbents. A portable unit that can sustain a constant flowrate of 5 L/min at 99% purity was determined to be achievable. Preliminary estimates have shown the portable unit will cost approximately $4,200 and weigh 20.5 pounds. Future investigation is required to determine consumer preference and the economics. The hospital unit utilizes a PSA system and is successful of producing >99% oxygen with a split bed
