Abstract

In order to separate oxygen from air, the effects of feed gas flow rate and rinse gas flow rate on the product purity and flow were examined using 2 bed PSA with 4 step cycle. The addition of product pressurization step increased the product purity and flow rate. The addition of pressure equalization increased the product flow rate. The test product was manufactured and the purity and flow rate of product oxygen was examined. The results were compared with the commercial medical oxygen generator of 5 ${\ell}/min$ and 90% oxygen purity.

공기 중에서 산소를 분리하기 위하여 2탑 PSA 공정을 이용한 4단계 기본공정 공급기체의 유량과 세정기체의 유량이 생성물의 순도와 유량에 미치는 영향을 살펴보았다. 4단계 기본 공정에 생성물가압 단계를 도입하면 생성물의 순도와 유량을 증가시키고, 압력균등화단계를 도입한 경우에는 생성물의 유량이 크게 증가한다는 사실을 확인할 수 있었다. 현재 상용화되어 있는 의료용 산소 발생기 사양인 5 ${\ell}/min$ 유량에서 순도 90%의 산소를 얻기 위해 시제품을 제작하여 산소의 순도 및 유량에 관한 실험을 수행하였다.
