- 흡착탑의 하부에는 공기중의 수분을 제거하기 위한 활성알루미나를, 상부에는 질소를 선택적으로 흡착하는 합성제올라이트 분자를 충전할 3기의 흡착탑을 이용하여 압력변동흡착법에 의해 공기로부터 산소를 제조하는 방법에 있어서, 흡착공정이 완료된 제 1 흡착탑 AD-I에 제품산소를 제품탱크(R40)로부터 탑의 상부로 도입하여 흡착압력부근까지 축압하는 축압공정과, 제 2 흡착탑 AD-II의 제 2 흡착공정 후 탑의 상부에 잔류하는 산소성분을 축압공정이 완료된 탑으로 회수하기 위하여 원료공기를 제 2 흡착탑 AD-II 하부에서 계속해서 도입하면서 탑의 상부로 배기되는 농축산소성분을 제 1 흡착탑 AD-I의 하부로 도입하면서 상부로부터 제품산소를 회수하는 제 1 흡착공정과, 제 2 흡착공정 후 탑의 상부에 잔류하는 농축산소를 축압공정이 완료된 제 3 흡착탑 AD-III으로 회수하기 위하여 원료공기를 제 1 흡착탑 AD-I 하부로부터 도입하여 상부로 배기되는 농축산소를 제 3 흡착탑 AD-III의 하부로 회수하는 회수공정과, 축압공정에서 회수공정까지를 수행하여 질소성분으로 포화되어 있는 흡착탑을 진공펌프로서 감압탈착하므로써 흡착탑을 재생하는 탈착재생공정을 제 1 흡착탑 AD-I에서 제 2,3의 흡착탑 AD-II, AD-III에 공정위상이 서로 다르게 순차적으로 반복해서 행하는 것을 특징으로 하는 산소제조방법.
- 제 1 항에 있어서, 탈착재생이 완료된 흡착탑을 제품산소로서 축압할 때 가스의 탑내유속을 7Cm/sec 이하로 하는 것을 특징으로 하는 산소제조방법.
