| 摘要 |
An apparatus and process for producing gaseous oxygen under elevated pressure utilize a distillation column system which has a high-pressure column (106), a low-pressure column (107) located above the high-pressure column (106), and a side condenser (102), which has a liquefaction space and a vaporization space, used to vaporize a liquid oxygen fraction from the low-pressure column (107). The side condenser (102) is located below the high-pressure column (106).
