Abstract
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).
Claims18
An apparatus for producing gaseous oxygen under elevated pressure comprising:
- a distillation column system having a high-pressure column (106) and a low-pressure column (107), the low-pressure column (107) being located above the high-pressure column (106);
- a side condenser (102) having a liquefaction space and a vaporization space and which is located below the bottom of the low-pressure column (107);
- a feed air line (1, 2, 3, 4), which is connected to the high-pressure column (106);
- at least one transition line (18-19;
- 11-14-15) for introducing a fraction from the high-pressure column (106) into the low-pressure column (107);
- a liquid line (28) for removing a liquid oxygen fraction from the low-pressure column (107), the liquid line (28) leading into the vaporization space of the side condenser (102);
- and
- a product line (29, 30), for removing gaseous oxygen under elevated pressure, which is connected to the vaporization space of the said side condenser (102);
- wherein the side condenser (102) is located below the high-pressure column (106).
A process for producing gaseous oxygen under elevated pressure in a distillation column system, having a high-pressure column (106) and a low-pressure column (107), the low-pressure column (107) being located above the high-pressure column (106), said process comprising:
- introducing a feed gas (1, 2, 3, 4) into the high-pressure column (106);
- introducing at least one fraction (18-19;
- 11-14-15) from the high-pressure column (106) into the low-pressure column (107);
- introducing a liquid oxygen fraction from the low-pressure column (107) into a vaporization space of a side condenser (102), said side condenser having a liquefaction space and a vaporization space and is located below the bottom of the low-pressure column (107);
- and
- withdrawing gaseous oxygen (29, 30) from the vaporization space of the side condenser (102), wherein the side condenser (102) is located below the high-pressure column (106).
