METHOD AND FACILITY FOR PRODUCING OXYGEN THROUGH AIR DISTILLATION |
摘要 |
In a method for producing oxygen through the distillation of air supplied by air at atmospheric pressure so as to produce a first and second compressed air flow, and through a first purification unit (5) and a second purification unit (7), the first and second compressed air flows being discharged from the compression means at a first and second pressure, the first and second pressures being different pressures of at least 0.5 bar: the first compressed air flow is sent from a first outlet of the compression means to the first purifying unit at the first pressure so as to produce a first purified air flow; the first purified air flow is sent from the first purifying unit to a column of the column system (15); the second purified air flow is sent, in an at least partially condensed form, from the second purifying unit to a column of the column system; an oxygen-rich liquid is bled off from the column system; said oxygen-rich liquid is vaporized through heat exchange with at least the second purified air flow; and said oxygen-rich liquid is provided as a material. |
