Abstract (en)
[origin: EP1284403A1] To produce oxygen, by breaking down air under low temperatures, an oxygen column is used in a distillation system. An initial airflow (2) is relaxed (22) to reduce its working power, and passed into the oxygen column (7). A further feed flow (14) is fed into the head of the oxygen column, with an oxygen content at least equal to the feed air. At least one oxygen product flow (16) is taken from the lower section of the column, and a residual gas flow (17) is extracted at the column head and is relaxed (19). The oxygen column can be part of a twin-column system, as a low pressure column, with a high pressure column (6), and a heat exchange link between them through a condenser/evaporator (8).
