Process and installation for the production of ultra-pure oxygen by distillation of air |
摘要 |
A mixture containing oxygen is introduced into a distillation column (1); an intermediate stream, substantially free from impurities heavier than oxygen, is withdrawn (at 17) at a level of the column located above the point (4) of introduction of the air, the point (22) of withdrawal being separated from this point (4) of introduction by a distillation section (6), particularly with packing; the stream withdrawn (at 17) is sent to an oxygen purification column (2), and a reflux liquid is distributed over the section (6) by a distributor (9). A predetermined non-uniformity of the distribution of the reflux liquid over the upper surface (8) of the section (6) is effected in at least one localized region (23) of this surface.
