<p>According to this process, after the nitrogen originating from the low pressure column (11) is heated, it is compressed to the high pressure by means of a single nitrogen compressor (7) and the low-pressure column (11) is operated at a pressure of the order of PN/ rho N, where PN denotes the high pressure of nitrogen and rho N the compression ratio of the said nitrogen compressor. Application to the simultaneous production of, on the one hand, nitrogen of high purity at a pressure of between 50 and 60 bars and, on the other hand, oxygen at 65 bars, to feed a unit for producing ammonia. <IMAGE></p> |
