Abstract (en)
[origin: FR2853723A1] System for the purging of residual oxygen at the base of a column used for the cryogenic separation of air. Treatment of a liquid bath(5) containing at least 70% mol of O2 recovered at the base of a column(1) or element (3) of a cryogenic distillation columnmaking up part of a column system for the separation of air ; a continuous vaporiation of the liquid is effected by means of a primary vaporiser(6) in aluminum and part of the bath is purged to avoid an accumulation of inflammabe impurities.The purged quantity is conveyed to a second vaporiser(13), and the vaporised O2 is returned to the column(1).Part of the liquid O2 treated by the second vaporiser is purged, The second vaporiser is constructed of material less inflammable than the first. An independent claim is also included for the installation for the process.
