Abstract

In the purification of Kr/Xe (Krypton / Xenon) solely by distillation it is necessary, on safety grounds, to use nitrogen to strip oxygen from the raw Kr/Xe/hydrocarbon stream. The idea is to obtain this nitrogen by flashing the LP column LIN reflux stream to an intermediate pressure and using the intermediate pressure flash gas as the stripping gas.
