METHOD OF PURIFICATION OF KRYPTON AND XENON Russian patent published in 1995 - IPC

Abstract RU 2032870 C1

FIELD: cryogenic engineering. SUBSTANCE: primary krypton concentrate is subjected to preliminary cooling before separation to temperature below -115 C in heat exchanger and before final cooling, it is additionally cleaned in absorber at V_gas/V_adsorb = 190-250 l/h, where V_gas is flow rate of gas through absorber, V_adsorb is volume of absorbent in absorber. EFFECT: enhanced efficiency. 2 cl, 1 dwg
