Abstract

The impurities present in the feed gas to a helium liquefier must be reduced to very low levels in order to prevent solid deposition and eventual plugging. The removal of these impurities is usually accomplished in fixed bed adsorbers at cryogenic temperatures. In spite of the importance of these adsorbers, relatively little information is available regarding the equilibrium capacity of an adsorbent for an impurity carried in a helium gas stream. Pertinent design information of cryogenic adsorbers for the purification of hydrogen is available in the literature [1–7]. The present study was undertaken to obtain information for the design of adsorbers used in helium liquefiers.
