Abstract

Es wird ein Verfahren zum Abtrennen unerwünschter Komponenten, wie beispielsweise Stickstoff, Sauerstoff, Wasserstoff und/oder Neon, aus einem unerwünschte Komponenten enthaltenden Helium-Strom, beschrieben, wobei dieser gegen ein Kältemedium zunächst bis auf eine Temperatur, die maximal 8 K über dem Gefrierpunkt der unerwünschten Komponente bzw. im Falle mehrerer unerwünschter Komponenten bis auf eine Temperatur, die maximal 8 K über dem höchsten Gefrierpunkt der unerwünschten Komponenten liegt, abgekühlt (1. Abkühlschritt) und die dabei kondensierende(n) unerwünschte(n) Komponente(n) aus dem Helium-Strom abgetrennt wird bzw. werden, und wobei der Helium-Strom anschließend weiter abgekühlt wird (2. Abkühlschritt), so dass die unerwünschte(n) Komponente(n) ausfrieren, und wobei die Menge und/oder die Zusammensetzung des oder der für den 1. und/oder 2. Abkühlschritt verwendeten Kältemediums bzw. Kältemedien regelbar sind. Erfindungsgemäß wird der Helium-Strom nach dem 2. Abkühlschritt einem der Abtrennung von Wasserstoff und/oder Neon dienenden Adsorptionsprozess unterworfen.

Title
Crude He is heat exchanged with cooling medium to condense impurities and further cooled to solidify remaining impurities. The solidified impities in the He passage are removed by closing the end of the He passage and by passing hot He gas for vaporization of the impurities. Thus curde He contg. 20% *
