Abstract
Le super purificateur de l'invention comporte des moyens pour mettre en contact un azote gazeux contenant des impuretés avec un dégazeur constitué d'un alliage contenant de 15 à 30 % en poids de fer et de 70 à 85% en poids de zirconium. Le procédé de la présente invention consiste à mettre en contact un gaz contenant des impuretés avec un tel dégazeur. L'invention concerne particulièrement un super purificateur et un procédé pour purifier un gaz contenant des impuretés jusqu'à une pureté plus élevée que celle obtenue par les procédés de purification conventionnels.The super-purifier of the invention comprises means for bringing a nitrogen gas containing impurities into contact with a degasser consisting of an alloy containing 15 to 30% by weight of iron and 70 to 85% by weight of zirconium. The process of the present invention consists in bringing a gas containing impurities into contact with such a degasser. The invention particularly relates to a super-purifier and a method for purifying a gas containing impurities to a higher purity than that obtained by conventional purification methods.
