Beschreibung
Zusammenfassung:	The present invention is directed to a method and system of purifying hydrogen supplied from a storage cavern, particularly to removing methane and other hydrocarbons from the hydrogen withdrawn from the cavern by using selective adsorption. The adsorbed impurities can be removed from the adsorbent by increasing the temperature, reducing the pressure, or a combination of both. La présente invention concerne un procédé et un système de purification d'hydrogène fourni à partir d'une caverne de stockage, en particulier pour éliminer le méthane et d'autres hydrocarbures de l'hydrogène extrait de la caverne à l'aide d'une adsorption sélective. Les impuretés adsorbées peuvent être éliminées de l'adsorbant par augmentation de la température, par réduction de la pression, ou par une combinaison des deux.
