ABSTRACT:
A process and an apparatus for removing impurities from liquified gases at cryogenic temperatures is provided which can be utilized on site at every stage of transport and storage subsequent to manufacture and prior to use. Liquified gas to be purified which is at cryogenic temperatures is passed preferably through a prefilter to remove solid particulates, followed by passage through an adsorbent bed to remove impurities from the gas and then through a postfilter to remove any entrained particles of adsorbent material from the gas stream. The process can be made continuous between, for example, a storage tank and an adsorption device. The apparatus includes at least one chamber having adsorbent material substantially filling it. A prefilter removes particulates upsteam of the adsorbent chamber and a postfilter downstream of said adsorbent chamber removes entrained adsorbent bed material. Use of two or more adsorbent chambers permits regeneration of one or more chambers while the remaining adsorbent chambers are being used for adsorption.
