  • Ultra pure gases: removal of halocarbons, fluorocarbons, and sulfur compounds from gas streams
    Patent number: 6074459
    Abstract: A process for removing sulfur-containing compounds and halocarbons such as fluorocarbons and chlorocarbons from gases to provide gas streams which contain these compounds at unprecedentedly low levels using an adsorption train of four beds has been developed. The first bed serves to remove water, the second and third beds remove sulfur-containing compounds generally, and the fourth adsorbent bed removes sulfur-containing compounds and halocarbons such as chlorocarbons and fluorocarbons to very low levels.
