HYD10A is most commonly used to remove contaminants such as water, carbon dioxide, and hydrocarbons from feed gas in air pre-purification units prior to cryogenic air separation. This molecular sieve will also remove hydrogen sulfide, mercaptans, and high molecular weight sulfur compounds in LNG, LPG, and liquid hydrocarbon streams, such as propane and butane. HYD10A can also be used to deeply dehydrate compressed air, instrument air, inert gases, to purify ammonia synthesis gas, or to remove odorous sulfur compounds from aerosol propellants.
