ABSTRACT:
Methods and apparatus for purifying gases having organic impurities, including the use of granulated porous glass. A system for purifying an impure gas includes a source of an impure gas, a purification element operatively associated with the source of impure gas for purifying the impure gas, and a conduit operatively associated with the purification element for receiving a flow of purified impure gas from the purification element and directing the purified impure gas to a container or point of use. The impure gas includes a first gas and an organic compound. The purification element includes a vessel containing a packed bed of granulated porous glass.
