  • Process and system for purifying gases
    Patent number: 6824752
    Abstract: This invention is directed to a system and a process for protecting a gas purification system from damage comprising passing a stream of impure gas through a catalyst bed and measuring the temperature difference before and after the catalyzed bed reaction through a data analyzer to determine the impurity of the gas prior to controlling the feed of impure gas into or out of a reactor for producing a purified gas. In a preferred embodiment, the catalytic beds may be in parallel form, and the plurality of temperature measurements before and after the catalytic beds is considered by a data analyzer for controlling the impure gas for feeding into the purification reactor.
    Type: Grant
