  • Pressure relief system for treating fibrous materials under pressure
    Patent number: 5645690
    Abstract: A process and apparatus is disclosed for treating fibrous material under pressure which includes at least two pressure relief devices. The pressure relief devices are arranged so that only one at a time is exposed to pressure during the treatment process. When the exposed pressure relief device is ruptured in response to an abnormal increase in pressure, the ruptured device may be isolated and the second pressure relief device exposed to the operating pressure so that the treatment apparatus may be operated on a substantially continuous basis.
