  • Apparatus and method for protecting gas separation membranes from damage due to a reversal of differential pressure
    Patent number: 4808199
    Abstract: An improved method for using a membrane to separate gases provides for relieving the pressure on the permeate side of the membrane when the permeate pressure exceeds the feed pressure by a selected amount. Gas separation apparatus in general and, in particular, spiral wound membrane units are improved by providing for relief of such reversed pressure differentials. A suitable device for relieving the reversed pressure differential includes a body, a poppet movably mounted to the body and biased to a closed position until the selected pressure differential is reached, and a seal for preventing gas flow through the device when the poppet is closed.
