摘要 |
A module having polymeric gas-separation membranes is capable of operation in extreme temperature environments. In one embodiment, the module includes polymeric fiber membranes, a tubesheet for holding the membranes, and a sleeve encasing the membranes, all of which are made of materials having coefficients of thermal expansion which differ from each other by not more than about 10%. In another embodiment, the membranes, the tubesheet, and the sleeve are all made of materials having a glass transition temperature greater than a highest anticipated temperature of operation of the module. In another embodiment, the module includes a head, and a clamshell having multiple protrusions which engage corresponding grooves in the head and in at least two grooves formed in the tubesheet. |
