Notes

“The hollow fiber type gas separation membrane modules has the hollow fiber element, wherein at least one end of the fiber bundle consisting of multiple hollow fiber membranes having the selective permeability is fixed and bound together with a plate (tube sheet) of a cured resin of cast molding, and the fiber bundle is housed in a vessel equipped with at least a mixed gas inlet, a permeate gas outlet and a non-permeate gas outlet. Besides it functions to fix the fiber bundle together in a single body, the tube sheet has another function to partition the internal space of the hollow fiber membrane from its external space, and to retain the gas-tightness of the internal space and external space by sealing between the hollow fibers and between the hollow fibers and the vessel. The hollow fiber type gas separation membrane module would fail to perform suitable separation if the gas-tightness by the tube sheet were lost.”
