ABSTRACT:
Disclosed is a fluid separator comprising a shell filled with a bundle of hollow fibers having a selective permeability, wherein a majority of the hollow fibers each has on the periphery thereof 1 to 10 fins extending in the longitudinal direction, and the occupancy ratio y of the sections, defined by the peripheries, of all the hollow fibers exclusive of the fin portions in the hollow fiber bundle to the section, vertical to the axial direction of the hollow fiber bundle, of the inner wall of the shell is within a range defined by the following formula (I): ##EQU1## wherein x stands for the average fin number per hollow fiber in the hollow fiber bundle, and .alpha. indicates the ratio H/d of the average fin height H(.mu.) in the hollow fiber bundle to the average outer diameter d (.mu.) of the hollow fibers exclusive of the fin portions.
