Abstract

Hollow, semi-permeable fibers which are intended for use in fluid separations have crimps with amplitudes up to 50% of the external diameter of the fiber and an average crimp period of less than 5 cms. The fibers are sufficiently rigid to retain its crimp form during fluid separation. Preferred fibers have an outside diameter of 150-800 microns, a wall thickness of 50-200 microns and a crimp amplitude of 15-250 microns. The tensile modulus is at least 40 kg/mm<2>. The relatively low amplitude crimps enable good fluid dispersion through a bundle comprising substantially parallelly-oriented hollow fibers such that shell-side (i.e., the exterior sides of the hollow fibers) feed of the fluid mixture to be treated can be attractive, even when the flow of the feed is predominantly axial to the hollow fibers. Shell-side feed of the fluid mixture to be treated is often particularly advantageous since the fluid mixture can frequently be recovered from the fluid separation with a relatively low pressure drop.
