HOLLOW FIBER ELEMENT FOR SEPARATING ORGANIC VAPOR

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber element for separating organic vapor which has durability of sufficiently holding air-tightness between an internal space and an outer space of a hollow fiber membrane even in use under organic vapor of high temperature and high pressure.SOLUTION: In a hollow fiber element constituting a separation membrane module for separating organic vapor, at least one end part of a fiber bundle formed of many hollow fiber membranes having selective permeability is fixed and united by a tube plate formed of a metal with a melting point of ≥170°C and <300°C.
