摘要：PROBLEM TO BE SOLVED: To provide a method for separating and recovering oxygen-enriched air from air with good separation efficiency using a spiral type gas separation membrane module that has a simple structure, and to provide a spiral type gas separation membrane module suitably used for the method.SOLUTION: The method for separating and recovering oxygen-enriched air from air separates and recovers the oxygen-enriched air from a hollow part of a core tube by reducing the pressure of the hollow part of the core tube to 95 kPaA (absolute pressure) or low by a pressure reducing means while sending air into a raw material gas passage by a blower means so that the value gained by dividing the maximum blast weight and maximum static pressure with an effective membrane area of the gas separation membrane is 100 m/min×mor below and 4,000 Pa/mor below respectively using a gas separation membrane module composed by spirally winding a set of laminates made by inserting the permeation side spacer that is a permeation gas passage communicated with the hollow part of the core tube to discharge collected permeation gas between two sheets of flat membrane-like gas separation membranes and the supply side spacer that is a raw material gas passage around the core tube so that they are piled up alternately.
