APPARATUS AND METHOD FOR PRODUCING PURIFIED HYDROGEN GAS BY PRESSURE SWING ADSORPTION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for detecting an operating life of adsorbents in an adsorption tower.;SOLUTION: This invention relates to a method and an apparatus for producing purified hydrogen gas by a pressure swing adsorption process. The apparatus includes: a gas supply unit 3 for adding an inert gas to an unpurified hydrogen gas; and a detector 5 for measuring an inert gas in a purified hydrogen gas discharged from the adsorption tower 1. It is preferable that Ar gas is used as the inert gas.;COPYRIGHT: (C)2012,JPO&INPIT
