<p>PROBLEM TO BE SOLVED: To obtain a simple inexpensive adsorber by forming a shell of an adsorber packed with an adsorbent suitably used in an air separation plant for separating air into oxygen and nitrogen by an adsorption method of a flexible material. SOLUTION: This adsorber 1 has a shell 3 made of a flexible material having the performance of gas cutoff packed with an adsorbent and if necessary, other packings, and it is constituted so that pressure (external pressure) applied on the adsorber 1 by the atmosphere is received by the adsorbent 2 through the shell 3. The shell 3 is provided in both the lower and upper end parts with connecting pipes (nozzles) 4, 5 which become a gas inlet and a gas outlet respective. As a material for the shell 3, nylon, polyethylene, polyvinyl chloride or the like is cited. The adorbent 2 is formed into sphere, cylinder cube, rectangular or the like in advance to make it an adsorbent formed material having a prescribed shape, and the outer surface thereof is covered with a gastight treating material (a sealant) to make it the shell 3.</p> |
