Abstract

PURPOSE: To increase the concn. of product gaseous O2 and the yield by connecting an adsorption tower after a desorption process to a pressure equalizing tank, introducing an O2-enriched gas in the tank into the tower to equalize the tank and the tower in pressure, and carrying out an adsorption process in the tower.
CONSTITUTION: An adsorption process is carried out in an adsorption tower 1, and simultaneously a desorption process is conducted in an adsorption tower 2. After finishing the desorption process, an O2-enriched gas is slowly introduced into the tower 2 kept under atmospheric pressue from a pressure equalizing tank 3 in a pressurized state to equalize the tower 2 and the tank 3 in pressure. Then, in the tower 2 adsorption is carried out, and in the tower 1 desorption is conducted to exhaust 26 N2 desorbed from an adsorbent in the tower 1. Air is fed to the tower 2 through a compressor 4 to allow N2 in the air to be adsorbed on an adsorbent in the tower 2, and O2 is fed to the tank 3 and taken out 25 of the system. Thus, a cycle is composed of 4 processes, and by repeating the cycle, O2 in air is concd. and separated.
