Abstract

PURPOSE: To reduce required driving power per unit product and to improve production efficiency by utilizing the initial waste gas of a gas releasing state for a pressure equalizing stage of the other adsorption tower and including the remaining waste gas through a compressor into gaseous raw material.
CONSTITUTION: In the stage when an adsorption tower 11 completes an adsorption stage and an adsorption tower 13 completes a desorption stage, valves 21, 31, 73, 63, are closed, and valves 81, 91, 83, 93 are opened to flow the gases in the towers from the tower 11 to the tower 13 and to equalize the pressure in both adsorption towers. After this, the valves 81, 91, 83, 93 are closed, the valves 41, 51, 33 are opened, and the tower 11 starts a gas releasing stage and the tower 13 an equalizing stage. The waste gas E during the gas releasing stage is once stored in a tank 6, and joins with the branch flow of an adsorbing component gas D. This gas is included as a return gas F through a gas cooler 9 into the gaseous raw material by a compressor 8 and is utilized for increasing the concn. of the adsorbing components in the supply gas B.
