Abstract
PURPOSE:To produce N2 having high purity by connecting both inlet ends and outlet ends of an adsorption-completed adsorption tank and a regeneration- completed adsorption tank with each other and adjusting a ratio of the gas flow rates at a part connecting the exit parts to each other to that at a part connecting the inlet parts to each other to 3-70%. CONSTITUTION:Compressed air is introduced into an adsorption tank 1 and O2 is removed from the air by being adsorbed to molecular sieve coal, and produced N2 is transported to a storage tank 3. On one hand, an adsorption tank 2 is evacuated with a vacuum pump 4, and regeneration operation is processed in the adsorption tank 2. Then, the pressure of the adsorption tanks 1, 2 is equalized. In this stage, exit parts of both tanks and inlet parts of both tanks are connected with each other by opening a valve 11 and 12 at the same time, and the ratio of gas flows at the part connecting the exit parts with each other to that at the part connecting the inlet part with each other is adjusted to 3-70% by adjusting the opening area of orifices 15, 16. Thus, the purity of produced N2 is improved.
