Title: Concentration of nitrogen
Inventor: UMEKI MASAKAZU
IPC: C01B13/02
Filed: 1982-07-07
Abstract: PURPOSE:In concentrating nitrogen by pressure swing, to make quickly the concentration of nitrogen gas constant in restarting, by releasing a remaining gas in the inside of an adsorbing device having completed uniform pressure process in the direction opposite to the flow of a raw material gas to the outside of the system under reduced pressure. CONSTITUTION:A raw material gas containing nitrogen gas and at least oxygen gas is alternately sent from the inlet valves 1 and 2 to the adsorbing device 16 packed with molecular sieve coke, the oxygen gas is selectively adsorbed on it, the prepared concentrated nitrogen gas is taken out from the discharge valves 3 and 4, and stored in the storage tank 11. In suspending the device, the valves 1, 2, 3, 4, 7 and 8 are closed, the uniform pressure valves 5 and 6 are opened, the system is in uniform pressure state. The valve 14 is then opened to operate the device, the pressure of the adsorbing device 16 is reduced to atmospheric pressure, and the remaining gas in the adsorbing device 16 is released to the outside of the system. While the valve 15 is opened, the gas in the inside of the adsorbing device 16 is purged by the concentrated nitrogen gas, the valves 14 and 15 are closed, so that the suspension operations are finished. Consequently, the feed of nitrogen gas with a given concentration can be carried out quickly in the restarting of the device.
