Abstract:
1. A continuous oxygen production method, comprising: (a) adsorbing oxygen using an oxygen-selective adsorption agent by supplying new air into a plurality of adsorption and desorption towers filled with an oxygen-selective adsorption agent, which is BaMg(CO (b) cocurrent depressurizing an inside of the adsorption and desorption tower adsorbed with the oxygen up to an atmosphere pressure; (c) vacuum-desorbing the oxygen adsorbed into the adsorption and desorption tower and collecting the vacuum-desorbed oxygen in an oxygen reservoir; and (d) accumulating the inside of the vacuum-desorbed adsorption and desorption tower up to an adsorption pressure by using the concentrated nitrogen discharged during the adsorption process.
