Nitrogen Production Method Using Oxygen Selective Adsorbent |
| abstract |
The pressure swing adsorption (PSA) method according to the invention is applied to separate better gas from a mixture of better gas and less good gas. The PSA method employs an adsorptive bed comprising an oxygen equilibrium selective adsorbent composed of one or more layers, pressurizing the adsorptive bed at high pressure using air supplied to allow the adsorptive bed to adsorb oxygen, and at bed pressure Extracting a stream of nitrogen from the bed to store at least a portion of the stream in the product tank, supplying void gas in the bed seal to the storage tank and adsorbing oxygen from the adsorption bed by releasing the adsorption bed into the low pressure region And purging the adsorption bed by supplying the void gas from the storage tank to the adsorption bed, and repressurizing the adsorption bed to an intermediate pressure by flowing the void gas from the storage tank. |
