Abstract
A method of and an arrangement for increasing the enrichment of nitrogen in an effluent gas obtained from a pressure swing adsorption system includes electrostatically negatively charging oxygen molecules in a feed gas such as air, and attracting the negatively charged oxygen molecules to a positively charged molecular sieve coke material employed as adsorbers in the pressure swing adsorption process.
