초록

Process for obtaining nitrogen from air or nitrogen-containing gases by pressure exchange adsorption and desorption on two alternately operated adsorbers filled with carbon molecular sieves, whereby air is passed through the adsorber so that the oxygen is adsorbed and enriched nitrogen is obtained, while at the same time the other adsorber is regenerated by pressure relief, whereby in a first carbon molecular sieve layer (on the air intake side) of the two adsorbers, making up 1/20 to ½of the entire carbon molecular sieve layer, a carbon molecular sieve ...

A process for obtaining nitrogen from a feedstock gas selected from the group which consists of air and nitrogen-containing gases, comprising the steps of: (a) operating a pair of pressure swing absorbers alternately so that one of said adsorbers is traversed by the feedstock gas, oxygen is preferentially adsorbed therein, and nitrogen is obtained in an enriched form, while simultaneously regenerating the other of said adsorbers by relieving pressure therein; (b) providing on a feedstock-gas intake side of each adsorber, a first carbon molecular sieve la...
