ABSTRACT:
A process for separating nitrogen which comprises, with a nitrogen gas separation apparatus of a pressure-swing adsorption type, a gas transfer step between an adsorber having completed an adsorption step with another adsorber having completed a regeneration step. The gas transfer step further comprising discharging part of the gas being transferred out of the system. This process provides, with compact equipment, high-purity product nitrogen with a purity of at least 99.99%, which has been considered difficult to obtain with conventional pressure-swing adsorption apparatuses.
