摘要:
A process is described for nitrogen recovery from air using vacuum swing adsorption. The process minimizes capital costs by reducing or eliminating gas storage vessels and reduces power requirements by operating without an air feed compressor or elevated pressure feed, whereby air feed is induced by vacuum conditions achieved by pressure equalization between parallel adsorption beds. Alternatively, a minor amount of oxygen product can be recovered.
