PROCESS FOR SUPPLYING NITROGEN FROM AN ON-SITE PLANT The present invention relates to a process for supplying nitrogen from an on-site plant, which is not necessary in an air separation plant. The plant which might be a chemical plant, an oxygen plant or an oxygen/nitrogen plant, must have compressor means available for other purposes, such as air instrument compressor means. This compressor means is oversized relative to the need of compressed air in the plant to feed a nitrogen membrane which delivers nitrogen gas having a purity, flowrate and/or pressure adaptable to customers' needs.
