When does on-site nitrogen generation make sense versus liquid nitrogen delivery?

The amenability of on-site gas generation involves many factors—nitrogen flow and purity are the most important ones. Flows with a steady or sufficient baseline rate can be great fits for on-sites. Periodic or erratic flow patterns can be amenable if the volumes, pressure and purity are sufficient to allow gas storage that covers peak flows. Also, the lower the purity requirement, the greater the amenability—although high purity is amenable at higher volumes. Other factors include local power cost and pressure required. There are no firm rules defining when to switch from delivery to an on-site. Different on-site options are available to meet your nitrogen requirements, including pressure swing adsorption, membranes or cryogenics.
