Nitrogen feed-air systems

Define the nitrogen product first, then collect compatible generator operating data to establish feed-air and treatment requirements.

Product categories to discuss

Choose equipment for the actual process. These links do not establish a required configuration or industry project experience.

Before you buy

  • What uses the nitrogen, and which PSA or membrane generator or process is being considered?
  • What are nitrogen average/peak flow, reference temperature, absolute pressure and moisture basis?
  • How is purity defined, and is the specification total purity or residual oxygen?
  • What outlet pressure, peak duration, operating hours and backup supply are needed?
  • Which maker document gives output, purity, feed pressure, temperature and air quality at one operating point?
Further points to confirm
  • What is the sourced air-to-gas ratio, its flow basis, and which purge or other losses does it already include?
  • What site conditions, existing treatment/storage, utilities and actual gas-purchase costs are available?
  • Nitrogen product flow is not the feed-air requirement.
  • Do not combine low-purity capacity with a high-purity air ratio or count included purge twice.
