PURPOSE & OPERATION

What the package does

On-site nitrogen generation separates nitrogen from a compressed-air feed using pressure swing adsorption or membrane technology. The package supplies nitrogen for duties such as inerting, tank blanketing and purging at the required process purity and delivery pressure.

ENGINEERING & INTEGRATION

How it fits your facility

Technology selection is driven by flow, purity and the compressed-air supply available at the facility. Feed filtration and drying, buffer storage, distribution and online purity monitoring are coordinated within the package. Area classification and utility interfaces are confirmed for the installation.

Typical process sequence

  1. Compressed air feed
  2. Filtration & drying
  3. PSA / membrane separation
  4. Nitrogen buffer vessel
  5. Distribution header

Illustrative sequence; final equipment and routing follow the agreed process design.

Typical applications

  • Tank blanketing
  • Purging
  • Process inerting

Package considerations

  • PSA or membrane technology
  • Purity to suit the process
  • Skid-mounted configuration

Design inputs to prepare

  • Nitrogen flow
  • Required purity
  • Delivery pressure and utilities

The final process configuration, materials, design codes and performance requirements are established against the agreed design basis and client specification.
