APEX services overview

When a need for short-term or emergency industrial gas supply occurs—particularly during start-ups, peak demand periods, planned or unplanned maintenance activities, and plant or pipeline turnarounds—you need help quickly to remain online and productive. For over 40 years, customers have come to rely on Air Products’ APEX Industrial Nitrogen Supply Services for fast, reliable temporary gas supply.

We can provide your entire nitrogen requirement or supplement your on-site or pipeline nitrogen source. Emergency or spot nitrogen supply can help you shorten costly turnarounds and avoid losses from having to suspend operations due to the shutdown of your primary nitrogen source. It can also help you maximize profits by supplementing your own nitrogen supply to boost production during periods of peak demand.

Let our experience help you to succeed and meet your needs for:

  • Purging, inerting or blanketing of process equipment, piping systems and storage tanks
  • Cooling of catalytic reactors, heat exchangers and cryogenic equipment
  • Drying of process equipment, including piping systems, heat exchangers, reactors and molecular sieve beds
  • Plant commissioning or decommissioning
  • Pressure testing of piping systems, gas storage, process equipment and tube banks
  • Product displacement or O2-freeing in pipelines
  • Pipeline pig pushing or "pigging"
  • Catalyst change-outs and inert entry support
  • Water removal and drying after hydrotesting
