In wide ranging industries from pharmaceuticals to food, high-purity nitrogen becomes crucial for various processes. Companies have traditionally relied on delivered liquid nitrogen or nitrogen cylinders. However, nitrogen generators allow these companies to produce their own nitrogen.

Nitrogen generators are a cost-effective solution for companies to produce nitrogen on-site, which eliminates certain hassles, such as transportation, storage, and handling cylinders. It’s important to understand how these generators work, and how they maximize efficiency and return on investment (ROI).

The Basics Of Nitrogen Generation

Nitrogen generators use one of two processes: pressure swing adsorption (PSA), or membrane separation. Both methods leverage the differences in molecular size and adsorption to separate them from the air effectively.

PSA nitrogen generators operate with compressed air passing through bed adsorbent materials, such as a carbon molecular sieve (CMS) or zeolite. The material absorbs oxygen and allows nitrogen to pass through, resulting in high-purity nitrogen. The system can alternate between adsorption beds, allowing for continuous nitrogen.

Membrane nitrogen generators utilize semi-permeable membranes to selectively permeate nitrogen over oxygen and other gasses. As compressed air flows through the membrane modules, nitrogen diffuses through the membrane walls more rapidly than oxygen, yielding a nitrogen-rich product stream.

Nitrogen Generators Maximize Efficiency

There are several benefits to on-site nitrogen generation for a wide range of industries:

  • When nitrogen is produced on-site, businesses no longer need deliveries and can reduce transportation costs and the carbon emission associated with transportation.
  • Nitrogen generators allow businesses to benefit from a steady and reliable supply of nitrogen that eliminates production downtime from cylinder changes or delivery delays.
  • Nitrogen generators can offer companies a variety of purity levels, ranging from standard industrial levels to ultra-high purity depending on the need.
  • Features such as variable speed drives and optimized process control algorithms minimize energy consumption and operation costs.
  • Nitrogen generators require minimal maintenance with routine filter replacements being the primary task upkeep needed.

How Nitrogen Generation Maximize ROI

  • Producing nitrogen on-site offers cost savings compared to bulk nitrogen supply methods, especially when it’s needed at high volume.
  • On-site production through generators allows businesses to streamline operation, reduce downtime, and enhance productivity. All of this leads to a more efficient operation.
  • Nitrogen generators are a long-term investment that continues to deliver returns over their operational lifespan, with a stable and predictable supply without delivery expenses.
  • Nitrogen generators scale to meet changing production demands, and allow businesses the freedom to adapt their capacity according to the needs of the company.

Choosing The Right Nitrogen Generator

Finding the right nitrogen generator may depend on factors such as the purity or flow rate of the nitrogen you need. Having the right technology for your nitrogen application helps you maintain an efficient business at optimized costs. Tailoring the nitrogen generator to fit your specific needs will help you to maintain efficiency and cost effectiveness.

Here are some other factors you can look at as you work to determine the right system for you:

  • Purity levels – The purity level of nitrogen is a significant factor as you look to select a nitrogen generator. Different industries and processes will require different purity levels. They typically range from 95% to 99.999%. The higher the purity level, the more sophisticated the nitrogen generator you will need.
  • The flow rate – It’s important to think about the volume of nitrogen your operation will require. The flow rate is usually measured in standard cubic feet per minute (SCFM) or standard cubic feet per hour (SCFH) and should match closely with your consumption to avoid inefficiencies or shortfalls. PSA generators have a higher flow capacity than membrane generators.
  • The cost of ownership – It’s important to consider the full cost of ownership as you look for a nitrogen generator, and not just the cost of the equipment. Think about required maintenance, parts availability, and what happens if your generator will need repairs. Consider potential downtime as well.
  • Reliability – You’ll want a generator more known for reliability in order to avoid downtimes. It’s important to read reviews and look for a machine with a track record for reliability and durability.
  • Size and space – Consider the physical size of the generator and the space available within the facility. You’ll want to make sure there is enough room for installation, maintenance, and any potential expansions as your company grows in the future.
  • Scaling – It’s important to consider your future nitrogen needs, too. You’ll want a generator that can be scaled up to meet future needs. Some systems offer modular expansion while others may require a complete replacement.

Find A Nitrogen Generator Company You Can Trust

Nitrogen generators are indispensable for a wide range of industries seeking to optimize the way they procure their nitrogen. By leveraging the new technologies, they are able to take advantage of a cost-effective production solution that eliminates the need for deliveries. With a more efficient result, they’ve become a cornerstone in several industries.

The advantages of nitrogen production go beyond the bottom line. The role of nitrogen generators in business is set to become even more pronounced in the years to come. Compressor Services can help you find a nitrogen generator that suits your specific needs and service it for years to come.
