How on-site Nitrogen generation reduces your operating costs

The true cost of traditional gas supply

Traditionally, most businesses obtained nitrogen through a delivered supply in the form of bulk liquid N2, dewars, and high pressure compressed gas cylinders. However, relying on outside vendors can pose several challenges, not least long-term purchase commitments, inflexible delivery schedules, uncontrollable vendor price increases and tank rental fees. With regard to cylinders and dewars, the gas supply is interrupted when changeouts are necessary, and it is not uncommon to run out of supply due to a late or missed delivery.

Additionally, precautions must be taken when handling and storing high pressure compressed gas cylinders. Approximately 10% of the gas in every cylinder is typically returned to the supplier unused and liquid ‘boil-off’ vents the expensive gas into the atmosphere.

What are the benefits of on-site nitrogen generation?

The benefits of on-site N2 generation to you are enormous and the payback on investment is very attractive.

You are in control

On site generation enables you to produce your total demand for nitrogen gas on your premises and under your complete control, providing quality and volume on demand. As a result, you can generate as much or as little nitrogen as needed. The modular design of the NITROSourceTM system also means you can expand the system should your demand grow. Nitrogen generation packages are available as capital purchase or for long term rental to suit your budgets and facilitate planning.

Positive contribution to the bottom line

When the true costs of traditionally sourced nitrogen are accounted for, gas generation is the most economical source of nitrogen. When you switch to gas generation, you can expect payback within 6 to 24 months, depending on your existing arrangements and consumption. You’re also making an investment in quality through uninterrupted supply, stable gas pressure, consistent flow and guaranteed purity.

Sustainable for the environment

Gas industry sources indicate that an air separation plant uses 1976kJ of electricity to produce 1kg of liquid nitrogen. Generation of 99.9% nitrogen gas in house using a PSA system is 1420 kJ. That means that up to 28% fewer greenhouse gases are created by the generation of electricity with a typical nitrogen generator. At a purity of 98%, the energy required for in house nitrogen drops to 796 kJ/kg. That means that in house generation creates 62% fewer greenhouse gases from electrical power at that purity.

How can you achieve these benefits?

“We are set to recoup the capital cost within 18-24 months. So effectively we’ll be producing free nitrogen on-tap, without the risk of production downtime.”

Parker's nitrogen generation systems continuously produce high purity nitrogen from compressed air and eliminate the inconvenience of a delivered nitrogen supply. Installation is simple: pipe in compressed air and pipe out nitrogen. Just connect a standard compressed air line to the inlet of the generator, connect the outlet to your nitrogen line and the unit is ready for trouble free operation. The system is designed to operate 24 hours/day, 7 days/week. These Parker nitrogen generators are free standing, housed in a cabinet or skid mounted, depending on the application. Standard features include high efficiency coalescing prefilters with automatic drains, activated carbon adsorption (when required), nitrogen storage tank and a 0.01 micron final membrane filter. There is also a range of oxygen monitors to measure the oxygen concentration of the nitrogen stream to meet your application requirements.

And just in case you didn't know the science.....

Nitrogen gas makes up about 78 percent of the Earth’s atmosphere and is applied in a variety of industrial uses, from the food industry, to drug manufacturing. Nitrogen gas is a compound that forms from elemental nitrogen, found throughout the planet’s atmosphere and in most biochemical reactions. One of nitrogen’s unique properties is its ability to form multiple bonds with various other elements and compounds. This has made it incredibly versatile. It is commonly used in industry as a clean, dry, inert gas, primarily for displacing oxygen from products and/or processes. Industrial applications in food, material processing, pharmaceuticals and electronics include:

Packaging in the food and beverage industry to prevent oxidation and spoilage of food and drink
Manufacturing transistors, circuits and diodes
In manufacturing steel to prevent oxidation
Welding and metalworking to prevent oxides and waste compound formation
