Advantages of Nitrogen Generator

Low long-term operating cost: Cutting out the repeating operating costs of tank rental, delivery, and administration adds up to big long term savings. These savings multiply for more intensive N2 requirements.

No supply constraints: A membrane Nitrogen generator only requires a line of compressed uses the ambient air to complete its process supply a continuous flow of pure Nitrogen gas. It does not need to be plugged into an electric power supply.

Adjustable purity and flow rate: Control the flow rate and purity of the nitrogen rests to fit your specific application needs.

Compact and portable: A nitrogen generator has a small, unchanging footprint—its slim tower design takes up less floor space than a set of canisters.

Low maintenance: It takes no reloading or moving around—it’s a one-and-done kind of device until it needs a filter change in about 5-10 years.

Efficient: Every drop of the nitrogen it produces can be used—no more almost-empty tanks.

Types Of Nitrogen Generator

Pressure swing absorption technology

We deploy two types of nitrogen generator technologies. The first of which is pressure swing adsorption technology. PSA nitrogen generators are machines that separate nitrogen gas from atmospheric air. They are used in various industries to produce nitrogen gas on-site, which can be used for a variety of purposes such as food packaging, laser cutting, and welding.

Membrane Filtration Technology

The second type of nitrogen generators are known as membrane generators. These are machines that separates nitrogen gas from the air we breathe. It does this by using a special material called a hollow porous fibre. This fibre has tiny holes in it that allow nitrogen to pass through but keep other gases like oxygen and water vapor out. So, when air is pushed into the generator, the nitrogen is separated from the other gases and collected in a tank.

How Does A Nitrogen Generator Work

Air Compression
The process starts with an air compressor that sucks in air from the surrounding environment and compresses it to a certain pressure. The pressure required is dependent on the type of generator and the level of purity required, and is usually between 5 and 10 bar for most PSA systems.

Air Pre-Treatment
The air that is to be separated is first pre-treated to eliminate any unwanted materials that may be present. This entails filtering the air to eliminate dust, particles, and oil and then using an air dryer to eliminate moisture.

Gas Separation Process
In a membrane nitrogen generator, the compressed air is taken through membrane systems where oxygen molecules, water vapor and other impurities are separated from the nitrogen.

Nitrogen Storage (Optional)
In cases where nitrogen is needed continuously, the generated nitrogen is stored in tanks. This storage helps to maintain a steady rate of flow even if there is a temporary increase in the rate of flow.

Nitrogen Post-Treatment (Optional)
In some cases, nitrogen may be subjected to final treatment, which may involve further purification to remove any residual impurities to achieve a certain level of purity for specific applications.

Key Components of a Nitrogen Generator

Component	Description
Air Compressor	The most important component, responsible for compressing environmental air to the required pressure for nitrogen separation. The size and type of the compressor determine the generator’s efficiency and power output.
Pre-filters	The first stage of filtration that removes large particles, dust, and oil aerosols from compressed air. This protects downstream components and ensures nitrogen quality.
Air Dryer	Removes water vapor from compressed air using refrigerated or desiccant dryers. This protects the adsorbent material in PSA systems and improves membrane system efficiency.
Separation Unit	The core unit for nitrogen generation, which can be a membrane nitrogen generator or a PSA nitrogen generator using a molecular sieve for adsorption.
Control System	The central control unit that manages pressure, flow rates, and adsorption vessel switching in PSA systems. It may also include advanced automation features.
Nitrogen Storage Tank	An optional but essential component that stores produced nitrogen, ensuring a steady supply despite usage variations.
Post-Filters	The final filtration stage that removes any remaining fine particles or impurities, ensuring the nitrogen meets the required quality standards.

Applications of Nitrogen Generators in Various Industries

Pharmaceutical Industry
Nitrogen gas is used in the pharmaceutical industry in various ways such as in packaging of drugs, storage of drugs, and in laboratory uses. High purity nitrogen helps to avoid oxidation of the product, moisture content and microbial growth, thus enhancing the stability and safety of the product.

Fire Protection Industry
In the fire protection industry, nitrogen gas is used to help reduce the effects of corrosion in fire sprinkler systems. This is because when oxygen rich air is replaced with nitrogen molecules in the sprinkler pipes, the chances of corrosion are greatly reduced thus increasing the life span of the system.

Food and Beverage Industry
In food packaging, nitrogen gas is used to create an environment that reduces the rate of oxidation and microbial activities hence increasing the shelf life of the food. Cylinders of nitrogen were used in the past but the current membrane nitrogen generator systems are cheaper and supply nitrogen in a continuous flow for the packaging lines.

Electronics and Manufacturing
Some of the industries that use nitrogen include electronics manufacturing, laser cutting, and gas chromatography where nitrogen is used to minimize contamination and oxidation. A nitrogen generator system provides a consistent temperature of nitrogen and the flow rate of nitrogen is also controlled, which enhances the production process.

Oil and Gas Industry
PSA nitrogen generators are used in the oil and gas industry to ensure that storage tanks and pipelines are filled with an inert gas. This is because when oxygen is replaced with pure nitrogen, the chances of combustion and oxidation are greatly minimized.

FAQ

Q: Are nitrogen generators reliable?

A: Nitrogen generators are highly reliable for continuous operation. These systems can offer uninterrupted nitrogen supply with customizable purity levels to meet diverse industrial needs.

Q: What is the life expectancy of a nitrogen generator?

A: PSA nitrogen generators are typically designed with an equipment life cycle of 20 to 25 years. Membrane nitrogen generators also have a long life cycle.

Q: What can you do with a nitrogen generator?

A: A nitrogen generator is used to create on-demand nitrogen gas by separating it from the air, which is then used for applications that require an inert atmosphere to prevent oxidation or other unwanted reactions. Common uses include food packaging to extend shelf life, electronics manufacturing to prevent corrosion, and industrial processes like laser cutting, heat treating, and automotive tire inflation.

Q: What is the capacity of a nitrogen generator?

A: Nitrogen generators produce nitrogen gas from compressed air and offer a cost-effective, reliable and safe alternative to traditional nitrogen gas supplies such as cylinder or liquid. Nitrogen generators are available in 6 standard models with capacity in the range from 1 - 115 m3/hour from 95% to 99.9995% purity.

Q: How to use a nitrogen generator?

A: Nitrogen generators need compressed air, so the first step of using a nitrogen generator is connecting the generator to an air compressor. Once the pressured air enters the system, the generator will separate the nitrogen molecules from elements such as oxygen, water, carbon dioxide and argon.
