2. Working Principles for PSA Nitrogen Generator

Adsorption: Compressed air, containing a mixture of nitrogen and oxygen, enters the PSA nitrogen generator and passes through a vessel filled with a carbon molecular sieve (CMS) adsorbent material. The CMS selectively adsorbs oxygen molecules, allowing nitrogen to pass through and separate from the air stream.

Nitrogen Production: The nitrogen-enriched gas flows through the vessel, exiting as the desired product while the oxygen is retained by the CMS material.

Desorption: As the CMS bed becomes saturated with oxygen, the pressure inside the vessel is reduced to release the adsorbed oxygen molecules. This desorption process regenerates the CMS bed for further nitrogen production.

Purge Cycle: To ensure complete removal of residual oxygen and maintain nitrogen purity, a portion of the produced nitrogen is redirected back into the vessel. This purge gas helps to sweep out any remaining oxygen molecules from the system.

Repeat Cycle: The adsorption, nitrogen production, desorption, and purge cycles are repeated continuously. Multiple vessels are typically incorporated in the PSA nitrogen generator, alternating between different stages to ensure a continuous supply of high-purity nitrogen gas.

By leveraging the selective adsorption properties of the CMS material and employing well-timed cycles of adsorption, desorption, and purging, the PSA nitrogen generator reliably produces a continuous stream of nitrogen gas with high purity levels.

Ten common questions about nitrogen generators

1.What purity of nitrogen gas can a nitrogen generator produce?

A nitrogen generator can produce nitrogen gas of various purities, ranging from standard industrial-grade nitrogen (typically 95% to 99% purity) to high-purity nitrogen (usually exceeding 99.9%), and even ultra-high purity nitrogen (typically exceeding 99.999%). The choice of purity depends on specific application requirements.

2.What is the working principle of a nitrogen generator?

The working principle of a nitrogen generator is primarily based on either the adsorption technology using molecular sieves or membrane separation technology. Adsorption technology selectively adsorbs oxygen and moisture using a specific adsorbent material, such as molecular sieves, while allowing nitrogen to pass through. Membrane separation technology, on the other hand, utilizes the size and permeability of gas molecules to achieve the separation of nitrogen from other gas components on a membrane.

3.What inputs does a nitrogen generator require, and how does it operate?

• To operate a nitrogen generator, it typically relies on air as its input source. The process begins by compressing the air using an air compressor. The compressed air is then directed through an adsorber that contains molecular sieves or a membrane separator within the nitrogen generator. These components selectively remove other gases, allowing pure nitrogen to be obtained as the final output.
• In some cases, certain nitrogen generators may require an electrical power supply to facilitate the compression and separation processes. This power supply ensures the efficient operation of the air compressor and enables the molecular sieves or membrane separator to function effectively.
• A nitrogen generator harnesses the input of air, subjecting it to compression and employing specialized gas separation components, enabling the reliable production of pure nitrogen as the desired output. In this process, air is first compressed using an air compressor, and then directed through molecular sieves or a membrane separator within the nitrogen generator. These components selectively remove other gases, allowing for the extraction of pure nitrogen.
• In certain cases, an electrical power supply is required to facilitate the smooth operation of the nitrogen generator throughout the nitrogen production process. This power supply ensures the efficient functioning of the air compressor and enables the molecular sieves or membrane separator to effectively carry out the gas separation process.

• By incorporating these critical steps and components, a nitrogen generator ensures a consistent and reliable supply of pure nitrogen. It caters to the specific needs and requirements of various applications, providing a continuous source of nitrogen gas.
• The inclusion of an electrical power supply, when required, plays a crucial role in maintaining the uninterrupted operation of the nitrogen generator. It ensures that the air compressor receives the necessary power to compress the air, which is then passed through the molecular sieves or membrane separator for the separation of nitrogen from other gases. This reliable power supply guarantees a continuous and reliable nitrogen production process, meeting the demands of the application.
• The electrical power supply is an essential aspect of the nitrogen generator's infrastructure, enabling the smooth and efficient operation of the entire system. By ensuring uninterrupted power availability, businesses can rely on a consistent supply of pure nitrogen, enhancing productivity, and supporting various industrial processes.

4.How is a nitrogen generator different from nitrogen supply in gas cylinders?

The main difference between a nitrogen generator and nitrogen supply in gas cylinders lies in the mode of nitrogen supply. A nitrogen generator continuously extracts nitrogen from the air, providing a continuous nitrogen supply without the need for cylinder replacements. In contrast, nitrogen supply in gas cylinders requires periodic cylinder replacements, and the supply quantity is limited by the cylinder capacity.

5.What should be considered for the maintenance of a nitrogen generator?

The maintenance of a nitrogen generator typically involves regular cleaning and replacement of the adsorber with molecular sieves or membrane separator, inspection and maintenance of the compressed air system, monitoring nitrogen generation performance, etc. Specific maintenance requirements should be referred to the user manual or guidance provided by the manufacturer of the nitrogen generator.

6.Which industries are nitrogen generators suitable for?

Nitrogen generators are widely used in various industries, including industrial, medical, food and beverage, and laboratory applications. They are commonly used in industries such as chemicals, electronics, and metal processing. In the medical field, they are used for anesthesia and gas delivery. In the food and beverage industry, they are used for packaging and preservation. In laboratories, they are used for atmospheric control and protection of equipment.

7.What is the noise level of a nitrogen generator during operation?

The noise level of a nitrogen generator varies depending on the model and design. Generally, nitrogen generators have low noise levels, especially when compared to traditional compressed air systems. Specific noise levels can be referred to the technical specifications or noise test reports of the nitrogen generator.

8.How long does it take for a nitrogen generator to start producing nitrogen gas?

The startup time of a nitrogen generator depends on the model and specifications. In general, nitrogen generators have short startup times, typically ranging from a few minutes to several tens of minutes. Larger capacity or higher purity requirement nitrogen generators may require longer startup times.

9.Can a nitrogen generator simultaneously produce nitrogen gas and oxygen gas?

The design purpose of a nitrogen generator is to separate oxygen and nitrogen to produce high-purity nitrogen gas. Therefore, in most cases, a nitrogen generator does not simultaneously produce nitrogen gas and oxygen gas. If simultaneous production of nitrogen and oxygen is required, additional equipment or techniques need to be used for further processing.

10.What is the energy consumption of a nitrogen generator?

The energy consumption of a nitrogen generator varies depending on the model, specifications, and operating conditions. Generally, nitrogen generators have relatively low energy consumption, especially when compared to traditional nitrogen supply in gas cylinders. Nitrogen generators are typically adjusted based on the actual nitrogen demand to improve energy efficiency and minimize energy consumption.
