2. Working Principles for PSA Nitrogen Generator

A Pressure Swing Adsorption (PSA) nitrogen generator is an automated system that utilizes air as its raw material. By employing carbon molecular sieve as the adsorbent, it applies the principle of pressure reduction desorption to selectively adsorb oxygen from the air, resulting in the separation of nitrogen.

3. Main Features for PSA Nitrogen Generator

• The production of nitrogen involves utilizing ambient air as the raw material, which is readily available in nature. By supplying compressed air and power, nitrogen can be efficiently generated. The purity of nitrogen can be conveniently adjusted according to specific requirements by controlling the input of compressed air.

• The equipment used for nitrogen generation is highly automated, allowing for rapid gas production without the need for continuous monitoring. It can operate unattended and starts producing nitrogen within a short timeframe of 10-15 minutes after startup.

• The equipment itself is designed with simplicity in mind, occupying a small footprint, consuming minimal energy, and offering cost savings. Its streamlined process flow contributes to its compact size and energy efficiency.

• To ensure the durability and long-term use of the molecular sieves, they are filled using the snowstorm method. This technique prevents the pulverization of the molecular sieves caused by the impact of high-pressure airflow, safeguarding their performance and extending their lifespan.

• Regarding the online inspection of imported analyzers, they are characterized by their simplicity, high accessibility, small physical footprint, low energy consumption, and cost-effectiveness.

Ten common questions about nitrogen generators

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

• Nitrogen generators offer a versatile range of nitrogen purities, allowing users to tailor their nitrogen gas production to meet specific application requirements. The available purities span a spectrum, starting from standard industrial-grade nitrogen, typically ranging from 95% to 99% purity. This level of purity is suitable for many general industrial processes where nitrogen is used for inerting, blanketing, or as a carrier gas.
• For applications that demand higher purity levels, nitrogen generators can produce high-purity nitrogen exceeding 99.9% purity. This level of purity is often required in industries such as electronics, semiconductor manufacturing, and pharmaceuticals, where even trace amounts of impurities can adversely affect product quality or compromise sensitive equipment.
• In certain industries, such as electronics manufacturing or scientific research, ultra-high purity nitrogen is essential. Nitrogen generators can produce ultra-high purity nitrogen with purities surpassing 99.999%. Applications that benefit from ultra-high purity nitrogen include semiconductor fabrication, optical fiber production, and analytical instruments like gas chromatography-mass spectrometry.
• The choice of nitrogen purity depends on the specific application requirements, taking into account factors such as process sensitivity, desired product quality, and equipment specifications. Nitrogen generators offer the flexibility to adjust the nitrogen purity to precisely match these needs, ensuring reliable and efficient operation across a wide range of industries.

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?

A nitrogen generator typically requires air as the input source. When operating the nitrogen generator, air is compressed using an air compressor and then processed through the adsorber with molecular sieves or the membrane separator within the nitrogen generator. Finally, pure nitrogen is obtained as the output. Some nitrogen generators may also require an electrical power supply.

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.
