2. Working Principles for PSA Nitrogen Generator

Pressure swing adsorption(PSA)nitrogen generator is an automatic equipment that uses air as material,use carbon molecular sieve as adsorbent, pressure reduction desorption principle to adsorb oxygen from the air, thereby separating nitrogen.

3. Main Features for PSA Nitrogen Generator

• Air, as a raw material, is sourced from the environment. By supplying compressed air and power, nitrogen can be produced. The purity of nitrogen can be conveniently adjusted by regulating the supply of compressed air.

• Our equipment is highly automated, ensuring fast gas production and the ability to operate without constant supervision. Nitrogen production can commence within just 10-15 minutes of startup.

• The equipment is designed with simplicity in mind, occupying minimal space while consuming minimal energy and incurring low costs.

• To preserve the integrity and longevity of the molecular sieves, we employ the snowstorm method for filling. This technique prevents the pulverization of molecular sieves that may occur due to the high-pressure impact of airflow. Consequently, the molecular sieves can be used continuously for an extended period.

• For ease of operation, we have incorporated an imported analyzer that allows for on-line inspection. This analyzer is user-friendly, requires minimal space, consumes low energy, and incurs minimal costs.

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?

• A nitrogen generator typically relies on ambient air as its input source. The process begins by compressing the air using an air compressor, which increases its pressure and prepares it for further treatment. The compressed air is then directed into the nitrogen generator, where it undergoes purification through either adsorption or membrane separation.
• In an adsorption-based nitrogen generator, the compressed air passes through an adsorber filled with a specialized adsorbent material, such as molecular sieves. This material selectively adsorbs oxygen, moisture, and other impurities, allowing nitrogen to pass through and emerge as the purified output gas.
• In a membrane-based nitrogen generator, the compressed air is guided through a membrane separator that contains membranes with specific pore sizes. These membranes enable the separation of nitrogen from oxygen and moisture based on molecular size and permeability. As a result, purified nitrogen is obtained as the final product.
• It's worth noting that some nitrogen generators may require an electrical power supply to operate the air compressor and support the purification process. This electrical power is typically sourced from a standard power outlet or integrated power system within the nitrogen generator.
• By utilizing ambient air, compressing it, and employing either adsorption or membrane separation technology, nitrogen generators offer a reliable and efficient solution for producing high-purity nitrogen gas in various industrial applications.

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.
