Complete Set PSA Nitrogen System Solution/ Psa Nitrogen Gas Plant For Medical Industry

Description of 99.999% Purity 30Nm3/H PSA Nitrogen Generator Applicable to medical industry

A Pressure Swing Adsorption (PSA) nitrogen generator is a sophisticated automated device that is specifically designed to produce nitrogen gas with a high level of purity. This generator utilizes the surrounding air as the primary raw material and employs a carbon molecular sieve as an adsorbent. The principle of pressure reduction desorption is utilized to selectively capture oxygen molecules from the air, effectively separating nitrogen.

Within the PSA nitrogen generator, the air is directed through a bed of carbon molecular sieve under high pressure. The carbon molecular sieve possesses a greater affinity for oxygen molecules, causing them to be adsorbed while allowing nitrogen molecules to pass through. By adjusting the pressure, the adsorbed oxygen molecules are released, leaving behind nitrogen gas that is pure and devoid of impurities.

This process empowers the nitrogen generator to produce nitrogen gas of the desired purity levels, catering to diverse industries and applications. It provides a dependable and cost-effective solution to fulfill the demand for high-purity nitrogen gas.

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 generate nitrogen gas, a nitrogen generator typically relies on air as its input source. The process begins with the air being compressed using an air compressor, which increases its pressure. The compressed air is then directed into the nitrogen generator, where it undergoes further processing.Within the nitrogen generator, there are two common methods for separating nitrogen from other components: adsorption with molecular sieves or membrane separation. In the adsorption process, the compressed air is passed through an adsorber containing molecular sieves. These sieves have the ability to selectively adsorb oxygen and moisture, allowing nitrogen to pass through and be collected as the desired output.Alternatively, in membrane separation, the compressed air is directed to a specialized membrane within the nitrogen generator. This membrane is designed to have microscopic pores that enable the smaller nitrogen molecules to pass through, while blocking larger molecules like oxygen. By applying pressure, nitrogen gas is forced through the membrane, resulting in the separation and collection of pure nitrogen.It's worth noting that some nitrogen generators may require an electrical power supply to operate certain components, such as the air compressor or control systems. This ensures the nitrogen generator functions optimally and maintains a steady supply of nitrogen gas.

Overall, a nitrogen generator utilizes the compression of air, followed by either adsorption or membrane separation techniques, to produce pure nitrogen gas as the final output. The specific method employed depends on the design and capabilities of the nitrogen generator.

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.
