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

• A nitrogen generator utilizes ambient air, sourced from nature, as the raw material for nitrogen production. By supplying compressed air and power, nitrogen gas can be generated. The purity of nitrogen can be conveniently adjusted by regulating the supply of compressed air.

• The nitrogen generator is characterized by its high level of automation, enabling rapid gas production without the need for constant supervision. It can operate unattended, and nitrogen gas can be generated within a short period of 10-15 minutes after starting up the equipment.

• The equipment itself is designed with a straightforward process, requiring minimal space and consuming less energy, which leads to cost savings. To ensure the long-term durability of the molecular sieves, the snowstorm method is employed during their filling. This method prevents the pulverization of the molecular sieves caused by the impact of high-pressure airflow.

• For efficient monitoring, the nitrogen generator is equipped with an imported analyzer that facilitates online inspections. This analyzer has excellent accessibility, occupies a small area, and contributes to energy and cost efficiency.

  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 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 main purpose of a nitrogen generator is to separate oxygen and nitrogen from an air source to produce nitrogen gas of high purity. Nitrogen generators are specifically designed to exclusively generate nitrogen gas and do not simultaneously produce oxygen gas under normal circumstances.
  • The separation process in a nitrogen generator relies on technologies such as membrane separation, pressure swing adsorption (PSA), or cryogenic distillation. These methods selectively remove oxygen and other impurities from the air, leaving behind pure nitrogen gas as the desired output.
  • If there is a need for simultaneous production of nitrogen and oxygen gases, additional equipment or alternative techniques must be employed. Some industrial processes or medical applications may require both gases to be produced together. In such cases, specialized systems like air separation units (ASUs) or oxygen concentrators can be used. These systems employ more complex and energy-intensive processes to achieve the simultaneous production of nitrogen and oxygen gases.
  • It is crucial to note that most nitrogen generators are designed solely for the production of nitrogen gas. They are optimized for the separation of oxygen and nitrogen to generate high-purity nitrogen. Simultaneous production of nitrogen and oxygen is not a standard feature of nitrogen generators.
  • However, in cases where the co-production of nitrogen and oxygen is necessary, specific equipment and techniques can be employed. Additional systems, such as air separation units (ASUs) or oxygen concentrators, are available for such applications. These specialized setups utilize more complex processes and technologies to facilitate the simultaneous generation of nitrogen and oxygen gases.
  • To summarize, the primary objective of a nitrogen generator is to separate oxygen and nitrogen to produce nitrogen gas of high purity. While nitrogen generators are not typically designed to simultaneously generate nitrogen and oxygen, alternative equipment and techniques exist to accommodate applications that require the co-production of both gases.

   

  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.
