3. Main Features for PSA Nitrogen Generator

• The raw material for nitrogen generation is ambient air sourced from nature. By supplying compressed air and power, nitrogen gas can be produced. The purity of nitrogen can be conveniently adjusted by regulating the supply of compressed air.

• The nitrogen generator is highly automated, allowing for quick gas production without the need for constant monitoring. It can operate unattended, and nitrogen gas can be generated within 10-15 minutes after starting up the equipment.

• The equipment itself has a straightforward process, requires minimal space, and consumes less energy, resulting in cost savings. To ensure the long-term usability of molecular sieves, they are filled using the snowstorm method, which prevents their pulverization caused by the impact of high-pressure airflow.

Carbon Molecular Sieve

Carbon Molecular Sieve,CMS)is a highly efficient adsorbent material utilized in nitrogen generators. It is known for its exceptional quality, high density, and compactness. The CMS is equipped with a spring-loaded mechanism that ensures balanced operation throughout and is protected by a dedicated pressure sensor.

For nitrogen purity levels below 99.99%, CMS-240 is commonly preferred. However, when aiming for a purity of 99.999% in a single step, CMS-260 is the recommended choice. These carbon molecular sieves play a critical role in the nitrogen generation process, enabling the production of nitrogen gas with extremely high purity. They find applications in various industries, such as manufacturing, healthcare, and laboratory settings, where the need for pure nitrogen is paramount.

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 time it takes for a nitrogen generator to start up depends on its specific model, specifications, and the technology used for nitrogen production. Different nitrogen generation technologies, such as membrane separation, pressure swing adsorption (PSA), or cryogenic distillation, have varying startup requirements and times.
• Membrane-based nitrogen generators typically have faster startup times. They use selectively permeable membranes to separate nitrogen from other gases and can achieve operational purity levels within minutes. On the other hand, PSA nitrogen generators rely on adsorbent materials to selectively adsorb oxygen and impurities, requiring a regeneration cycle to achieve the desired purity. As a result, PSA nitrogen generators often have slightly longer startup times, typically ranging from 10 to 30 minutes.
• Startup times can also be affected by factors like ambient conditions, system design, and any additional pre-filtration or purification processes incorporated into the generator. Manufacturers usually provide specific startup time information in the product documentation or specifications, enabling users to choose a generator that meets their time requirements.
• In summary, the startup time of a nitrogen generator is influenced by its model, specifications, and the technology utilized for nitrogen production. While nitrogen generators generally have short startup times, larger capacity generators or those designed for higher purity requirements may require longer startup periods. Consulting the manufacturer's documentation will provide accurate information regarding the startup time of a particular nitrogen generator model.

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.
