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 primary distinction between a nitrogen generator and nitrogen supply in gas cylinders lies in the mode of nitrogen provision. A nitrogen generator operates by continuously extracting nitrogen from the air, ensuring an uninterrupted and continuous supply of nitrogen without the need for cylinder replacements. In contrast, nitrogen supply in gas cylinders necessitates periodic cylinder replacements, and the quantity of nitrogen available is constrained by the capacity of the cylinders.
• With a nitrogen generator, the nitrogen production process is self-sustaining as it draws upon the surrounding air as its source. This eliminates the inconvenience of managing and replacing gas cylinders, providing a seamless and reliable nitrogen supply. The generator can adapt to varying demand levels, supplying nitrogen as needed without interruptions or delays.
• On the other hand, nitrogen supply through gas cylinders involves the use of pre-filled cylinders that contain a finite quantity of nitrogen. Once the nitrogen in a cylinder is depleted, it must be replaced with a new cylinder, which can be cumbersome and time-consuming. The available supply is limited by the volume of nitrogen contained within the cylinders, requiring careful monitoring and planning to ensure an uninterrupted nitrogen supply.
• When deciding between a nitrogen generator and nitrogen supply in gas cylinders, it is essential to carefully consider the unique requirements and preferences of the application at hand. Each option offers distinct advantages that can be tailored to specific needs.
• A nitrogen generator provides the significant advantage of continuous nitrogen production. It eliminates the hassle and cost associated with cylinder replacements, offering a reliable and uninterrupted nitrogen supply. This continuous nitrogen flow is particularly beneficial for applications that demand a constant and reliable source of nitrogen.
• On the other hand, nitrogen cylinders can be more suitable for applications with lower nitrogen consumption or situations where portability and space constraints are crucial factors. Gas cylinders provide a convenient and portable nitrogen source that can be easily transported and used in various locations. They offer flexibility and mobility, making them preferred options in scenarios where portability or limited space is a priority.
• The choice between a nitrogen generator and nitrogen cylinders depends on several factors, including the rate of nitrogen consumption, the need for a continuous supply, portability requirements, and available space. Carefully assessing these factors will help determine the most appropriate nitrogen supply solution for the specific application, ensuring efficient and reliable nitrogen provision while aligning with the unique needs of the operation.

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.
