In modern industries, nitrogen, as an important inert gas, is widely used in many fields such as chemical industry, electronics, food, and medical care. With the advancement of technology, the types of nitrogen generators are becoming increasingly diverse. Among them, transformer adsorption technology and membrane separation technology are two common nitrogen -making methods. From the following technical characteristics, advantages, and applicable scenarios, the comparison of the advantages of pressure swing adsorption and membrane separation nitrogen generators.
pressure swing adsorption technology
Transformer adsorption technology is a method based on physical adsorption principles. This technology uses the selective adsorption characteristics of molecular sieve materials to different gas molecules to absorb oxygen and other impurities in the air under high pressure to relieve under low pressure to achieve nitrogen enrichment. The entire process is divided into two stages of adsorption and reconciliation, and the gas separation is completed through periodic pressure changes.
membrane separation technology
The diaphragm separation technology uses the difference between the semi -diaphragm to the different gas molecules to achieve gas separation. When compressed air is compressed through the membrane component, small molecular gas such as oxygen is more likely to pass through the membrane, and large -molecular gas such as nitrogen is cut, thereby achieving the enrichment of nitrogen. Membrane separation technology usually uses a multi -layer composite membrane to improve the separation efficiency.
Advantages of pressure swing adsorption nitrogen generator
1. Flexible regulation of nitrogen purity and output
The transformer adsorption nitrogen generator can easily adjust the purity and yield of nitrogen within a certain range by adjusting the adsorption time, adsorption pressure and other operating parameters. For example, in the process of industrial production that is not fixed for nitrogen purity, such as different stages of chemical synthesis, higher purity nitrogen may be required to protect raw materials in the early stage. The device can adapt to this change very well. Through simple parameter adjustment, different operating needs can be met without large -scale transformation of the equipment.
2. Adapt to the ability of raw material gas to change strong
It has a good adaptability for the quality and pressure fluctuations of raw materials. Even if the air intake pressure has a certain fluctuation, or the air contains a small amount of impurities, the transformer adsorption of nitrogen generator can still maintain relatively stable operation. Its adsorption agent can tolerate the existence of impurities to a certain extent, and can restore the adsorption performance through the regeneration process, which reduces the risk of equipment failure due to the gas problem of the raw material. Advantage.
Advantages of membrane separation nitrogen generator
1. The equipment structure is compact and the area is small
The core component of the membrane separated nitrogen generator is the membrane component, and its structure is relatively simple and compact. The entire device does not require a huge adsorption tower and other devices, so it covers a small area. This is a very critical advantage for some small factories, laboratories or maritime drilling platforms in the center of urban centers, such as small factories, laboratories, or maritime drilling platforms. In the clean workshop manufactured by electronic chips, space resources are valuable. The membrane separated nitrogen generator can be easily installed in a limited space to provide nitrogen protection for chip production without occupying too much workshop area, which is conducive to the layout of the workshop. Planning and efficient use of space.
2. Quickly start and produce gas quickly
The start time of the membrane isolated nitrogen generator is very short, and you can start producing qualified nitrogen in a few minutes. This is because the membrane separation process does not require complex adsorption and regeneration cycle like transformer adsorption. As long as there is air supply, the membrane component can immediately start to separate nitrogen. In some occasions that need to be temporarily or emergency use, such as nitrogen blowing during equipment repair, inert gas supply in emergency fire protection, the membrane separation nitrogen generator can respond quickly and provide the required nitrogen in time to avoid waiting for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen to wait for nitrogen. Time delay and production loss caused by supply.
Comparison of the advantages of pressure swing adsorption and membrane separation nitrogen generators needs to discuss different situations and different needs. Positive and effect.
Comparison of the advantages of pressure swing adsorption and membrane separation nitrogen generators. It has its own advantages and disadvantages. Choosing a suitable nitrogen method requires comprehensive consideration of factors such as purity requirements, production scale, and environmental impact. For enterprises with high purity nitrogen demand and large -scale production, PSA technology is a better choice; for occasions where small and medium -sized enterprises and nitrogen purity requirements are not high, membrane separation technology is more advantageous. Enterprises should choose the most suitable nitrogen -making solution according to their own actual situation to achieve a win -win situation for economic benefits and environmental protection.
