HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Nuzhuo Group provides a detailed analysis of the basic configuration and application prospects of high-purity nitrogen air separation units.

With the rapid development of cutting-edge technologies such as high-end manufacturing, electronic semiconductors, and new energy, high-purity industrial gases have become indispensable “blood” and “food.” High-purity nitrogen (typically nitrogen with a purity of ≥99.999%) plays a crucial role due to its inertness, non-toxicity, and relatively low cost. As a global leader in industrial gas solutions, Nuzhuo Group recently released a technical white paper detailing the basic configuration and core technologies of high-purity nitrogen air separation units, and providing an in-depth outlook on their broad application prospects.

I. Core Foundation: Analysis of the Basic Configuration of High-Purity Nitrogen Air Separation Units

Nuzhuo Group points out that a mature and reliable high-purity nitrogen air separation unit is not a simple combination of individual units, but rather a highly integrated, precision-controlled system. Its basic configuration primarily includes the following core modules:

Air Compression and Purification System (Front-End Processing):

1. Air Compressor: The “heart” of the system, responsible for compressing ambient air to the required pressure and providing power for subsequent separation. Screw or centrifugal compressors are typically selected based on scale.

2. Air Pre-Cooling System: This system reduces the temperature of the compressed, high-temperature air, reducing the subsequent purification load.

3. Air Purification System (ASP): The “kidney” of the system, using adsorbents such as molecular sieves to deeply remove impurities such as moisture, carbon dioxide, and hydrocarbons from the air. These impurities are key obstacles to subsequent distillation and obtaining high-purity products.

Air Separation System (Core Separation):

1. Fractionation Column System: This system includes the main heat exchanger, distillation columns (upper and lower columns), and a condenser/evaporator. This is the “brain” of the technology, utilizing the differences in the boiling points of the air components (primarily nitrogen, oxygen, and argon) to separate nitrogen and oxygen within the column through deep freezing and distillation. High-purity nitrogen is produced here.

Nitrogen Purification and Booster System (Back-end Refining):

1. High-Purity Nitrogen Purification Unit: For purity requirements of 99.999% and above, the nitrogen exiting the distillation tower requires further purification. Hydrodeoxygenation or carbon-based purification technologies are typically used to remove trace oxygen impurities, bringing purity to the ppb (parts per billion) level.

2. Nitrogen Booster: Compresses high-purity nitrogen to the user’s desired delivery pressure, meeting the pressure requirements of various application scenarios.

Intelligent Control System (Command Center):

1. DCS/PLC Control System: The “nerve center” of fully automated control, monitoring thousands of operating parameters in real time and automatically adjusting equipment operating status to ensure stable and reliable gas purity, pressure, and flow, while optimizing energy consumption.

Nuzhuo Group emphasizes that the advantages of its equipment lie in its selection of top-tier brands for each module, seamless integration, and optimized process packages based on years of experience. This significantly improves energy efficiency while ensuring purity and reliability, thereby reducing customers’ overall operating costs.

II. The Future Has Arrived: Application Prospects for High-Purity Nitrogen Air Separation Equipment

With global industrial upgrades and technological advancements, demand for high-purity nitrogen is rapidly expanding from traditional sectors to high-tech fields, and its application prospects are immense.

The Electronics and Semiconductor Industry (the patron saint of chip manufacturing):

This is the largest growth area for high-purity nitrogen. High-purity nitrogen is used as a shielding gas, purge gas, and carrier gas in hundreds of processes, including wafer fabrication, etching, chemical vapor deposition (CVD), and photoresist cleaning, preventing oxidation during production and guaranteeing chip yield. With the continuous shrinking of linewidths in third-generation semiconductors and integrated circuits, the requirements for nitrogen purity and stability will become increasingly stringent.

New Energy Lithium Battery Manufacturing (Securing the “Source of Power”):

In key steps such as electrode fabrication, liquid filling, and packaging in lithium-ion batteries, the oxygen-free, dry environment created by high-purity nitrogen is crucial. It effectively prevents the reaction of the negative electrode material with oxygen and moisture, significantly improving battery safety, consistency, and lifespan. The global trend toward electrification has created enormous market opportunities for high-purity nitrogen equipment.

High-end Chemicals and New Materials (A Companion to “Precision Synthesis”):

In synthetic fibers, fine chemicals, and new aerospace materials (such as carbon fiber), high-purity nitrogen serves as a protective gas and atmosphere source, ensuring controllable chemical reactions and stable product quality.

Pharmaceuticals and Food Preservation (A Guardian of “Life and Health”):

In pharmaceutical production, it is used for aseptic packaging and antioxidant coatings; in the food industry, it is used in Modified Atmosphere Packaging (MAP), significantly extending shelf life. The demand for food-grade nitrogen continues to grow.

Nuzhuo Group’s Perspective:

In the future, the development of high-purity nitrogen air separation equipment will focus more on three major trends: intelligence, modularization, and miniaturization. These include achieving predictive maintenance and intelligent energy conservation through AI algorithms; shortening construction cycles through standardized modular design and flexibly adapting to different customer sizes; and developing miniaturized on-site nitrogen generation equipment to replace traditional cylinder gas and liquid nitrogen, providing customers with safer, more economical, and more convenient gas solutions.

Nuzhuo Group stated that it will continue to increase its R&D investment and is committed to providing global customers with full lifecycle services, from technical consulting, equipment customization, installation and commissioning, to long-term operations and maintenance. The Group will work with partners to promote industrial progress and create a more efficient and cleaner future.
