Modern industries require consistent nitrogen purity, cost-effective operation, and efficient equipment. However, choosing a suitable nitrogen making machine can be overwhelming without understanding its capabilities and compatibility.
What Is a Nitrogen Making Machine for Industrial Applications?
A nitrogen-making machine, or nitrogen generator, separates nitrogen from atmospheric air to deliver high-purity gas efficiently. It is widely used in food, pharmaceuticals, electronics, and oil industries, providing a reliable on-site nitrogen supply and reducing dependence on gas cylinders.
Understanding how a nitrogen generator works, its types, and how it benefits industrial operations will help you choose a suitable nitrogen generation system tailored to your specific application, saving cost and boosting efficiency.
How do you produce nitrogen?
Industrial nitrogen production involves extracting nitrogen from atmospheric air, which is composed of 78% nitrogen. The two most widely used technologies for this purpose are Pressure Swing Adsorption (PSA) and membrane separation. PSA nitrogen generators use carbon molecular sieves to adsorb oxygen, allowing nitrogen to pass through selectively. Membrane nitrogen generators rely on different gas permeation rates through polymer membranes to isolate nitrogen.
PSA systems are preferred when high-purity nitrogen (up to 99.9995%) is required. This process includes air compression, purification via filters and dryers, and passage through adsorption towers containing carbon molecular sieves. BODA GAS TECH’s BXN PSA nitrogen generator exemplifies this process with advantages like low energy consumption, customizable purity, and modular design.
Membrane nitrogen generators, such as BODA’s BMN series, are suitable for purity ranges up to 99.9% and feature compact structure, low maintenance, and energy efficiency. Both systems support continuous, on-site nitrogen production, which eliminates logistical delays and the recurring cost of gas cylinder refills.
Industrial Applications of Nitrogen Gas Production
The demand for nitrogen gas spans across numerous industries, each requiring specific purity and delivery rates. In the food and beverage sector, nitrogen is used for packaging to displace oxygen and extend shelf life. Pharmaceutical companies employ high-purity nitrogen for manufacturing and packaging processes to maintain sterile conditions. In the electronics and semiconductor industries, nitrogen is crucial in preventing oxidation during component production and assembly.
The petrochemical and oil industries use nitrogen in pipeline purging, blanketing storage tanks, and enhancing oil recovery. BODA GAS TECH’s nitrogen generators are deployed in these sectors, thanks to their ability to deliver customized flow rates and pressures. The metallurgical industry uses nitrogen to prevent oxidation in heat treatment and welding processes.
Because each application has distinct requirements, BODA GAS TECH provides stand-alone systems for indoor use, skid-mounted units for flexible setups, and containerized units suitable for outdoor or remote site operations. This versatility ensures the nitrogen generation system meets industrial standards while maintaining safety and reliability.
3 Common Types of Nitrogen Gas Production
1. PSA Nitrogen Generator
Pressure Swing Adsorption (PSA) is a widely adopted method for producing nitrogen with high purity levels ranging from 95% to 99.9995%. It uses carbon molecular sieves to adsorb oxygen from compressed air, allowing nitrogen to be isolated. PSA generators are ideal for industries needing a consistent supply of high-purity nitrogen. BODA GAS TECH’s PSA systems feature automated controls, energy-efficient operation, and optional remote monitoring, ensuring minimal maintenance and uninterrupted performance.
2. Membrane Nitrogen Generator
Membrane separation uses permeable fibers to differentiate gases based on molecular size and solubility. Nitrogen passes through the membrane more slowly than oxygen, water vapor, and other impurities, producing nitrogen of 95% to 99.9% purity. These generators are compact, quiet, and require minimal maintenance, making them perfect for decentralized production needs. BODA’s BMN models highlight simplicity and energy savings through customizable purity settings and consistent output.
3. Fractional Distillation Nitrogen Production
Fractional distillation is a highly effective method of generating nitrogen for industrial use. The process involves the supercooling of air to its liquefaction point and then distilling its component gases at their various boiling points. This process will yield nitrogen with a high purity, but is generally more costly than PSA or Membrane production.
