Working principle and process flow of PSA nitrogen generator

1, Basic knowledge

1. Gas knowledge

Nitrogen, as the most abundant gas in the air, is inexhaustible and inexhaustible. It is colorless, odorless, transparent, belongs to the sub inert gas category, and does not sustain life. High purity nitrogen is often used as a protective gas in places that isolate oxygen or air. The content of nitrogen (N2) in air is 78.084% (the volume composition of various gases in air is: N2: 78.084%, O2: 20.9476%, argon: 0.9364%, CO2: 0.0314%, other gases include H2, CH4, N2O, O3, SO2, NO2, etc., but the content is very small), molecular weight is 28, boiling point: -195.8 ℃, condensation point: -210 ℃.

2. Knowledge of stress

The pressure swing adsorption (PSA) nitrogen production process involves pressure adsorption and atmospheric desorption, and compressed air must be used. The optimal adsorption pressure of the currently used adsorbent - carbon molecular sieve is 0.75~0.9 MPa. The gas in the entire nitrogen production system is under pressure and has impact energy.

2, Working principle of PSA nitrogen production:

CMS pressure swing adsorption nitrogen generator is an automated equipment that uses carbon molecular sieves as adsorbents, and utilizes the principles of pressure adsorption and pressure reduction desorption to adsorb and release oxygen from the air, thereby separating nitrogen gas. Carbon molecular sieve is a cylindrical granular adsorbent made mainly from coal, processed through grinding, oxidation, shaping, carbonization, and special pore processing technology. Its surface and interior are filled with micropores, and it is black in color. The pore distribution is shown in the following figure:

The pore size distribution characteristics of carbon molecular sieves enable them to achieve dynamic separation of O2 and N2. This pore size distribution allows different gases to diffuse into the micropores of the molecular sieve at different rates without repelling any gas in the mixture (air). The separation effect of carbon molecular sieve on O2 and N2 is based on the slight difference in the kinetic diameter of these two gases. The kinetic diameter of O2 molecules is smaller, so they have a faster diffusion rate in the micropores of carbon molecular sieve, while the kinetic diameter of N2 molecules is larger, so the diffusion rate is slower. The diffusion of water and CO2 in compressed air is not much different from that of oxygen, while the diffusion of argon is slower. The final enriched gas from the adsorption tower is a mixture of N2 and Ar.

PSA Nitrogen Generator: Working Principle, Features, Advantages & FAQ

Product Overview

A Pressure Swing Adsorption (PSA) Nitrogen Generator is an advanced industrial system that extracts high-purity nitrogen from ambient air using carbon molecular sieves (CMS). By leveraging the kinetic separation of gas molecules under pressure, it delivers a continuous, on-demand supply of nitrogen, eliminating reliance on traditional cylinder or liquid nitrogen. Widely used in food packaging, electronics manufacturing, pharmaceuticals, and metal processing, this technology combines efficiency, cost-effectiveness, and environmental sustainability.

Key Features & Characteristics

Efficient Nitrogen Production
- Utilizes CMS with precise pore size distribution (0.3–0.5 nm) to separate O₂ (kinetic diameter: 0.346 nm) and N₂ (0.364 nm). O₂ diffuses faster into CMS pores under pressure, while N₂ is enriched and collected as product gas.
- Achieves nitrogen purity from 95% to 99.9995% (adjustable via process parameters).
Compact & Automated Design
- Modular structure with minimal footprint, suitable for on-site installation.
- PLC-controlled operation with touchscreen interface, enabling real-time monitoring of pressure, flow, and purity.
Energy Efficiency
- Low power consumption (typically 0.3–0.6 kWh/Nm³) due to short adsorption/desorption cycles (60–120 seconds).
- Optimized pressure swing cycle (0.75–0.9 MPa adsorption, atmospheric desorption) reduces energy waste.
Reliable Performance
- Dual-tower configuration ensures continuous nitrogen supply (no downtime during tower regeneration).
- High-quality CMS with long lifespan (5–8 years) and low maintenance requirements.

Frequently Asked Questions (FAQ)

1. How does a PSA Nitrogen Generator work?

The generator uses two adsorption towers filled with CMS. Compressed air enters the first tower, where O₂, CO₂, and moisture are adsorbed by CMS under pressure. Nitrogen exits as product gas. When the tower saturates, air switches to the second tower, while the first depressurizes to release adsorbed O₂ (regeneration). This cycle repeats continuously.

2. What is the typical purity range, and how is it adjusted?

Purity ranges from 95% to 99.9995%. Higher purity (e.g., 99.999%) is achieved by reducing nitrogen flow rate, allowing more time for O₂ adsorption. Lower purity (95–98%) prioritizes higher flow.

3. How much maintenance is required?

Daily: Check pressure gauges and filters.
Monthly: Replace air filters.
Annually: Inspect CMS and valves.
CMS lifespan: 5–8 years (depending on air quality and usage).

4. Is the generator suitable for small-scale applications?

Yes. Compact models (0.1–5 Nm³/h) are ideal for labs, food packaging, or electronics soldering. Larger systems (50–500 Nm³/h) serve industrial needs like oil & gas or metal heat treatment.

5. What are the installation requirements?

Requires a clean, dry environment with ambient temperature 5–40°C. Compressed air supply (oil-free, filtered) and electrical connection (220V/380V) are mandatory.
