Overview
The Small High Purity Cryogenic Nitrogen Plant is an advanced air separation system designed for continuous nitrogen production from atmospheric air. Using cryogenic rectification technology, the system separates nitrogen, oxygen, and argon at extremely low temperatures to achieve high purity nitrogen output.
This plant is suitable for industries requiring stable, large-scale, and ultra-high purity nitrogen supply.
Working Principle
The system operates based on the cryogenic air separation process:
- Air compression and purification
- Pre-cooling and moisture removal
- Cryogenic cooling via heat exchanger
- Rectification in distillation columns
- Nitrogen separation and storage
The final nitrogen purity can reach up to 99.999% (5N grade) depending on system configuration.
Key Features
- High purity nitrogen output up to 99.999%
- Stable continuous operation (24/7 industrial use)
- Low energy consumption per Nm³ nitrogen
- Fully automated PLC control system
- Long service life and high reliability
- Modular design for easy installation and expansion
- Suitable for large and medium-scale gas demand
Technical Parameters（技术参数）
- Nitrogen Purity: 95% – 99.999%
- Capacity Range: 50 – 5000 Nm³/h (customizable)
- Operating Pressure: 0.6 – 1.6 MPa
- Dew Point: ≤ -70°C
- Cooling Method: Cryogenic expansion refrigeration
- Control System: PLC + HMI automation
Applications
- Metallurgy and heat treatment
- Chemical industry
- Electronics manufacturing
- Food packaging and preservation
- Pharmaceutical industry
- Laser cutting and welding protection
- Oil & gas inerting systems
