Product Overview
The SINNA GAS Membrane Nitrogen Generator is an advanced on-site nitrogen production system designed for continuous industrial operation. It separates nitrogen (N₂) from compressed air using high-performance hollow fiber membrane separation technology, enabling stable, cost-efficient nitrogen supply directly at the point of use.
Compared with traditional nitrogen supply methods such as cylinders or liquid nitrogen delivery, the system eliminates logistics dependency and significantly reduces long-term operating costs.
The system is engineered for industries requiring medium-purity nitrogen (95%–99.5%), including oil & gas, chemical processing, food packaging, electronics manufacturing, and industrial safety applications.
SINNA GAS provides fully customized membrane nitrogen solutions optimized for energy efficiency, lifecycle cost reduction, and long-term operational stability.
Working Principle
The system operates based on the principle of selective gas permeation rates:
- Compressed air is first filtered and dried through a pre-treatment system
- Air enters the hollow fiber membrane bundle
- Oxygen (O₂), carbon dioxide (CO₂), and water vapor permeate rapidly through the membrane wall
- Nitrogen (N₂) molecules pass through more slowly and are collected as product gas
- Oxygen-enriched exhaust is safely discharged into the atmosphere
Key Engineering Principle
Gas separation is achieved through physical diffusion difference, not chemical reaction or adsorption.
This ensures:
- Stable long-term performance
- Continuous nitrogen output without cycling
- No chemical consumables or regeneration system required
