Product Overview
The SINNA GAS Containerized Membrane Nitrogen Plant is a fully integrated, skid-mounted industrial nitrogen generation system designed for continuous on-site production of nitrogen gas from compressed air using advanced hollow fiber membrane separation technology.
The system is engineered, manufactured, assembled, and tested at SINNA GAS factory and delivered as a complete plug-and-play nitrogen solution inside ISO container structure (20ft / 40ft optional).
It enables industries to eliminate dependence on liquid nitrogen delivery and cylinder supply, achieving stable, low-cost, and decentralized nitrogen production directly at the point of use.
Real Project Experience
SINNA GAS containerized nitrogen systems have been widely applied in:
- Oil refinery nitrogen blanketing systems (Middle East)
- Offshore platform inerting systems (Southeast Asia)
- Chemical storage tank protection projects
- Mining safety inert gas systems
- Food packaging nitrogen systems
Typical Project Performance:
- Continuous operation: 24/7 industrial duty cycle
- System uptime: >99% in field applications
- Reduced nitrogen supply cost: 40% – 70% compared with liquid nitrogen logistics
- Deployment time: 1–5 days after arrival
Why Global Industries Choose Containerized Nitrogen Systems
Traditional nitrogen supply methods suffer from structural limitations:
Liquid Nitrogen Supply:
- High logistics dependency
- Price fluctuation
- Transportation safety risks
Cylinder Supply:
- Frequent replacement required
- High manpower cost
- Interruptions in remote sites
SINNA GAS On-site Solution Advantage:
- Independent nitrogen generation on-site
- No logistics dependency
- Stable long-term operating cost
- Suitable for remote, offshore, and hazardous environments
- Fully automated operation with minimal manpower
Working Principle
The system uses hollow fiber membrane gas separation technology, a physical separation process based on gas diffusion rates.
Process Flow:
- Atmospheric air is compressed by air compressor
- Air passes through multi-stage filtration system
- Clean compressed air enters membrane modules
- Oxygen, CO₂, and water vapor permeate through fiber walls
- Nitrogen is retained and collected as product gas
- High-purity nitrogen is delivered to downstream applications
Technical Advantage:
- No chemical reaction
- No moving parts inside separation core
- No adsorbent material (unlike PSA systems)
- Extremely low maintenance requirement
- Stable performance under continuous load variation
