PSA Nitrogen Generator for Chemical Industry 95-99.99% Purity

BROTIE PSA Nitrogen Generator: Precision On-Site N₂ for Industrial Demands

Unlock a reliable, cost-effective, and on-demand source of high-purity nitrogen with BROTIE's Pressure Swing Adsorption (PSA) Nitrogen Generators. Leveraging advanced Carbon Molecular Sieve (CMS) technology, our systems deliver the purity your chemical and industrial processes demand, eliminating the logistical hassles and recurring costs of delivered liquid or cylinder nitrogen.

Core Features & Advantages:

1. Advanced CMS Technology: The heart of our generators is the high-quality Carbon Molecular Sieve sorbent. Its unique pore structure selectively adsorbs oxygen (O₂), moisture, and CO₂ molecules at high pressure, allowing nitrogen (N₂) to pass through efficiently. This forms the foundation for reliable gas separation.
2. Automated PSA Process: Controlled by a robust Programmable Logic Controller (PLC), pneumatic valves precisely alternate between twin adsorption towers. While one tower adsorbs impurities under pressure, the other regenerates by depressurizing and purging. This continuous cycle ensures a steady, uninterrupted flow of nitrogen.
3. High Purity & Flexibility: Generate nitrogen with precision, ranging from standard industrial grades (95%) to ultra-high purity levels (up to 99.99%). Easily adjust the purity setpoint via the PLC to match your specific application requirement (FAQ: How do I adjust purity?).
4. Integrated System Design: BROTIE provides comprehensive solutions:
   • Essential Components: Includes air compressor, refrigerant air dryer & filters, main PSA generator, air buffer tank, and nitrogen buffer tank.
   • Pressure Boost Option: Need nitrogen at higher pressures? Our oil-free nitrogen compressors seamlessly integrate to boost the generator output (typically 6 barg) to your required pressure (up to 40 barg or more).
   • Optimized Stability: Air buffer tanks ensure smooth compressed air supply, reducing compressor cycling. Nitrogen buffer tanks guarantee consistent downstream delivery pressure and flow.
5. Significant Operational Advantages:
   • Cost Reduction: Drastically lower your nitrogen costs compared to delivered liquid or cylinders, especially for high-volume users. Payback periods are often rapid.
   • On-Demand Supply: Eliminate dependence on suppliers, delivery schedules, and potential stock-outs. Produce nitrogen exactly when and where you need it, 24/7.
   • Enhanced Safety: Remove the risks associated with handling high-pressure cylinders or cryogenic liquids.
   • Low Maintenance & Automation: PLC automation ensures smooth operation with minimal manual intervention. CMS has a long lifespan with proper air prep.
   • Energy Efficient: Modern PSA designs optimize compressed air consumption and regeneration cycles, reducing operating costs.
   • Scalability: Systems are available from compact 3 Nm³/h units up to large 2000 Nm³/h industrial plants (See Key Specifications below).

Frequently Asked Questions (FAQ):

• Q: How does the PSA technology work? A: Compressed, clean air enters a tower filled with CMS. Under pressure, the CMS adsorbs oxygen, water vapor, and CO₂ molecules faster than nitrogen, allowing concentrated N₂ to exit. Simultaneously, the second tower depressurizes (desorbs) the captured gases to vent, regenerating the CMS. PLC-controlled valves automatically switch towers to ensure continuous flow.
• Q: Can I get higher pressure nitrogen? A: Absolutely. While the standard PSA generator typically outputs N₂ around 6 barg, BROTIE integrates specialized oil-free nitrogen boosters (compressors) after the generator to elevate pressure precisely to your process requirement (e.g., 10 barg, 40 barg+).
• Q: How do I adjust the nitrogen purity? A: Purity is primarily adjusted via the PLC control system. Increasing purity usually involves modifying adsorption times or purge settings, often resulting in a slight decrease in maximum flow rate. Our systems are designed for easy adjustment within their rated range.
• Q: What air prep is required? A: Clean, dry compressed air is vital for CMS longevity and performance. Our integrated packages always include a refrigerant dryer and coalescing/fine filters to remove oil, water aerosols, and particulates to the required level (typically Class 3.1.1 or better). The air buffer tank also helps stabilize supply.
• Q: What material options are available? A: Standard construction uses carbon steel for tanks and vessels. For applications requiring enhanced corrosion resistance or oxygen-sensitive processes (like food/pharma), key components (adsorber vessels, piping, buffer tanks) can be constructed from Stainless Steel 304.
