ASU Plant For Liquid Oxygen And Nitrogen

This ASU Plant for liquid oxygen and nitrogen can achieve low-pressure production, reducing the risks of storage and transportation.

This ASU Plant for liquid oxygen and nitrogen itself can produce a large amount of gas products under conditions close to normal pressure.

In contrast, many processes that require high-pressure gas need additional pressurization if prepared by other methods, which brings more safety risks.

Meanwhile, the liquid products it produces are stored under normal or low pressure, which is safer and more controllable in terms of risk than high-pressure gas cylinder storage and transportation.

Advanced Liquefaction Cycle for Maximum Yield

Nuzhuo's Liquid ASU is engineered for high-density energy storage and gas distribution. The core of the plant is our proprietary Cryogenic Liquefier, which utilizes a sophisticated refrigeration cycle:

Expansion Technology: High-efficiency turbo-expanders provide the necessary cooling capacity, optimizing the Joule-Thomson effect for air liquefaction.

Liquefaction Efficiency: Our plants are designed to minimize the "Specific Power for Liquefaction" (kWh/kg), ensuring that the conversion of gaseous air to liquid state is achieved with minimal thermal loss.

Recirculation Cooling: A closed-loop nitrogen expansion cycle is often employed to boost liquid oxygen (LOX) and liquid nitrogen (LIN) production rates simultaneously.

Integrated Vacuum-Insulated Storage                

• To ensure a complete "Production-to-Storage" workflow, Nuzhuo provides matched Cryogenic Liquid Storage Tanks
• Insulation Performance: Dual-layer vacuum powder insulation or high-vacuum multi-layer insulation to maintain liquid temperatures below -180°C.
• Custom Capacities: Storage solutions ranging from 5m³ to 500m³, designed according to ASME or GB standards.
• Zero-Loss Strategy: Integrated pressure-building systems and high-quality cryogenic valves minimize "Boil-Off Gas" (BOG) during long-term storage.
