Working Principle of Cryogenic Nitrogen Oxygen Separation
Cryogenic Nitrogen Oxygen Separation integrates low-pressure flow into air separation units, reducing air separation energy consumption and enhancing operational safety. For process calculation and unit equipment design, specialized chemical engineering software is used for distillation and structural calculations, ensuring advanced and reliable equipment.
To adapt to market needs, beyond producing conventional external-compression air separation plants, the company has created internal-compression air separation processes, decreasing installation work and maintenance for integrated systems.
Furthermore, a skid-mounted purification system is designed to minimize the duration of on-site piping installation.

Separation Processes
• Single-tower: Focuses on single-product output (N₂ or O₂).
• Dual-tower: Enables co-extraction of O₂ and N₂.
• Multi-tower: Supports co-extraction of O₂, N₂, and Ar.
• Internal compression: Compresses product O₂/N₂ to target pressure via an in-cold-box pump.
• External compression: Compresses cold-box product gas (atmospheric pressure) to target pressure via a post-cold-box booster.
