Mobile Nitrogen Generation Unit | On-Demand Portable N2

Process Description

    Air undergoes pressurization and filtration, preliminary cooling and initial dehydration, followed by deep dehydration via PPU. It then enters the cold box, where it is cooled to the dew point via the heat exchanger before entering the main distillation column for separation. The unseparated liquid air undergoes secondary distillation in the auxiliary column. The produced liquid nitrogen is pressurized by a liquid nitrogen pump and returned to the main column as reflux liquid. Finally, nitrogen is extracted from the top of the main column and reheated via the main heat exchanger before exiting the cold box.

·Manufacturing, Installation, and Commissioning Period:

Actual delivery period ≤7 months.

·Extraction Rate:

   Calculated based on air compressor exhaust flow: 12,500 Nm³/h, producing 7,000 Nm³/h. Actual operation: air compressor exhaust flow 13,300 Nm³/h, producing 7,600 Nm³/h. Extraction rate as high as 73%.

·Advantages:

   Utilizes dual-column dual-condenser process, and through years of experience, achieves extremely low resistance, reducing energy consumption. The entire unit features rapid and precise controllable load range adjustment, requiring minimal frequent operation over long periods, thereby reducing manual workload.

·Why It Is a Classic Case:

   This project achieved the transition from high labor intensity to low labor costs. This unit requires only one on-duty personnel, demonstrating our company's craftsmanship-level manufacturing capabilities.

·Additionally：Our company has successfully implemented one-click start/stop nitrogen generators, which operate stably and reliably. From pressing the one click start button to producing qualified nitrogen, it takes only 12 hours. However, the project scale is relatively small, being a single-column 1500 Nm³/h high-purity nitrogen unit.
