ASU Technical Performace Parameter
Design case:
| Product | Output,Nm3/h | Purity % | Pressure at cold box outlet/Temperature Mpa/(℃) | Pressure at Battery outlet/Temperature Mpa/(℃) |
| Gaseous Oxygen | 28,000 | 99.6% O2 | 0.015/24.9 | 3.0/≤42 |
| Liquid Oxygen | 300 | 99.6% O2 | 0.15/-181.7 | - |
| Gaseous Nitrogen | 28,000 | ≤5ppm O2 | 0.007/24.9 | - |
| Liquid Nitrogen | 100 | ≤5ppm O2 | 0.2/-193 | - |
| Pressure Nitrogen | 600 | ≤5ppm O2 | 0.434/24.9 | As sealing gas for oxygen compressor |
| Liquid Argon | 1,000 | ≤5ppm O2+N2 | 0.16/-183.8 | |
Note: Nm3/h means at the condition of 0℃, 1.013bar(A)
Liquid product Nm3/h data refers its gaseous state transferred
-
Continuous operation period between two defrost≥2 years
-
Time required for defrost～36 hours
-
Time required for start-up (from the start-up of expander to attainment of oxygen purity)
～36 hours
-
The instrument air need to be provided by user during start-up, will be provided by ASU itself when running.
-
Utility Consumption List see next page.
Unit power consumption(without oxygen compression)0.384Kwh/Nm3 O2 ±4%
{28000+(300+100+1000)X3}/12365=0.384
Unit power consumption (with oxygen compression) 0.555Kwh/Nm3 O2 ±4%
{28000+(300+100+1000)X3}/17865=0.555
Note: -Power refers to shaft power as per primary design
- Liquid product output taken as 3 time gaseous output for calculation
- Electrical heaters for oil lubrication system, oil pumps and smoke fan motor for oxygen compressor as well as turbo expander are not included.
- Final figures depend on final design of the Air Separation plant and the compressors chosen after final design.
