TAB ASU - Americas
SIAD’s comprehensive line of custom engineered and standard-design air separation plants produce high purity medical and industrial grade oxygen, nitrogen and argon by cryogenic distillation of atmospheric air. Our Air Separation Units are designed and built to the most rigorous engineering and manufacturing standards and incorporate SIAD’s technology developed from over 75 years of experience building cryogenic process equipment.
SIAD has delivered more than 600 ASU’s globally, supporting such industries as electronics, chemicals and petrochemicals, food and beverage, steel making, glass making, pulp and paper and industrial gases. Our product line includes:
- Custom Engineered Gas Plants
- Merchant Liquid Plants
- Nitrogen Gas Generators
- Oxygen/Nitrogen Liquefiers
ASU Production and Purity Range
| ASU PRODUCTION AND PURITY RANGE | ||
|---|---|---|
| Product and Flow Rates | Purity | |
| Oxygen | 500 to 110,000 Nm3/hr (17 to 3,800 mTPD) 19,020 to 4,1MM SCFH (18.7 to 4,200 sTPD) | up to 99.95% O2 |
| Nitrogen | 1,500 to 330,000 Nm3/hr (45 to 9,900 mTPD) 57,060 to 12,3MM SCFH (49.6 to 10,900 sTPD) | < 1 PPM O2 |
| Argon | Recovery: Up to 92% | < 1 PPM O2 < 1 PPM N2 |
scfh = 70 degrees F and 14.696 psi(a)
sTPD = Short Tons Per Day
Nm3/h = @ O degrees C and 1.013 bar (a)
TPD = Tons Per Day
