Each train has a capacity of:
- High Pressure (29 bars) Gaseous Oxygen: 42,000 Nm3/hr
- Medium Pressure (10 bars) Gaseous Oxygen: 42,000 Nm3/hr
- Liquid Oxygen: 100 Nm3/hr
- Gaseous Nitrogen (10 bars): 12,000 Nm3/hr
- Liquid Nitrogen: 50 Nm3/hr
B) Compressed Air Plant:
This plant produces instrument and service air with following capacity:
- Instrument Air (10 bars): 22,000 Nm3/hr
- Service Air (10 bars): 8,500 Nm3/hr
