Study Notes
Oxygen Production
- Large volumes of oxygen are primarily produced through fractional distillation of air.
Fractional Distillation of Air
- Distillation occurs in the process of producing oxygen through fractional distillation of air at very low temperatures, typically around -200°C.
- In the 4th stage of air compression, oxygen and nitrogen are separated from other gases.
Oxygen Concentrators
- Oxygen concentrators are primarily used to produce oxygen for medical purposes, such as for patients requiring oxygen therapy.
- The primary purpose of oxygen concentrators is to produce oxygen-rich air for patients.
- Molecular sieves, composed of a zeolite-based material, are used in oxygen concentrators.
- The primary function of molecular sieves is to selectively separate nitrogen and oxygen molecules, allowing oxygen to pass through and nitrogen to be absorbed.
- Oxygen concentrators provide approximately 85-93% oxygen concentration at a flow rate of 0.5-5 liters per minute.
Distillation Process
- Nitrogen boils off first during the distillation process of air to produce oxygen.
