Manufacturing of oxygen

Manufacturing of oxygen

Air conditioner sodium hydroxide and silica are the row materials used.

Air is passed through air filter to remove dust and smoke.

Air is passed through concentrated sodium hydroxide solution to remove carbon dioxide gas.

Air is passed through silica jet to absorb water vapor carbon dioxide and water vapor are removed from air before it is liquified because they solidify and block the apparatus

The remaining components of air repeatedly at 200 atmospheres and allowed to cool down at -200 degrees Celsius to obtain liquid air,

Liquid air is fractionally distilled using a fractionating column.

Nitrogen boils off first because it has a lower boiling point of -196 degrees Celsius leaving behind oxygen with a higher boiling point of -183 degrees Celsius. Pure oxygen is then stored under pressure in steel cylinders.

Side effects and mitigation including, explosion of oxygen cylinders due to high pressure causing injury to people hence this can be mitigated by regular maintenance and monitoring of cylinders
