Description:
Compress air
Feed air is sucked in, filtered and compressed by filter and compressor.
Pre-cool air
To separate air into its components, it must first be liquefied at an extremely low temperature. The compressed air must be pre-cooled with chilled water firsty.
Purify air
Impurities like water vapour and carbon dioxide are removed from the air in molecular sieve adsorber.
Cool air
Gases making up air can be liquefied at very low temperatures, the purified air is cooled to approx. -175°C in the main heat exchanger. The cooling is achieved by means of internal heat exchange, where the flows of cold gas generated during the process cool the compressed air. Rapid reduction of the pressure then causes the compressed air to cool further, whereby it undergoes partial liquefaction. Now the air is ready for the fractionating column, where the actual separation takes place.
Separate air
Separation of air into pure oxygen and pure nitrogen is performed in two columns, the medium-pressure and the low-pressure columns. The difference in boiling point of the constituents is exploited for the separation process. Oxygen becomes a liquid at -183°C and nitrogen at -196°C. The continuous evaporation and condensation brought about by the intense exchange of matter and heat between the rising steam and the descending liquid produces pure nitrogen at the top of the low-pressure column and pure oxygen at the bottom. Argon is separated in additional columns and involves some extra steps in the process.
Withdrawal and storage
Gaseous oxygen and nitrogen are sent into pipes to users, e.g. steelworks. In liquid form, oxygen, nitrogen and argon are stored in tanks and transported to customers by road tankers.
