With the help of a flow diagram, show the process of obtaining different gases from air. If the boiling points of Oxygen, Argon and Nitrogen are −183 C,-186 C and -196 C, which gas forms the liquid first as the air is cooled.
Dear student,
As we know that, air is the mixture of many gasses but nitrogen, oxygen, carbon dioxide, argon are the major components. So we can extracted these gasses from the air at the large scale.After liquefication of air by repeated compression and cooling; nitrogen, oxygen, carbon dioxide and argon are extracted using fractional distillation.
Liquid nitrogen has boiling point equal to -190 degree celcius and this turns into gas first and seperated from air.
the boiling point of argon is -183 degree celcius, thus it is collected after the extraction of argon.
Carbon dioxide turns into solid at a temp of -97 degree celcius , therefore, it is removed while air is put under liquefaction.
Hope this information will clear your doubts about topic.
