Explain fractional distillation of air in detail?
Dear student,
Fractional distillation of air: The liquid air coming out of the separator is passed through an expansion jet into the distillation column. Here, it is warmed slowly. Liquid nitrogen, having the lowest boiling point of –196°C, boils to form liquid nitrogen gas. This gas is collected from the upper part of the column. Argon, having a boiling point of –186°C, is collected next. Oxygen, having a higher boiling point of –183°C, is collected last.
By this way argon and oxygen gases are separated.
