Air Separation Process
Cryogenic air separation process is one of the most popular air separation process used to
produce purified components of air, in particular oxygen, nitrogen, and argon. In
cryogenic gas processing various equipments like distillation column, heat exchanger,
cold inter connecting pipes are used at very low temperature. Hence all these equipments
must be well insulated. Process cycles are somewhat different depending upon how
many products are desired (either nitrogen or oxygen; oxygen and nitrogen; or nitrogen,
oxygen and argon); the required product purities; gaseous product delivery pressures; and
whether one or more products will be produced and stored in liquid form.
