Chemcad Air Separation Using Cyrogenic Distillation - Student

Chemcad Air Separation Using Cyrogenic Distillation - posted in Student: I am undertaking a design project and am new to using Chemcad. I am designing an air separation unit using cyrogenic distillation to produce the gases oxygen and nitrogen. I have researched many papers and it appears the air passes through a filter and a water separator before the molecular sieve. I have identified a unit

Air Separation Process : Cryogenic Distillation – ChemEng

CRYOGENIC SEPARATION. Cryogenic separation is distillation process occur at very cold temperatures. This process occurred at specific condition and distillation process requires two phase liquid and gas. This high purity of nitrogen can be achieved by using this process. The air will be compress until 10 bar then it will be cooling until it
