Air Separation into Oxygen, Nitrogen, and Argon

Unit 100 Figure 2 shows a PFD for the cryogenic distillation of air, Unit 100. This process was modeled after the Linde Double Column [1]. In the proposed design, a two-stage centrifugal compressor, with interstage cooling, is used to compress air to 9 atm. The air is then further cooled to 107 K in E-102 and E-103. Stream 7 is then sent to T ...
