air separation unit process flow diagram

distillation has been practiced for over 100 years. Figure 1 is a basic flow diagram for the separation of air by cryogenic distillation. Air is compressed in the Main Air Compressor (MAC) to between 4 and 10 atm. It is then cooled to ambient temperature and passed through the Pre-Purification Unit (PPU).
