CRYOGENIC CONSULTING SERVICE , argon PRODUCTIONA Technology Review Paper for Presentation at the 1999 Modern Air Separation Plant Technology ConferenceJuly 26 -- 27, 1999 at Chengdu, People's Republic of ChinaBy Joseph T. Bernstein, CRYOGENIC CONSULTING SERVICE Separation BackgroundThe major components of atmospheric air include nitrogen ( ), oxygen ( )and argon ( ). argon is produced as a byproduct of CRYOGENIC air separation forthe production of pure oxygen or pure oxygen and on whether product oxygen and nitrogen are low pressure gas or high-pressure gas or liquids, CRYOGENIC air separation processes may take various Low Pressure Cycle (Figure 1) utilizes air compressed to approximately 6 atma;heat exchange to cool air to near condensing temperature (utilizing cooling from productoxygen, nitrogen, etc.)
