  • Technoeconomic analysis of oxygen-nitrogen separation

    2021-8-1 · For high purity gases, oxygen–nitrogen separation has been done using cryogenic distillation where the air is cooled down to a low temperature so that nitrogen condenses to liquid nitrogen. This process is known to produce high purity gas streams and is extensively used at large industrial scales (100–300 tons/day).
