| Abstract: | This article describes several industrial applications of removing nitrogen as a kind of impurity, such as 02/N2 separation in air separation industry, methane concentration from coal bed gas and natural gas, deep removal of nitrogen from high purity gases, and nitrogen production process. PSA is the main technology in the nitrogen removal process. Natural and synthetic zeolites, modified zeolite （ ion exchanged and different Si / Al ratio modified ） , activated carbon , metal- organic compounds are used as adsorbents. |
