NITROGEN SEPARATION AND PURIFICATION

In a cryogenic nitrogen production process the following steps occur  

which contains 78% Nitrogen, 21% Oxygen and 0.9% Argon, is fed to the process. 

Next the air enters an Oxidation Chamber that removes hydrocarbons by converting them to carbon dioxide (CO2) and water (H2O). 

The stream then passes through a water separator to remove most of the water. 

The process stream then enters a heat exchanger that a) cools the stream to -168°C and b) removes the CO2 and H20 as solids.
