In the production of liquid nitrogen, then we don't need to find raw materials where necessary, because existing common nitrogen in the air we breathe, we just plain air is used, remove the main production through the production of liquid nitrogen is to reduce the temperature of raw material that is used in addition to the air.Sodium hydroxide (NaOH) for CO2 gas extraction alumina and power (AI2O3) for moisture to dry air. By default, the first step from the compressed air, high density by using vacuum air into the system, then the compressed air flows through. Sodium hydroxide (NaOH) for the removal of carbon dioxide (CO2), which we can write a chemical equation whether CO2 + 2NaOH + H2O = NaCO3 then air is extracted, remove carbon dioxide, will remove the parchment with oil to separate out the water first and then followed by a description.Remove the moisture to Make the dry with the use of a desiccant. Alumina (AL2O3), adaptors, which after passing this stage compressed air into the system, it's just nitrogen with oxygen, and then came the most important process in which we will need to remove the remaining oxygen gas separation with different nitrogen. We can do this by making it into the liquid oxygen, which can be made from a gas to a liquid, by reducing the temperature to a lower, we will use this method to extract the gas from the methodology of become liquid heterogeneous gas temperature is not.Are equal. Dissolved oxygen becomes a liquid temperature of about – level before 183 degrees Celsius. "We have to be able to separate out the oxygen from nitrogen to remove all. It then continues to decrease the temperature to change from gas to liquid nitrogen is liquid nitrogen which is made in low temperature – 196° c.
