atoms or molecules of gaseous substances are free to move relative to each other. The kinetic energy of atoms or molecules of a gaseous substance is relatively high and the gaseous form can be influenced by its volume, temperature and its pressure. The elements form a plurality of gas laws, and the three elements can influence each other;

nitrogen gas of the chemical formula N₂It is usually a colorless and odorless gas, and nitrogen is generally less dense than air. Nitrogen is the main component of air, and accounts for 78.08% (volume fraction) of the total amount of the atmosphere. When cooled to-195.8 deg.C under normal atmospheric pressure, the liquid becomes colorless liquid, and when cooled to-209.8 deg.C, the liquid nitrogen becomes snow-like solid. Nitrogen is chemically inert and hardly reacts with other substances at normal temperature, and is therefore often used for the production of preservatives. But can be chemically changed with some substances under the conditions of high temperature and high energy, and can be used for preparing new substances useful for human beings.

In the process of treating nitrogen as tail gas, the tail gas needs to be discharged after being combusted, but the discharge amount of the tail gas cannot be controlled, and meanwhile, the combusted gas cannot be subjected to secondary treatment, so that the nitrogen is directly discharged to the air to cause environment pollution.
