Demand analysis 

Air is a uniform multi-component gas mixture. Within 10km of the ground, its main components, such as nitrogen, oxygen and argon, are almost constant. In addition, there are small amounts of impurities, such as dust, CO2, water vapor, hydrocarbons such as SO2, CH4, C2H6, C3H8, etc. These components change with the environment. In addition, there are trace amounts of H2, ozone, N2O and so on. As the altitude increases, the amount of oxygen in the air decreases. Impurity content and altitude are the main factors to consider in the design.
