How is nitrogen obtained from air
WebNitrogen and oxygen production. Oxygen and nitrogen represent main parts of the air. All N2 and O2 which are commercially available are produced form of the air. Nitrogen is colourless, odourless and tasteless gas. Atoms of the nitrogen have very strong bond which makes nitrogen very stable so it has no need to enter in chemical reactions. WebHow is nitrogen obtained? Fractional distillation of liquid air to produce nitrogen. In simple terms: a four-step process used: cooling, isolating nitrogen, separating from air, and then collecting. At the right low temperature, the nitrogen becomes a liquid and can then be extracted and harvested for industrial processes.
