How Nitrogen Element Is Made

The prime of air component is nitrogen gas, N₂­­, (78,08% from volume). Nitrogen compound on the earth is very few, the biggest compound is NaNO in Chili and Peru. It means the resources of N₂ in nature are atmosphere.

The Nitrogen element make from atmosphere with the distillation of liquid air. The distillation of liquid air become component’s it make by stage distillation.

Process of distillation stage by air it’s, put the clean air on compressor. Next, freeze the clean air with freezer. The freeze condenses by mean of space and the product is a freeze airs with result that liquid air. After that, we filter liquid air for separate CO₂ and hydrocarbon. Furthermore distillate it. Enter the liquid air on top of nitrogen column. Component that easy to evaporate, turn out to be gas. In middle column, argon turn out and liquid oxygen. Oxygen as air component is very hard to evaporate and assemble in base. The normal point boil of nitrogen, argon, and, oxygen are -195,8­­­^oC, -185,7^o C, and -183,0^o C
