can you tell me how this can be produce?
By the fractional distillation of liquid air, or by mechanical means using gaseous air.
Nitrogen
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption).
how are saturn's moon titan and neptune's triton similar Both of them are geologically active. who discovered the triton? William Lassell. when was it discovered? 10 October,1846. can you mention some physical characteristics of this natural satellite? Triton's crust consists of 55% nitrogen ice with other ices mixed in. Water ice comprises 15–35% and frozen carbon dioxide the remaining 10–20%. Its surface area is 23 million km. how is the atmosphere there? It has a tenuous nitrogen atmosphere, with trace amounts of carbon monoxide and small amounts of methane near its surface. can you tell me when was this first chemical element you just mentioned discovered? It has the symbol N and atomic number 7. where is this element can be found? From nitre (potassium nitrate, saltpetre) and sodanitre (sodium nitrate, Chilean saltpetre).

Nitrogen [SEP] Production
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk delivered nitrogen. Commercial nitrogen is often a byproduct of air-processing for industrial concentration of oxygen for steelmaking and other purposes. When supplied compressed in cylinders it is often called OFN (oxygen-free nitrogen). Commercial-grade nitrogen already contains at most 20 ppm oxygen, and specially purified grades containing at most 2 ppm oxygen and 10 ppm argon are also available.
