What is the most cost efficient way to produce nitrogen?

Answer 1

If you want to use or transport it in liquid form, liquefaction of air. Otherwise, it depends on what materials are readily available and what other chemical operations are taking place that might produce it as a byproduct.

Answer 2

Roughly 78% of the air around us is Nitrogen. That means you already have it free. The only thing that is not free is the process of isolating it from the rest of the air - hence your question - cost effective!

There is a process called seiving - i.e. use sieves for filtering out what you dont want. Air is first compressed by means of a compressor and forced into a chamber containing Carbon Molecular Sieves (CMS). The sieves allow only Nitrogen molecules to pass through. This is collected and stored in cylinders or pressure vessels. For small quantities, this is a cost effective, provided electric supply is cheap in your area.

Another method is by using a huge column of progressive cooling and liquefication of gaes. Various gases liquify at various temperatures.

Answer 3

For very large quantities, from the air using liquification. For small quantities you can actually buy systems that use molecular sieves to "filter" it from the air.

Answer 4

Molecular sieves

Answer 5

cryogenic pumps, and cryogenic distillation allowing the nitrogen to boil off, leaving the other lesser gasses in liquid state. and if needed to be recondensed into liquid, recompressed in another set of pumps and condenser.

Answer 6

Exhale.

Answer 7

pass wind

Answer 8

why what are you going to blow up?
