Heat exchangers are used to cool a substance; I know that water can be used as a cooling medium, but can nitrogen be used as well?

Nitrogen is generally not chosen – what are the considerations?

Why use nitrogen? Nitrogen? Nitrogen? Haven’t heard of it
After cryogenic treatment, I wonder if this gaseified portion can be recovered and used as a cooling source. Replace part of the circulating water
If the heat exchanger is not replaced, the cost is very low. It’s just the cost of the pipelines, but it saves on recycled water.
Sure, but you need to calculate it carefully.
Is the cooling agent nitrogen or liquid nitrogen? This difference has a significant impact on the cost of the heat exchanger itself.
Nitrogen is an asphyxiant gas; there is a risk in case of a leak! You can use chilled water.
Low-temperature nitrogen can certainly also be used for heat recovery, either to cool circulating water, air-conditioning water, or for ventilation purposes. It comes down to the quality of the cooling source and the cost-effectiveness of the investment.
