Feasibility of using nitrogen for instrument air
Thread Content
Our company operates in a sector with very distinct peak and off-peak periods; during the off-peak times, there is a lot of idle time. We plan to shut down the air compressors and use nitrogen to feed into the instrument air pipeline in order to maintain basic operations. The company’s factories are generally open or semi-open; I’m not sure if there are any precedents in this regard? Or in other words, **are there any relevant safety standards?**
The nitrogen has not been purified and does not meet the requirements for instrument air.
It is acceptable if the purification parameters and pressure meet the requirements; generally, it is used temporarily when the pressure of the purification air is low. The cost of nitrogen is higher than that of purified air, and nitrogen poses a risk of suffocation.
Given the asphyxiation risk posed by nitrogen, it can only be used as a backup gas source and not for long-term use
The instrument air has been filtered of dust and oil; it will work for me for now, but I need to check whether the pressure is appropriate
How to control costs? That’s too extravagant!
It can be used as a backup or in emergency situations
Isn’t it less likely to pose a risk after long-term use? An experienced worker at the factory told me that it is not recommended to use nitrogen as instrument air for long periods of time
Air is so cheap; nitrogen is a bit expensive, I guess. How to store it,
