I’ve just started working at a chlor-alkali company, and I still don’t understand what compressed air is used for Our company has 30 cubic meters of nitrogen and instrument air – what are the uses of these? I hope the experts here can give me some advice! ! ! # ， ， &
Compressed nitrogen is generally used for system purging, to displace more hazardous and less dense gases within the system (such as hydrogen), and it can also be used as an air seal. Compressed air generally has two uses: one is as a power source for operating pneumatic valves in instruments ； Another use is as a process gas for tasks such as stirring, pneumatic drying, pneumatic conveying, and pneumatic milling.
Compressed air generally contains water. . It is used for purging or flushing pipes that generally have no requirements regarding moisture content; the sealing gas is dry compressed air, which is mainly used for gas sealing
Nitrogen protects the cathode system of the electrolyzer, preventing hydrogen from mixing with air and causing an explosion. More importantly, the cathode system must be filled with nitrogen after the electrolysis process is stopped. Instrument air is of course used for various automatic control instruments
Thank you all, haha. I’ve learned so much from this
Nitrogen is also used quite a lot for acetylene, especially after shutdown.
Compressed air is used for purging pipelines and mixing materials, nitrogen is used to displace gas in the system, and instrument air is supplied for instrument actuators.
