Have you used a hydrogen emergency pressure relief valve in your installation? Share your experience
Emergency pressure relief has never been activated; the high-pressure safety valve has triggered erroneously, with 20 kilograms of pressure being released in 4 minutes
The circulating hydrogen compressor stopped operating due to a low oil station pressure interlock; it was started via emergency pressure relief at 0.7 Mpa/min, and the flare ignited with great intensity
Tested under nitrogen conditions~~~
Does the liquid level in the hydrogen circulation separator rise quickly? How is the liquid drained from the hydrogen circulation separator after venting?
I’ve used it before; the reaction temperature soared, and it was a real hassle – I broke into a cold sweat. It’s necessary to strictly control the liquid level in the tank to prevent it from entering the compressor or the flare line, as otherwise a flare could be generated. It is essential to follow the operating procedures strictly to ensure that the emergency pressure relief valve functions properly.
After pressure is released, the liquid level rises very quickly. Can you drain it fast enough? Once the liquid level exceeds a certain threshold, the press will enter interlock mode; moreover, the cooling system must not stop in case of overheating. I’m not sure how your company controls the liquid level in the tank – I would appreciate some advice
It hasn’t really increased much; the liquid cutting process isn’t affected
There is no good solution; the only option is to supply oil to the back as quickly as possible. Never let the circulating hydrogen liquid separation tank become full – relieve pressure first to ensure safety.
The cold high-pressure liquid level sensor failed, causing the liquid level in the recycle hydrogen buffer tank to rise sharply; pressure relief was activated
