Leak in the water cooler of the ammonia synthesis unit
Thread Content
The water coolers used in the company’s ammonia synthesis process are of the U-type tube type. An exhaust valve is installed at the top of each cooler; when there is a leak in the cooler, this valve is opened. If water flows out in streams, then it is possible that gas could also emerge from the bottom drain valve in case of a leak, after all, the pressure of gas inside is high while the water pressure is very high as well
Reply to 1# xuyanhui198610: As a supplementary point, I think nitrogen, with a higher density, should be discharged from the bottom through backflow, while hydrogen, having a lower density than air, should be discharged through the exhaust valve at the top. I’m not sure if this understanding is correct
The water cooler used in the ammonia synthesis unit is leaking; gas can escape either from the bottom or from the top. Whether it is gas or liquid, it flows towards areas of lower pressure.
I’m not quite sure, OP – how is your water leaking to the higher end? Is it still your exhaust valve – is it exhausting coolant vapor or something else?
I agree with the view from floor 3; it has little to do with gas density
Isn’t there a safety valve, an explosion-proof plate, or something like that?
Generally, allowing high-pressure gas to flow within the pipe can easily cause the enclosure to explode; the system should be stopped immediately
Reply to 1# xuyanhui198610: The methanol water cooling system in our factory is made of ordinary carbon steel, and it leaks frequently. Sampling valves have been installed at the openings of the water cooling return pipes, but these valves don’t last more than a month before the pressure needs to be relieved and the leaks fixed; water cannot flow out from below
