Liquid level issues during the initial startup of the propylene cooler
Thread Content
The propylene cooler that was just put into use in our plant shows a liquid level of 70% as indicated by the control system, but the on-site level gauge (of the magnetic float type) experiences very large fluctuations in its reading! The worst part is: the level gauge is covered from bottom to top with a thick layer of frost! Can’t determine the liquid level? ! The big shrimps, please give some advice; the little fishes, come and make some bubbles haha
Please don’t let this post sink! ! 1
Where is the central control level measured from? .
The transmitter leads from the control room are basically the same as those of the local instruments! ! Hehe, so many problems indeed. We can now squat in front of the heat exchanger for 12 hours! ! There’s no good solution; I have to use a crude one
You can contact the instrumentation team to adjust the integral and derivative values of the level control valve, so that the level won’t fluctuate as much. Additionally, frost forming on glass sheets can be removed by using a nitrogen line to blow on the glass; firstly, the heat from nitrogen is used to melt the ice, and secondly, nitrogen drives away the water vapor in the air – without water, ice cannot form.
:victory: Agree with what was said upstairs! !
Use steam to smoke it – it’s the most convenient way, haha
