Analysis of the causes of vibration in torch pipelines?
Thread Content
Our company is a methanol producer, and recently we have observed significant vibration in the flare pipeline as it enters the flare water seal tank Upon checking the liquid level in the flare water seal tank, the level is normal ； Level of the torch separation tank – the level is normal ； There is also no abnormally increased emissions.
Is there any vibration transmission? Is it caused by vibrations from other pipes?
1. Is there severe liquid accumulation at the lowest point of the torch pipeline network?
Call or write to the torch manufacturers for consultation; they have extensive experience. If necessary, ask them to send designers to provide on-site assistance, as safety is of utmost importance.
There is no vibration transmission; the pipelines ahead are all in good condition. There is no liquid in the drainage at the lowest point; it seems there is no accumulation of fluid either.
The design of the water seal outlet is unreasonable; discharge may occur in a pulsed manner, resulting in gas surge inside the water seal tube
Could it be that there is a problem with the torch tip molecules, resulting in pressure fluctuations in the torch emissions and thus vibrations?
The exact reason for not going to the site is not clear; it’s possible to check whether the foot bolts of the water seal tank and the secondary grouting are in good condition. One can also place an ear against the water seal tank to listen for any noises. Safety comes first – call the manufacturer and ask them to send someone to handle it
Is there a noise-damping design at the end of the air inlet of the water seal tank?
The vent volume is too large; ask the dispatch team to check the venting conditions at each station
For the water seal tank, it is necessary to check whether the overflow is normal? Check whether the water cut-off port of the water seal tank is unobstructed, as well as the condition of impurities inside the tank. Also, verify whether anti-surge measures have been taken on the pipelines within the inlet tank of the designed water seal tank High emission levels and high pressure can also cause pipeline vibration. If the vibration is severe, check whether the pipe supports and limits of the pipeline, as well as the sliding end of the water seal tank, have shifted.
