Discussion on pipelines for diesel hydrogenation heating furnaces
Thread Content
The feed to the heater of the diesel hydrogenation reactor enters the heater through two lines, and these two pipelines experience significant vibration. What is the cause of this?
The pressure, temperature, and flow rate values need to have their accuracy verified, as well as whether there have been any changes in the oil quality and any issues with the pumps. Wait
1. Problems with the pump, such as vacuum formation or cavitation. 2. Uneven flow distribution across the two sets of furnace tubes. 3. Coking in the furnace tubes or excessive pressure differences due to design issues. 4. Severe water content in the oil. 5. Uneven heating of the two sets of furnace tubes inside the furnace chamber; it is necessary to check the burner settings. This is just my personal opinion; I welcome corrections from the experts
Is this furnace a newly installed one or an old unit? Is this fault persistent or occasional? Please, the original poster, explain more in detail so that everyone can analyze it together.
It’s an old device; this fault has always been present.
1. The issue with the pump; if this problem persists, the chances are low. 2. Uneven flow distribution in the two furnace tubes, or internal coking leading to uneven flow. 3. Is the load exceeding the designed value?~~~ 4. The initial liquid removal was inadequate, resulting in water vapor in the oil; this caused significant vibration once it entered the furnace tubes. 5. Are the spring supports at the inlet and outlet in use? Check whether the fixing support is deformed and unable to provide support 6. Is the pressure drop of the reactor a bit high? Catalyst coking can also cause obstacles to the flow of oil into the reactor, resulting in excessive backpressure~~~
