The liquid level issue in the torch cylinder
Thread Content
Our company’s torch cylinder is equipped with a level gauge, and the liquid level is determined by the condensation of steam. Sometimes the liquid level can reach 80% or even 90%, and manual drainage is required frequently, especially in winter. What I want to know is, does this liquid level need to be maintained? Can the drain valve be left on constantly?
Is it a torch cylinder or a liquid separation tank? The tank is not equipped with a level gauge; otherwise, the liquid level would reach 80% or even 90%, and the liquid would then flood the flare tower. There is liquid in the separation tank; it’s liquid carried along with the gas emitted by the flare. The steam condensate cannot enter the separation tank.
It’s the torch cylinder; indeed, our product has a liquid level indicator, but this level is designed for only a small section at the bottom, not for the entire torch. . . I don’t know what purpose this liquid level serves; the only thing I can think of is that it might prevent the waste materials that need to be discharged urgently from flowing downward, thereby avoiding potential safety hazards or accidents.
Where is your separation tank? Is it right below the torch cylinder?
The liquid separation tank is located in the pipeline upstream of the flare; after exiting the liquid separation tank, the fluid goes to the water seal tank before being sent to the flare.
The connection between the flare discharge pipeline and the flare vessel is at a certain angle to ensure that the flared gas is discharged without any liquid. The steam used in the torch serves to reduce smoke formation during combustion at the tip of the torch; its amount is very small. By the time the torch is burning, the steam has already vaporized, so it cannot condense and flow back to the bottom of the torch cylinder. As for the situation at your company, it’s indeed hard to explain. More information can be provided for everyone to help with the analysis.
