Is a separation tank required before releasing the torch?
Thread Content
Our plant has a separation tank under the main flare, but the drainage pipeline often gets clogged during operation. Should we add another separation tank in front of the flare?
Reply to 1# zhlfwxx: A separation tank must be installed before the flare is used for gas-liquid separation. If liquid accumulates at the bottom of the flare, it will affect gas emission; moreover, moisture present in the gases being burned can also impact the ignition mechanism.
Before releasing the torch, it is necessary to use a separation tank for safety reasons. The original setup already includes such a tank, so there’s no need to add another one; it’s sufficient to get the existing one working properly. The drainage blockage is caused by the fact that the flare system was not properly purged before its initial operation, or there was too much dirt present; cleaning the separation tank again, as well as thickening or modifying the drainage pipes, will solve the problem.
A separate tank is required as a mandatory element to prevent water accumulation and avoid liquid shock in the pipes
The one on the torch is a liquid seal; if dust is present in the air being released, it’s easy for this seal to get clogged. By adding a larger separation tank upstream of it, it’s also possible to wash away the dust with water.

It must be added. Generally, a separation tank needs to be installed every 200 meters or so along the flare pipeline in case of accidents; many companies have encountered problems already, so care must be taken. A few jars don’t cost much money.
Our unit is equipped with a flare water seal tank, which serves to prevent backfire
Small separation tanks should be installed every 200 meters or so, and a larger horizontal separation tank should be placed before the material enters the flare stack; make sure proper heat tracing and insulation are in place! ! ! The separation tank beneath the torch is liquid-sealed; this water-sealing tank has a drain pipe at its bottom, as well as a U-shaped overflow pipe to maintain its liquid level. But blockages often occur. Therefore, a separation tank must be added in front of the torch. Otherwise, if the water seal level is too high, the flare will carry water! !
A vent separator tank should be installed; otherwise, contamination is likely to occur during venting.
Our refinery’s flare system is equipped with a water seal tank and a liquid separation tank. The water seal tank is used to prevent liquids from entering the flare system during venting, thereby avoiding the risk of firestorms; its installation is necessary
