Requirements for installation and use of reaction vessel venting tubes
Dec 08, 2018

The venting tube of the reaction vessel should generally be placed at the top, and the venting tube installed in the indoor container should be led out of the room. The venting pipe should have a height higher than 2m above the highest equipment operated by some people nearby, and ensure that the concentration of flammable gas discharged is within the safe range.


After the reaction vessel is discharged, the combustible gas that may be immediately burned should be cooled by the cooling device and then connected to the venting facility. Flame arresters or other flame-limiting equipment should be installed on the venting tube to prevent the gas from igniting at the outlet of the pipe and allowing the flame to diffuse into the process unit. The venting pipe should have good grounding and the nozzle should be within the lightning protection range. The accident storage tank should be installed in a safe area, the reaction vessel in the factory, and the liquid in it should be discharged to the underground or semi-underground special accident storage tank or discharge tank located outside the factory.


The reaction vessel needs to be equipped with an automatic accident interlocking system to some extent, such as an interlock device for the temperature of the material and the amount of catalyst added: a pressure or temperature limit adjustment alarm device. When the parameter is out of the safe range, automatic adjustment can be made immediately. If the adjustment is invalid, an alarm signal can be issued to notify the operator to take emergency measures to eliminate the fault. If the fault is improper or not timely, the automatic control system can issue commands such as switching, venting, and extinguishing
