A balance pipe is used for feeding into the storage tank
Thread Content
Does the storage tank have a nitrogen seal, and can feeding be used as a balance pipe? Can the tail gas from tank L be left untreated after using a balance pipe?
It is recommended to draw a diagram of the relevant processes for this tank, indicating the pressure media in each section. This way, the principle of the device and how to use it properly can be understood at a glance; give it a try.
1. A balance pipe can be used for feeding, but this is possible only if the nitrogen sealing pressure is within the range that the discharge tank truck (ship) can tolerate; moreover, proper sealing must be ensured to meet environmental requirements； 2. Additionally, taking into account the thermal expansion and contraction of the material inside the storage tank as well as the performance of the corresponding gas-phase seals (such as vent valves), exhaust gas treatment is still necessary
