For the venting section of storage tanks, is it better to use a nitrogen seal or a water seal?
It mainly depends on whether the volatile components are soluble in water; if not, nitrogen sealing is used, while if they are soluble in water, water sealing is employed
It is determined based on the properties of the substance in the tank.
Check the process requirements. If both are possible, it is recommended to use a water seal, as it is intuitive and easy to operate.
I have seen more nitrogen seals, and the control of those nitrogen seal valves is also very stable
Each has its own advantages. Generally, modular processes are safer, with nitrogen being introduced through inhalation and exhaust gas passing through a water seal.
Based on the material properties, it will form a water seal when dissolved in water
Depending on the properties of the material, if it is a flammable organic solvent, a nitrogen seal valve + single exhaust valve is generally used. The one-way valve of the VOC should lead to the exhaust gas collection device.
