For atmospheric pressure material tanks equipped with nitrogen blanketing and flame arrestor vent valves, what is an appropriate setting for the opening pressure of these vent valves?
The pressure of the flame arrestor breather valve is probably around 1500 Pa higher than that of the nitrogen seal valve; it depends on the design
It is determined by estimating the design pressure of the storage tank! Taking a storage tank with a design pressure of 2 KPA as an example, the nitrogen seal is set at 200–500 Pa, the single vent valve is set at 900 Pa, and the breather valve is set at 1300 Pa!
