We currently have a 50m3 silicon tetrachloride storage tank, and the discharge pump has a maximum output of 200 KG/h. Please help calculate the nitrogen flow rate required for nitrogen sealing; any expert who can provide some advice would be appreciated

According to HG/T 20570.16-95 \"Installation of Air Seals\", the air supply volume for the air seal device in storage tanks should be greater than or equal to the sum of the air required to replenish the liquid removed from the tank by the pump, and the air needed to compensate for the condensation and contraction of gas within the tank due to changes in external temperatures. (1) The amount of air required to be pumped out to remove the liquid stored in the tank is equal to the pump’s maximum output capacity. 200/1480=0.135 Nm3/h (2) The amount of gas that needs to be added due to the condensation and contraction of the gas inside the storage tank as a result of temperature changes. The gas supply requirement for a 50m3 storage tank due to changes in external temperature is 9 Nm3/h, while the gas supply required for nitrogen sealing is 9.135 Nm3/h
