Calculation of nitrogen consumption for nitrogen sealing in atmospheric pressure storage tanks
Thread Content
The nitrogen pressure produced by the nitrogen generator is 6 bar, while the operating pressure of the nitrogen in the storage tank is 1500 Pa； The operating pressure of the nitrogen storage tank is 6 bar, and its volume is 2 m3. Then, how many cubic meters of nitrogen can the compressed nitrogen in the tank expand to at a pressure of 1500 Pa? I wonder how to calculate this – should standard atmospheric pressure be taken into account? Please provide a reasonable and simple calculation formula, thank you!
6 bar = 0.6 Mpa; absolute pressure to be used for calculation is 0.7 Mpa. 1500 Pa is approximately equivalent to 0.1 Mpa; multiplying by 7 gives 14 cubic units
