Dear Sir,
Please advise on how to calculate the size for a breather valve, which is a tank safety and protection device. I need to determine the appropriate breather valve size for three units of tanks. The tank size is as follows: diameter 2600x6650mm height (internal diameter).
These tanks are connected to three units of transfer pumps, with a flow rate of 50m³/hr each, resulting in a total flow rate of 150m³/hr. The return flow is assumed to be 30%, which means it is 50m³/hr.
Additionally, the blanketing N2 pressure is 30mbar.
Could you please guide me on how to calculate the breather valve size? Should it be a 4-inch or 2-inch valve?
Thank you for your assistance.
Sincerely,
