Seeking advice on the discharge capacity of the heat exchanger (safety valve)
Thread Content
I’m seeking advice from fellow users: when calculating the size of safety valves for heat exchange vessels, do any of you have good methods for determining the discharge volume?
The calculation of the discharge volume from a heat exchange vessel requires considering the vessel’s operating pressure, temperature, and the properties of the fluid. A common approach is to use API or ASME standards, calculate the discharge capacity of the safety valve using formulas, and then select an appropriate size for the safety valve based on that calculation. For specific details, refer to the relevant provisions of API 520 or ASME Section VIII. .
Are you referring to the scenario where the heat exchange tube ruptures? Similar to orifice plate calculations, if you search for the formulas, there are many options available
Refer to HG/T 20570.2-1995; calculations are performed under specific operating conditions
The heat exchange tube failure condition applies only when the medium is in liquid phase
