Regarding the calculation of the relief valve discharge volume: maximum heat transfer under operating conditions

This post was last edited by vicshl on 2018-10-16 at 15:11. How is the heat transfer rate on the process pipeline calculated? Should it be based on the heat load of the upstream heat exchanger? There is another question: When the safety valve is connected to the equipment or pipelines, should the diameter used for calculating the discharge volume be based on the inner diameter of the pipeline directly connected to the safety valve, or should it be based on the inner diameter of the pipeline used in normal operation?
I don’t know the first one; the second one should be the inner diameter of the pipe
First, check whether it relates to the heat of vaporization and then perform the calculation; the second is likely the diameter of the process pipe at the inlet
