Hi All,

 

I need to size a hot oil heat tracing line to maintain bitumen at a constant temperature of 140C for a steady state scenario when the bitumen is not flowing and flowing. The hot oil tracing will come off a main header, and will be installed on the piping in 50m sections, discharging to a return header. The available inlet hot oil temperature is 260C, mass flow rate to be determined (subject to effectiveness of heat transfer to pipe).

 

Can anyone offer a methodology and calculations to establish the effective heat transfer rate between the hot oil trace line and large bore pipe to overcome the heat lost from the system?

 

I am aware that the use of heat tracing cement will improve the conduction efficiency between the heat trace line and the pipe, however, cannot quantify how much heat is transferred

 

I am also seeking to confirm that more heat will be lost from the bitumen when it is not flowing.

 

Thank you and looking forward to receiving your collective advice.
