Suction heaters vs heat tracing

Suction heaters vs heat tracing

Suction heaters vs heat tracing

Dear all,

I'd like to get your kind advice about the installation of suction heaters vs heat tracing in the following case:

It is a 24000 m3 LDO tank, whose pour point is -9ºC and it must get to the transfer pumps at a minimum temperature of 10ºC. The minimum ambient design temperature is -7ºC.

I am wondering how to choose the most correct configuration among the following ones:

* Heat tracing in the tank to keep tanks contents at a temperature higher than the pour point plus a margin (for example -4ºC) and heat it up from -4ºC to 10ºC with a suction heater.

* To use the heat tracing to keep the tanks contents at 10ºC.

* Not to install heat tracing and use a suction heater to heat the fluid up to 10ºC only with the suction heater.

Thank you for the help
