Temperature drop is a function of…
+ velocity, distance, diameter, etc
+ reactivity (parafinic vs naphthenic vs asphaltenes/ccr etc)
+ Coil outlet temp, COT
+ Measurement location (not all COT and drum inlet Ti’s are in the same place)

That being said…. typically we expect 15-25degF drop in the transfer line.

What are you seeing?
