Dear Paul,
Yes, definitely, steam tracing would be the most
efficient and economical solution to almost all the
process-fuid heating schemes. That is fine as far as
the steam is available at the facilities. There are
locations like isolated offshore platforms, and to
keep the stagnant oil lines and drain systems in
flow-able condition, the only choice, probably is the
electric tracing. That gains more significance when
the flowlines contain high waxy components.
Regards.
