"Naphtenic acid corrosion"
Question:
"We are
begining to run a crude called KUITO with a 2.2 TAN theroretical.
and 2.7 real. Our slate will be impacted whit no more than 20%
of it. We installed a set of corrosion probes and are ready to
inyect inhibitors as needed. My question is : does anyone have
experience in running this type of crudes up to now ?. If so, plese
send me a short comment about unexpected corrosion and place to
find it (I would mean, the stream to monitor for metal loss) "
Answer:
Nalco/Exxon Energy Chemicals, Betz-Dearborn and Baker Petrolite are providers of corrosion inhibitors for naphthenic acid corrosion. They have a database of most of the crude oils around the world with their corrosion properties in the distillation units. Contact them and try to get an assessment of the Kuito crude.
