Dear Sir,
I think that the most probable reason for corrosion is flashing of H2S. That is typical in absorber bottom and rich line exchanger.
In any case the operating temperature seems to me too high. Normally amine temperature should not excedd 38 °C, in order to optimize abosrption. Gas...
Dear Taylorg,
the question you should first ask is "What is the cost of not processing an acidic crude and processing a normal crude oil to avoid corrosion problems?".
The price difference between an acidic and a normal crude oil is so big that any treatment cost is fully justified.
In aany case...
Kresimir,
as observed by pkpbip and 25362 water washing is the proper practice to prevent deposition of inorganic salts in HDS effluent coolers.
To prevent the corrosion that could occur in presence of water a corrosion inhibiton program should also be applied.
Best regards,

Daer MaNaTMos,
as explained by other people TAn is a standard ASTM test.
NAN is a proprietary method e therefore you will not find too much about it.
It has been developped to better identify which areas of a crude atmospheric or vacuum disttilation can be subject to corrosion by naphtenic...
