Carbon Dioxide corrosion
Carbon Dioxide corrosion
(OP)
I'm looking for a coating system for an internal epoxy lining of some carbon steel vessels.
The stream is wet natural gas with the presenze of carbon dioxide with a partial pressure under 11 psia.
Thanks

maybe you can find more info on NACE website or the NACE coating network forum.

Specifically take a look at: http://www.composite-agency.com/messages/4758.html (this thread is about long term service life of grp under the load of corrosive chemicals).

In every case, using dewaard-milliams model, i calculated the approximate corrosion rate and i don't think i'll have many problems. Also because i think that this model is very conservative.

In every case my paint supplier gave me a lining system for the co2, in wet stream corrosion attack.

Taking in consideration the last case, my owner ask me to change material. Upgrading the material in my case means using SS instead CS. For avoiding this upgrade, i was looking for a epoxy coating system for a carbon dioxide corrosion in a wet system.
The use of dewaard-milliams system is only to understand if, using 3mm of corrosion allowance with CS, 20 years of lifetime of the plant could be granted. But of course, it was only an "academic" attempt, because firts of all it's everywhere underlined that this model is very conservative and then i was taking in consideration the worst case (dehydration unit in shut-down and the plant still in operation).
