CORROSION RATE IN GAS WITH CO2

[ferchuvicente]

HI, I WOULD LIKE TO KNOW HOW I CAN TO CALCULATE THE CO2 CORROSION RATE AT LOW TEMPERATURES (-6ºC FOR CARBON STEEL,AND -95 FOR STAINLESS STEEL304).
tHE PRODUCT IS NGL FROM THE BOTTOM OF DEMETHANIZER TOWER.

CAN I APPLY THE CLASIC MATHEMATICAL MODEL TO CALCULATE THE CORROSION RATE?

Which "classic mathematical model" would you attempt to use: de Waard-Milliams? Unfortunately, it won't work with stainless steel let alone at -95 deg C (is there an aqueous phase at that temperature?). NORSOK M-506 only works down to +5 deg C.

thank you, what about carbon steel? yes i have used the mathematical model of williams. But it will work with carbon steel at low temperatures and co2 in hydrocarbur liquids, such as propane, butane.
