ECE Corrosion Prediction Model

ECE Corrosion Prediction Model

ECE Corrosion Prediction Model

(OP)
Hi Everyone,

Does anybody know how ECE model deals with H2S? i.e. if H2S is present does it multiply the CO2 corrosion rate with a certain factor and gives the overall corrosion rate?

I want to understand how it deals with slightly sour and very sour systems (pCO2/pH2S > 500 and pCO2<pH2S < 20).

Thanks,
Corroneer

RE: ECE Corrosion Prediction Model

According to NACE Publication 21413, H2S has a "strong effect" on CO2 corrosion rate predictions made with ECE. From very recent experience, that effect is in the reduction direction. Nevertheless, the best place to have your question answered is the user manual for the software.

RE: ECE Corrosion Prediction Model

The ECE software is derived from published research papers on H2S corrosion of carbon steel and some stainless steel materials.
For each one they have an experiment curve that is interpolated. A warning is indicated if there is extrapolation.

* Finding a solution is great * Knowing how to implement it is fantastic * Believing it is the only one and best is naive ?
