CO2 corrosion inside gas pipelines
CO2 corrosion inside gas pipelines
(OP)
I am looking at a wet gas pipeline with a small quantitiy of C02 in the gas composition (1 to 2 % mol). The pipeline pressure is in the rage of 5 to 10 bars.
I think I remember, from a long time ago, about a rule of thumb which states that, below a certain value of partial pressure of CO2, the reactions between the CO2 and the water can be regarded as insufficient to initiate any significant internal corrosion.
Am I talking rubbish ?
If not, can anybody throw some more light on this rule of thumb (what is the threshold value of the partial pressure)?

You could try to check out this NORSOK page where they even provide you with a spreadsheet for calculating corrosion:
