reactions of CO2, H2, H2S, and water...under pressure

reactions of CO2, H2, H2S, and water...under pressure

(OP)
could anyone tell me of mixed reactions between CO2, H2, H2S and water that could create a corrosive environment in contact with mild steel?

CO2 readily dissolves in H2O to make carbonic acid, at room temperature.

does H2S dissolve to form sulfuric acid?  at temperatures of around 60C and concentrations of only 50PPM? 300PSI?

is there anything i should be watching for here?

RE: reactions of CO2, H2, H2S, and water...under pressure

No, hydrogen sulphide (H2S) does not dissolve in water to make sulphuric acid - sulphur dioxide (SO2)does.
