Fracture Propagation and Fracture Control for superctitical CO2 piping
Fracture Propagation and Fracture Control for superctitical CO2 piping
(OP)
I want to choose the material for a supercritical CO2 piping.
The CO2 stream composition is:
- Carbon dioxide (CO2) Vol% > 99.6
- Water (H2O) ppmv < 500
Parameters are:
T > 40 degrees C;
P > 120 bar;
If the corrosion rate of supercritical CO2 piping is lower (until now I have no confirmation), then I will have to take into consideration all scenarios (for example depressurizing CO2 from high pressure)...
As you know, Fracture Propagation and Fracture Control are big issues, in order to choose the BEST CARBON STEEL piping material... Can you recommend me a document or a software, in order find more info, regarding to Fracture Propagation and Fracture Control for supercritical CO2 piping.
Thank you very much for your advice.

Do you know a software or a link to a interesting document, in order to estimate the Fracture Propagation (in case of depressurizing CO2 from high pressure). Any info could help me. Thanks.

Of particular note is the apparent paradox to hydrocarbon pipelines in that lower pressures and higher temperatures can be more severe. What the paper will also show you is that surfing a forum such as this for design assistance may not be the most effective approach.
