I'm looking at options for an oil and gas production pipeline (feasibility stage), the produced fluids have a high CO2 content (circa 18-20 mol%) and the reservoir conditions are close to dew point, no H2S. Its safe to say carbon steel will not work as a pipeline material, is there a guide or rule of thumb for what grade CRA material (or a lined/clad pipeline) would be required? Temperatures are also high at up to 110degC. I don't think 13cr would work either at that CO2 / water levels. So assume would be looking at 316L, 904L, super duplex etc?
