State of the aqueous phase in liquid and supercritical CO2 as relevant to CCS pipelines
In the transportation of CO2 via steel pipelines in the CCS (Carbon Capture and Storage) process, a range of impurities may exist in the CO2 stream. Of the most important to the durability of pipelines with respect to corrosion damage, is the presence of an aqueous (water) phase. The reason for this...
