| Abstract | Despite the efforts that have been made to develop novel technologies generating clean and renewable energy during the past years, fossil fuel combustion will still be the major source of energy supply
in the near future. The combustion of fossil fuel will generate lots of CO2, which is the primary source of climate change and global warming. To deal with this situation and ensure the sustainable development of human being, carbon capture and
storage (CCS) has been proposed and developed rapidly to control the CO2 emission while retaining the core values of fossil fuel power plants. During the CCS technology, long-distance transportation of CO2 from power plants to storage sites is
usually achieved by the pipeline network, which could deliver large amounts of CO2 at a relatively low expense. During the transportation, the captured CO2 streams are usually compressed into the supercritical state (supercritical CO2, short as
s-CO2) to increase the efficiency. |
| Summary | (Plain Language Summary, not published)
To control greenhouse gas emission, huge amounts of CO2 generated at thermal power plants needs to be captured and transported to specific sites for
permanent storage or further utilization. During long distance pipeline transportation, small amounts of impurities (like SO2, O2, H2O, etc.) always present in the transported supercritical CO2 streams and likely cause severe corrosion damage to the
pipeline integrity. The results in this study show that the moderate addition of alloying element Cr (2 wt.%) into conventional pipeline steels can lead to the formation of protective corrosion layer on the steels to effectively resist the
environmental attack. It provides a valuable information on the selection and further development of supercritical CO2 pipeline steels. |
