چکیده انگلیسی
In the Carbon Capture, Transportation & Storage (CCS) process, CO2 is captured with impurities such as N2, CH4 and Ar and is transported under a supercritical state. In this study, the characteristics of in-tube convective heat transfer of CO2 mixtures such as CO2â¯+â¯N2, CO2â¯+â¯CH4 and CO2â¯+â¯Ar were experimentally investigated under the land transportation conditions of the CCS process. The test tube was made of a cooper tube buried in a PVC (Polyvinyl Chloride) pipe which was compactly filled with sand, which simulated the land CO2 transportation. Mass flux was changed by 200, 400 and 600â¯kgâ¯mâ2â¯sâ1, and operational pressures were 80, 90, and 100â¯bar. Operational temperatures ranged from 25 to 55â¯Â°C. The heat transfer coefficient of the CO2 mixtures dominantly followed the trends of pure CO2; however, they were decided by the type and quantity of the impurity. When the CO2 mole fraction was changed from 1.00 to 0.95, the maximum heat transfer coefficient at the pseudo-critical temperature of CO2â¯+â¯N2 and CO2â¯+â¯CH4 decreased by 4389â¯W·mâ2â¯Kâ1 and 2770â¯W·mâ2â¯Kâ1, respectively. As the mass flux increased, the heat transfer coefficient increased in all of the CO2 mixtures.
