Heat transfer performance of single atom solution in carbon dioxide capture circulation system

In order to accurately assess the heat transfer performance of the new single atom solution for carbon dioxide capture, an experimental system and heat transfer model have been developed. This study focuses on the effects of flow rate and temperature on the heat transfer performance. It is found that the effect of temperature on their heat transfer characteristics is not significant, and increasing flow rate enhances heat transfer. The heat transfer coefficient is increased by 45% as the diameter of the heat exchange tube is reduced. The theoretical heat transfer performance of single atom solutions is 18∼37% higher than that of common solvents. Additionally, the numerical simulation results showed that single atom solutions greatly reduced desorption energy consumption to 1.447 GJ/t. The results provide new technological support for carbon capture.
