Abstract

Recently, with the acceleration of global warming, the importance of carbon neutrality is being emphonasized. In response to this, various technologies are being developed to achieve carbon neutrality, with Carbon Capture, Utilization, and Storage (CCUS) being a prominent example. Research has been conducted on the injection technology to environmentally discharge carbon captured by using one of the carbon capture technologies, HAK-CRS. In this study, numerical simulations were performed using commercial software, ANSYS Fluent, to understand the dispersed multiphase flow between a water jet and CaCO3 particles. The analysis focused on the differences in particle behavior when injecting CaCO3 with different flow rates. It was observed that as the mass flow rate of CaCO3 increased, there was a tendency for the particles to deviate from the flow of the jet and rapidly fall, influenced significantly by gravity. These results indicate that, for CaCO3 particles to disperse widely, the flow rate should not be excessively high. Given the potential adverse impacts on marine ecosystems due to the high density of CaCO3, research on injection technology should also be conducted.
