“…In recent years, Roland, Sommerfeld, Lain, and Taborda − have used the Euler–Euler and Euler–Lagrangian models for numerical simulation. The results show that these two models are suitable for the dynamics of bubbles in gas–liquid mixed multiphase flow, especially for the bubble characteristics of CO 2 bubbles in bubble columns.…”

Carbon dioxide (CO 2 ) bubbles are common during carbon capture, utilization, and storage (CCUS) processes and have many impacts on water conservancy machinery, metallurgy, and the chemical industry. To explore the dynamic characteristics of CO 2 bubbles in different liquids in CCUS, the motion mechanism of CO 2 bubbles was integrated, and the effects of different liquid characteristics and different external conditions on the dynamic characteristics of CO 2 bubbles were classified and summarized. At the same time, the research progress of numerical simulation on CO 2 bubble dynamics is reviewed. Therefore, approaches and methods that can be further explored in theoretical analysis, experimental research, and numerical simulation of CO 2 bubble dynamics are proposed, which can provide reference and guidance for engineering practice, especially CCUS technologies.

“…The Euler-Euler approach was employed in a two-dimensional domain employing a uniform rectangular mesh to simulate twophase gas-liquid laminar flow. Taborda et al (2021) studied the bubble dynamics and the absorption of CO2 in NaOH solution in a bubble column simulated by CFD using the Euler-Lagrange approach. The bubble size distribution parameters were changed in function of mass transfer, coalescence and bubble breakage.…”

Gas scrubbers are important equipment for air pollution removal. Among the scrubbers we can highlight the spray tower, which has several advantages, such as low pressure drop, easy maintenance and low operational costs. However, the velocity profile inside this equipment is complex, making its analysis and design very difficult. Therefore, the present work aims to perform numerical simulations using CFD (Computational Fluid Dynamics) using Euler-Lagrange approach applied to a spray tower for SO2 absorption. The simulations evaluated the influence of the following variables on velocity and SO2 profiles, as gas and liquid flow rates, size droplet distribution and spray nozzles with different orifice diameters. The results obtained by CFD simulations showed the main absorption zones in the column and the influence of gas velocity, particle trajectories and droplet diameter in the sulfur dioxide absorption process. Furthermore, the experimental efficiencies were compared with the simulated for two conditions, the first condition with an experimental efficiency of 89% presented a simulated efficiency of 79.6% and the second condition with an experimental efficiency of 98.27% presented a simulated efficiency of 100%. This shows a good approximation between the simulated and experimental results
