“…On the contrary, the usage of Eulerian multi‐fluid methods could be a promising approach for simulation of gas–liquid flow and mass transfer in pilot‐scale or large‐scale chemical reactors due to the lower requirement of computational grid and shorter calculation time 24 . Currently, Eulerian multi‐fluid approach has been widely used in studying the liquid dispersion, 25 hydrodynamic behaviors, 26–31 and CO 2 absorption 32–34 in conventional packed beds or trickle beds. Eulerian two‐fluid model with a porous media model 35–37 and Eulerian three‐fluid model 38 are commonly used in these CFD studies.…”

Rotating packed beds (RPBs) are ideal candidates for CO2 removal from offshore natural gas due to their good mass transfer performance and significant volume savings. This article proposes an Eulerian multi‐fluid approach to simulate the gas–liquid flow in RPBs. Three new multiphase drag force models are constructed based on single‐phase drag force models for wire mesh packings. Based on the Eulerian multi‐fluid approach, a new RPB simulation framework is developed. The predicted results using the new simulation framework with the new drag force models are compared with the experimental data. When using the Kołodziej model and the modified Kołodziej model, the predicted overall liquid holdup shows good agreement with the experimental data with errors less than 20%. In addition, the pressure drop predicted by these three models are reasonable compared with the experimental data. This work lays a foundation for RPB simulation of gas–liquid flow using Eulerian multi‐fluid approach.

“…Pan et al [15] developed a validated device-scale CFD model that could predict quantitatively both hydrodynamic and CO 2 capture efficiency for an amine-based solvent absorber column with a random Pall ring packing. Gbadago et al [64] used CFD to investigate a multi-packed bed amine absorption column with interbed liquid distributors on an AMT SP-350Y structured packing by dividing the packed column into five beds. They used a Eulerian multiphase model for the study.…”

CO 2 emission is an important environmental issue leading to global climate change, notably an increase in global temperatures; therefore, it is so imperative to reduce CO 2 emissions to the atmosphere. Absorption columns using amine-based solutions are a promising approach for CO 2 removal from industrial gas streams. Many modeling and simulation research have been performed on CO 2 absorption columns in which computational fluid dynamics (CFD) strategy is very appropriate and well-known. As CFD modeling and simulation is a fast-developing method, the most recent review papers do not include the core research in this field of study. In this study, numerical simulations of CO 2 absorption columns using CFD strategy have been carried out applying various types of aminebased solutions. Furthermore, the effect of various types of packing mesh generation on the absorption columns' efficiency was studied. Investigation of synergetic influence such as application of various nanoparticles in different amine-based solutionsand activators, double diameter packed bed absorption columns with different packings, rotating packed columns with double diameter are proposed for future studies.

“…A gas-phase catalytic reaction simulation through a particle-filled fixed bed reactor was executed. The detailed description of numerical discretization techniques and boundary conditions in this work adopted from our previous study [35] are given in Tables 4 and 5. The packed bed was assumed as a continuous porous media to include the effect of pressure drop and heat transfer.…”

The oxidative dehydrogenation (ODH) of butene has been recently developed as a viable alternative for the synthesis of 1,3-butadiene due to its advantages over other conventional methods. Various catalytic reactors for this process have been previously studied, albeit with a focus on lab-scale design. In this study, a multi-tubular reactor model for the butadiene synthesis via ODH of butene was developed using computational fluid dynamics (CFD). For this, the 3D multi-tubular model, which combines complex reaction kinetics with a shell-side coolant fluid over a series of individual reactor tubes, was generated using OpenFOAM®. Then, the developed model was validated and analyzed with the experimental results, which gave a maximum error of 7.5%. Finally, parametric studies were conducted to evaluate the effect of thermodynamic conditions (isothermal, non-isothermal and adiabatic), feed temperature, and gas velocity on reactor performance. The results showed the formation of a hotspot at the reactor exit, which necessitates an efficient temperature control at that section of the reactor. It was also found that as the temperature increased, the conversion and yield increased whilst the selectivity decreased. The converse was found for increasing velocities.
