Simulation of Gravitational Instability During CO₂ Absorption in a NaHCO₃/Na₂CO₃ Solution

C. Wylock[1], A. Rednikov[1], B. Haut[1], P. Colinet[1]
[1]Université Libre de Bruxelles (ULB), Transfers, Interfaces and Processes (TIPs), Brussels, Belgium

This work deals with the modeling and the numerical simulation of the CO2 absorption, coupled with a chemical reaction, in an initially quiescent aqueous solution of sodium carbonate (Na2CO3) and bicarbonate (NaHCO3), inside a Hele-Shaw cell. In our Hele-Shaw cell, the liquid fills ... Read More

Modeling an Adsorption Process in a Shell-and-Tube-Heat-Exchanger-Type Adsorber

G. Salazar Duarte[1], B. Schürer[1], C. Voss[1], D. Bathen[2]
[1]Linde AG, Munich, Germany
[2]Universität Duisburg-Essen, Duisburg, Germany

Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) are commonly used for separation/purification of gas mixtures in industrial processes. The cycle time of industrial TSA processes usually ranges from several hours to days. The reason for this long cycle time is the ... Read More

A COMSOL-based 2D Self-Consistent Microwave Plasma Model

A. Berthelot [1], A. Bogaerts [1],
[1] PLASMANT Group, University of Antwerp, Belgium

In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the ... Read More

Simulation and Analysis of a Borehole Transient Electromagnetic Reservoir Monitoring System

S.M. Dutta[1], A. Reiderman[1]
[1]Baker Hughes, Houston, TX, USA

Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper ... Read More

Supercritical CO2 Leakage Modelling for Well Integrity in Geological ...

Supercritical CO₂ Leakage Modelling for Well Integrity in Geological Storage Project

E. Houdu, O. Poupard, and V. Meyer
OXAND S.A., France

CO2 capture and storage constitutes a promising solution to control and reduce these emissions. Wellbore integrity is a key challenge to ensure long term safety and for public acceptance. For this objective, a two-phase flow model in porous media based on Darcy’s law has been proposed to ... Read More

Study of the CO2 Transfer Rate in a Reacting Flow for the Refined Sodium ...

Study of the CO₂ Transfer Rate in a Reacting Flow for the Refined Sodium Bicarbonate Production Process

C. Wylock[1], A. Larcy[1], P. Colinet[1], T. Cartage[2], and B. Haut[1]
[1]Université Libre de Bruxelles, Brussels, Belgium
[2]Solvay S.A., Brussels, Belgium

This work deals with the quantification of the CO2 transfer rate from a bubble to the surrounding liquid in a bubble column. A model is successfully developed using COMSOL Multiphysics. The validated model is used to study the enhancement influence of chemical reactions on the transfer ... Read More

Pseudo 3-D Simulation of a Falling Film Microreactor

M. Al-Rawashdeh[1,2], V. Hessel[1,2], P. Löb[1], and F. Schönfeld[1]
[1]Institut für Mikrotechnik Mainz GmbH, Mainz, Germany
[2]Department of Chemical Engineering and
Chemistry, Eindhoven University of Technology, Eindhoven, Netherlands

Gas-liquid falling film microreactors carry out fast exothermic and mass transfer limited reactions. Since the major rate limiting steps occur on the liquid side, it is important to account for a realistic liquid film profile within the reactor simulation. Based on realistic channel ... Read More

Zinc Corrosion in a Crevice

C. Taxén, and D. Persson
Swerea-Kimab, Stockholm, Sweden

Corrosion of metals in confined zones is a big industrial problem. The electrochemistry of such localized corrosion processes is complicated by the impact of the corrosion processes on the composition of the local solution. In the present problem, local interaction with the atmosphere ... Read More

Reliability Evaluation for Static Chamber Method at Landfill Sites

H. Ishimori[1], K. Endo[1], and M. Yamada[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

In this study, COMSOL Multiphysics was used for the reliability evaluation for static chamber method at landfill sites. Static chamber method, which measures landfill gas emission fluxes, is widely used at landfill sites for the monitoring of greenhouse gas emission such as methane and ... Read More

Simulation of a Diesel Oxidation Catalyst Used in a NO_x Storage and Reduction system for Heavy Duty Trucks

C. Odenbrand, and E. Senar Serra
Department of Chemical Engineering, Lund University, Lund, Sweden

This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic ... Read More
