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

Performance Prediction of Eddy Current Flowmeter for Sodium

P. Sharma[1], S. K. Dash[1], B. K. Nashine[1], S. S. Kumar[1], R. Veerasamy[1], B. Krishnakumar[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1] Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to ... Read More

Kinetic Parameters for Gas Phase Photocatalysis: Analytic Versus CFD Approach

S. Denys[1], S. Verbruggen[1], S. Lenaerts[1]
[1]Sustainable Energy and Air Purification, Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

Introduction Among the advanced oxidation processes (AOPs) for removal of volatile organic compounds (VOCs) from air, photocatalytic oxidation (PCO) is considered a very promising technology [1,2]. PCO can achieve mineralization of harmful VOCs to CO2 and H2O using only UV light [3]. A ... Read More

Sensitivity Analysis of CPP’s for Solvent Removal Process of a API-Protein Bonded Nano-Suspension

C. C. Huang [1], T. Liu [1], F. Faassen [1],
[1] Teva Pharmachemie B.V., Haarlem, The Netherlands

Solvent extraction and evaporation is a widely used unit operation in the manufacturing of micro and nano-particles. Due to the weak bond of the API to the protein, the product is highly sensitive to temperature, mechanical mixing and extraction/evaporation rate. A slow extraction ... Read More

Thermal analysis of a spent fuel transportation cask

P. Goyal[1], V. Verma[1], R. K. Singh[1], and A. K. Ghosh[1]
[1]Reactor Safety Division, Bhabha Atomic Research Centre, Trombay, Mumbai, India

Spent fuel transportation casks are required to meet among others (test conditions), the regulatory thermal test conditions in order to demonstrate their ability to withstand specified accidental fire conditions during transport. This paper describes the transient thermal analysis ... Read More

Understanding Transport Phenomena Concepts in Chemical Engineering with COMSOL Multiphysics®

E. S. Vasquez [1],
[1] Department of Chemical and Materials Engineering, University of Dayton, Dayton, OH, USA

Transport Phenomena in Chemical Engineering involves three key aspects: Momentum, Heat and Mass Transport. These areas are described by differential equations which are solved for a particular problem using independent or a set of combined equations (e.g., water flowing in a heated ... Read More

Finite Element Modeling for Inspection of CANDU® Steam Generators

S. G. Mokros[1], P. R. Underhill[2], J. Morelli[1], T. W. Krause[2]
[1]Department of Physics, Engineering Physics & Astronomy, Queen's University, Kingston, ON, Canada
[2]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

Steam generators (SGs) are used in CANDU® nuclear reactors as heat exchangers to convert water into steam using heat generated in the reactor core. Ferrous trefoil broach support structures prevent excessive vibration of thousands of SG tubes. A probe that uses pulsed eddy current (PEC) ... Read More

Modeling of Packed Bed Reactors: Hydrogen Production by the Steam Reforming of Methane and Glycerol

A. Dixon[1], B. MacDonald[1], A. Olm[1]
[1]Department of Chemical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

The conventional route to hydrogen production is by steam reforming of methane (MSR) in a multitubular packed bed. With the increasing use of biodiesel as a renewable fuel, interest has grown in steam reforming of the excess glycerol produced as a side product (GSR). We use COMSOL ... Read More

CFD Modeling of a Laboratory-Scale Setup for Thermochemical Materials Performance Analysis

S. Salviati [1], N. Vasile [1], F. Carosio [2], G. Saracco [2], A. Fina [2],
[1] Center for Sustainable Future Technologies, Istituto Italiano di Tecnologia, Torino, Italy
[2] Dipartimento di Scienza Applicata e Tecnologia, Politecnico di Torino, Alessandria, Italy

The search for energy saving is nowadays mandatory because of the constant growth of CO2 emissions caused by an inefficient energy management. Thermal Energy Storage (TES) has an important role in designing of energy efficient systems, including solar energy storage (daily or seasonal) ... Read More
