CFD Investigation of a Photocatalytic Multi-Tube Reactor for Indoor Air Purification

J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1], S. Denys [1],
[1] Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

In industrial countries, people spend most of their time indoors. Stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality [1]. Integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow ... Read More

A Multi-physical Approach of a Sterilization System for Aseptic Food Processing

Sterilization is the process of deactivating microorganisms from a surface or a product. A high temperature gaseous mixture of hydrogen peroxide and steam became the accepted standard in most aseptic filling machines found in pharmaceutical, food and beverage industries [1, 2]. To ... Read More

Hydrothemal Carbonization: A Renewable Alternative to Fossil Fuels and Respective Evaluation

P. Kladisios [1], A. Stegou [1], Z. Sagia [1],
[1] National Technical University of Athens, Athens, Greece.

Humanity is faced with an imminent energy crisis. The exponential growth of the human population and the consequential increase of the required energy on a global scale, the dramatic climate change and the exhaustibility of natural resources combined, force us to strive towards a ... Read More

Modeling and Simulation of Hydrogen Generation in Membrane Reactor via Steam Octane Reforming

N. Ghasem [1], A. Y. Alraeesi [1],
[1] UAE Univeristy, Alain, United Arab Emirates

Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane ... Read More

A Flow and Transport Model for Low-Temperature Gaseous Nitrocarburizing of Stainless Steels

J. Feng [1], M. Wettlaufer [1],
[1] Centre of Materials Engineering, Heilbronn University, Heilbronn, Germany

An integrated numeric, thermodynamic, and experimental analysis work was conducted to find out the proper flow and transport parameters of combined chemical species for low-temperature gaseous nitrocarburizing of stainless steels in an industrial furnace built for thermochemical ... Read More

Reactive Transport Modeling of CO2 in Carbonate Rocks: Single Pore Model

P. Agrawal [1], J. Koskamp [1], A. Raoof [1], M. Wolthers [1],
[1] Utrecht University, Utrecht, The Netherlands

Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the ... Read More

Model Based Stimulus Experiments to Improve Biological Wastewater Treatment Performance

N. Do [1], M. Stich [1],
[1] Non-linearity and Complexity Research Group, System Analytics Research Institute, School of Engineering and Applied Science, Aston University, Birmingham, United Kingdom

The municipal wastewater treatment in a sustainable context requires a smart technology in which an optimal combination of the ecological status and energy demand can be achieved. The integration of electron conductive materials into a traditionally constructed wetland (CW) has been ... Read More

Predictive Model for UV Light Irradiation and PCO Reaction Kinetics in a Photocatalytic Reactor

S. Denys [1], J. Roegiers [1], J. van Walsem [1],
[1] University of Antwerp, Antwerp, Belgium

A novel type of photocatalytic reactor, i.e. parallel flow tube reactor (PFTR) is presented for the degradation of indoor air pollution with UV-light. A Multiphysics model was developed in COMSOL Multiphysics® to predict the steady-state behavior under different inlet concentrations and ... 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

Iron Ore Sintering Process Model to Study Local Permeability Control

Y. Kaymak [1], T. Hauck [1], M. Hillers [2],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany
[2] Shuangliang Clyde Bergemann GmbH, Ratingen, Germany

The iron ore sintering process prepares fine iron ore for the blast furnace process. A mixture consisting of iron ore, coke (fuel) and additives is ignited at the top and air is sucked from below to move a combustion front down through the bed. Most of the sintering plants use ... Read More
