Job description

Postdoctoral researcher: Integrated model guided process optimization of steam cracking furnaces (IMPROOF)

Aim 
Evaluate theoretically and experimentally the potential benefit of applying high emissivity coatings, oxy-fuel combustion and 3D reactor designs in steam cracking furnaces.

Justification 
Steam cracking is one of the most energy intensive processes in the chemical industry. Although steam cracking technology is considered to be mature, the complexity of the process and the harsh operating conditions allow the implementation of technology developments towards substantial heat transfer enhancement. One of the main objectives of IMPROOF is to increase the energy efficiency of the radiation section of a steam cracking furnace, minimizing exergy losses. A key element to realize this is the use of high emissivity coatings manufactured and studied under real furnace conditions in the project. On the other hand NOx emissions can be reduced by the possible use of oxy-fuel combustion. Finally, the efficiency and selectivity can be improved by applying

Program 
Although the benefit of the application of high emissivity coatings is clear they are still rarely applied for steam cracking furnaces. Therefore IMPROOF will assess the results of the application of high emissivity materials on improved refractory materials on TRL5 and TRL6 level. These furnace redesigns of components and process tubes combined with CFD modelling will be a further multiplier for the potential benefit of IMPROOF. IMPROOF seeks to further demonstrate that also existing furnaces can be retrofitted to increase their performance. At the same IMPROOF will result in optimized resource and energy efficiencies, and also less pollutant emissions. A risk is that, as a result of improvements in the radiant section by coating various components with high emissivity products, the amount of heat released to the convective section will be reduced. This will necessitate a re-evaluation of the operation of the convective section which will prompt the evaluation of high emissivity products to improve heat absorption in this area as well.

Nowadays, there is an increased interest towards the development of oxy-fuel combustion, i.e. the process of burning a fuel using pure oxygen instead of air as the primary oxidant. One of the advantages of oxy-fuel combustion is the production of a highly concentrated stream of CO2, ready for capture and storage (CCS). Beside CCS, oxy-fuel combustion has other advantages, such as the possibility to significantly reduce the size of the combustor unit compared to that used in the corresponding air-fired combustion. Another essential question that will be addressed by IMPROOF is if the use of renewable fuels such as bio-gas or bio-oils is actually beneficial to be considered in steam cracking furnaces. Detailed kinetic models and CFD will be used to provide answers to all these questions.

Profile of the candidate

Applicants must possess a PhD in Chemical Engineering or related subject and a TOEFL certificate with a minimum score of 95(iBT) or equivalent. Relevant experience in the area of reactor engineering, kinetics, and/or computational chemistry is strongly recommended. Candidates must have a strong mathematical background and be willing to focus on obtaining quantitative rather than qualitative results.

How to apply

Any additional information can be obtained by contacting Guy.Marin@ugent.be. Any application should enclose a C.V., a one page justification of your interest and the e-mail addresses of at least two references.

  Mathematical Modelling in the Engineering Sciences and its scientists

Within this field of research, top-class scientists engage in the crosslinking between modeling, simulation and engineering. The research topic consists of three overlapping foci:

Mathematics

Mathematics and computer science represent a technology that is essential to engineers and natural scientists. Progress in relevant fields is therefore often dependent from computational mathematical modeling. Due to its focus on mathematical applications in engineering, Kaiserslautern attains a unique position.

Transfer

This focus researches via modeling and simulation solutions for problems in the following fields: transport processes, fluid dynamic and structure elastic processes, planning and decisions problems (e.g. logistics, engineering sciences, life sciences).

Engineering/Application

This research focus examines trendsetting materials classes and technologies, in which highly dynamical scientific and technical developments take currently place. An important feature of the research is the intensive crosslinking between experiment, modelling and simulation to ensure a reliable and efficient operation of facilities and systems.

Membrane Biology and Systems Biology and its scientists

Within this research topic, top-class scientists engage in the understanding of dynamic processes that happen within, at, or via biological membranes. Therefore, they use systems biology approaches to analyze the adaptation of protein- or lipid-compositions of membranes to changes in environmental conditions, fungal secretomes, or the exchange between intra- and extracelluar compartments.

Experimental methods are high-throughput technologies such as Mass Spectrometry, Next Generation Sequencing, Spectroscopy and imaging techniques. With regard to mathematics/informatics, algorithms are developed in order to handle and analyze the generated large data sets and mathematical models, involving several types of ordinary and partial differential equations, are set up in order to reveal the underlying biological mechanisms.

Optics and Material Sciences and its scientists

Within this research field, top-class scientists engage in research about the interactions of light, spin (magnetism), and diverse forms of matter. The cutting edge research topics are studied across the borders of the traditional disciplines of sciences and engineering introducing new connections between the fields.For advancing the research topics, the scientists contribute their expertise in quantum optics, applied optics, magnetism, surface physics, molecular and material sciences and benefit from the exchange of ideas. The scientists engaged in karema in this field are from experimental and theoretical physics, as well as physical chemistry. Their manifold projects range from basic research, e.g. Bose Einstein condensates all the way to technology-oriented research, like the development of novel data carriers.

New generation of high-resolution mapping techniques for studying the refractory phase of slow wave activity in the stomach

New generation of high-resolution mapping techniques for studying the refractory phase of slow wave activity in the stomach

 Project Description
Stomach contractions are governed by an underlying bio-electrical event known as slow wave activity. Slow wave dysrhythmias have been linked to a number of major digestive disorders. The recent development and application of high-resolution electrical mapping techniques has enabled critical advances in understanding normal and dysrhythmic patterns of gastric slow wave activity.A key hypothesis developed from these studies was that the refractory phase of gastric slow wave activity could be a significant factor in the initiation and maintenance of dysrhythmic patterns. This project will aim to develop a new generation of high-resolution mapping techniques for studying the refractory phase of slow wave activity in the stomach. It will focus on the following novel techniques:

1. A high-resolution multi-electrode mapping device that makes contact with the stomach and records monophasic electrical potentials. Our novel high-resolution mapping analysis techniques will be applied to reconstruct the sequence of the underlying gastric electrical activation.

2. Investigate the mechanisms involved in perpetuating gastric dysrhythmias. In particular, interventional approach such as selective ion blockers and pacing will be applied in an experimental model to assess electrical activation and recovery propagation.

3. Through our collaboration with Professor Jack Rogers at the University of Alabama at Birmingham (UAB, USA) and Faculty of Medical and Health Science at UoA, we will apply optical mapping techniques to the stomach. Optical mapping involves the use of voltage sensitive dyes and optical sensors to map electrical patterns, enabling analysis of repolarisation of gastric electrical activity with outstanding spatial and temporal resolution.

The candidate will have the opportunity to work with leading bioengineers and clinicians in extracellular mapping at the Auckland Bioengineering Institute and the University of Alabama at Birmingham (UAB, USA). You will devise, design, develop and construct novel electrode platforms and apply them in experimental studies. You will also be involved in developing and applying novel signal processing techniques to analyse and interpret findings. The findings will be used to define the mechanisms of the initiation, maintenance and termination of complex slow wave dysthymias recorded clinically.

Candidate requirements:

An ideal candidate should have interests in
1. device prototyping/development and electrode construction
2. experimental electrophysiology
3. signal processing, quantitative analysis and data presentation
4. engineering, physics and applied maths

Funding Notes

For eligible students funding is available as part of a Health Research Council grant

A combined computational and experimental approach to optimise band energies and stability of semiconductors for applications in photocatalysis

A combined computational and experimental approach to optimise band energies and stability of semiconductors for applications in photocatalysis

Project Description

Solid-state materials display various physical properties, such as thermoelectricity, photoconductivity, photocatalysis and superconductivity. These properties show a strong interplay with the electronic band structure of the material. Consequently, these properties can also be affected by the particle size of the material at the nanometre scale. The aim of this project is to use a combined computational and experimental approach to rationally optimise the band energies and morphology of semiconductor nanoclusters to improve their photocatalytic activity in water splitting. This will ultimately contribute to the development of sustainable energy carriers to reduce our dependency on fossil fuels.The proposed PhD project will start from the synthesis and characterisation of a range of nanoclusters. The effect of the supporting matrix and how it influences the water-splitting photocatalytic reaction will be assessed computationally by Density Functional Theory (DFT) calculations. Insights obtained from DFT calculations will serve to rationalise experimental observations and improve the design of nanoclusters, such as metal oxides, nitrides and chalcogenides.The PhD student undertaking this project will work on an exciting interdisciplinary research area under the supervision of Dr Jiayun Pang and Dr Petra Szilagyi. During the PhD, the student will receive training in both experimental (electron microscopy, optical spectroscopy, etc.) and computational (DFT calculations) techniques, a skill combination increasingly valued by the research community and industry employers.

Funding Notes

Bursary available (subject to satisfactory performance):

Year 1: £14,553 Year 2: In line with RCUK rate Year 3: In line with RCUK rate

In addition, the successful candidate will receive a contribution to tuition fees equivalent to the university’s Home/EU rate, currently £4,195, for the duration of their scholarship. International applicants will need to pay the remainder tuition fee, currently £8,305, for the duration of their scholarship. This fee is subject to an annual increase.
