The Science Behind a Granule: 'A life Story'

Professor Agba D. Salman, The University of Sheffield

Portrait AgbaWet Granulation is a size enlargement process where powder particles are bonded together using a liquid, which can be poured, sprayed or melted into the powder mass. Granulation is an important processing step in many industries, perhaps most notably in the, pharmaceutical and food industries. Historically, process and product development has taken place on a case by case basis, with significant costly trial and error required. There is now a move forward to take this ‘black art’ approach towards a more science based engineering design methodology, with a view to develop a ‘granulation theory’ and a comprehensive multi-scale model. In order to do this it is necessary to employ various experimental techniques across all the length scales; micro-, meso-, and macro-. Some of the techniques being further developed; such as particle image velocimetry (PIV), High Speed Imaging, Thermal Imaging, X-Ray Tomography, Visual On-line sizing (VOS) and DEM modelling, and their application from drop-powder and drop-granule interaction and evolution of granule structure at the micro-scale, to intra-granulator powder motion and collision rates, binder distribution at the macro-scale, will be introduced. 

About: Agba D. Salman is a Professor of Chemical Engineering at the University Sheffield. He has published more than 300 papers and has led more than 80 collaborative research projects with range of industries; from food, pharmaceutical, to detergent and fertilisers on understanding the science behind industrial granulation processes allowing formulators to design processes, which deliver better products for consumers. He has also organized 9 international meetings on Granulation and edited 16 special issues of international journals, and two Handbooks on Granulation and Particle Breakage. ​


Back to the future: Distillation and other separations in the era of bio, info and process intensification

Professor Andrzej Górak, TU Dortmund University

Portrait GorakDistillation and absorption are the main work horses of the chemical process industries, but are highly energy intensive processes: Distillation of hydrocarbons from crude oil consumes energy equivalent to the total energy consumption of the United Kingdom in 2014; energy sufficient to power roughly 40 million homes is needed to separate cyclic hydrocarbons through distillation worldwide; and the energy sector emits more than 30 gigatons of CO2 worldwide, equivalent to about two thirds of total CO2 emissions, which must be recovered through efficient absorption/desorption systems.

This lecture will show how efficient distillation and absorption technologies can, and must, contribute to solving the global challenges we are facing today, but more importantly, the challenges future engineers will be facing in the coming decades. Some examples that will be considered:

  • enzymes in distillation and absorption
  • intensification of absorption and distillation in modular devices or centrifugal fields
  • digitalization and additive manufacturing for efficient separations.

About: Professor Andrzej Górak, chemical engineer by training, obtained his Ph.D. from TU Lodz in Poland. He worked a researcher at Henkel KGaA in Düsseldorf and became professor and the Chair of Fluid Separation Processes at TU Dortmund University, Germany in 1992.

Opportunities and Obstacles in Establishing and using Digital Twins

Prof. Dr.-Ing. Rainer Stark, TU Berlin & Fraunhofer IPK

Portrait StarkThe digital Twin technology has been recognized during the last years to provide new enablers for technical and business processes. Unfortunately, the term Digital Twin still is used with different meanings since IT vendors only loosely followed a stricter understanding and hence partially misused it for marketing purposes. 

This presentation will, therefore, deliver a clear definition and will explain the difference to a Digital Master and a Digital Prototype. Furthermore, a theoretical foundation will be given for the target behavior dimensions of Digital Twins as well as a first explanation of the critical design elements of Digital Twins. 

Prof. Stark will also give an insight into the different kind of Digital Twins which have been established within the research labs and Industrie 4.0 labs at the IWF of TU Berlin and the Fraunhofer IPK. The presentation will also tackle the as-is situation in industry and the outlook for the challenges and opportunities ahead.

Joining in non-rigid variation simulation to support a Digital Twin for geometry assurance

Kristina Wärmefjord, Associate professor, Department of Industrial and Materials Science, Chalmers

Portrait Kristina WärmefjordA digital twin for geometry assurance can be used for real time optimization and improvement of the product and production processes. To be able to rely on the digital twin, as many as possible of the factors affecting the product in reality need to be included in the simulation model. This presentation focuses on how different aspects of joining can be included in a digital twin for geometry assurance and the effects on accuracy. Examples from automotive and aerospace industry will be presented. 

About: Dr. Kristina Wärmefjord took her PhD 2011 and works within the research group of “Geometry Assurance & Robust Design”.

Digital twins in the engineering tool chain - automatic update of geometrical changes

Knut Åkesson, Professor, Automation, Department of Electrical Engineering, Chalmers

A digital twin needs to updated and synchronized with changes in the production system, this includes changes to both the software and the hardware. This is today largely a manual process and a common situation is that the digital and physical systems are synchronized during the initial virtual commissioning phase but tend to deviate away from each other over time. With synchronized we mean in this context that the digital models of both the software parts and the hardware parts are useful abstractions of the physical system. Not having the systems synchronized significantly, decrease the value of the digital twin and thus it is important to establish new automated methods to keep the physical systems and the digital twin synchronized with each other. In this presentation, we show how recent results from computer vision and artificial intelligence can be used to synchronize geometrical models. This includes approaches to build point-cloud models from multiple camera images, recognizing objects and estimation their 6D-pose. We present some initial results and some challenges that will be addressed in a new research project.

About: Knut Åkesson is a professor in Automation at Chalmers. He received his PhD in Automatic Control from Chalmers in 2002, and his Master of Science in Computer Science and Engineering from Lund University in 1997.

Recently he has also started to do research on machine learning and computer vision techniques with applications for automated production systems. 


Digital twins in the engineering tool chain - analysis and optimization of the control functions

Kristofer Bengtsson, Dr., Automation, Department of Electrical Engineering, Chalmers 

Portrait Kristofer BengtssonThe engineering work is often about creating different types of models. The current trend when developing automation systems is to create highly detailed and complete virtual models that can be used from early design to final virtual commissioning. However, the developed models are usually not kept up-to-date with the real system or used during production. This talk will therefore present the latest research about reusing the digital models as digital twins to optimize and analyze the running system, for example to reduce the wear and tear or save energy. Automated algorithms to identify changes in the control functions in the real systems that keeps the digital models in sync with the real system, will also be presented.

About: Dr. Kristofer Bengtsson received his Ph.D. degree in Systems and Control from Chalmers University of Technology in 2012.

SESSION 2: Simulation as a tool for chemical engineering​

Simulations facilitate development of sustainable hygiene products

Charlotta Hanson, Senior scientist, Adjunct professor, Essity Hygiene and Health AB

Portrait Charlotta Hanson Simulations can be used in many ways to facilitate the development of sustainable hygiene products. Many hygiene products are made for handling of fluids. An essential element in fluids handling is the absorption of liquids by means of porous structures. Models of fluid transfer in porous structures can be used to properly adjust the function of an absorbent, to optimize the manufacturing process of the porous structure or to investigate how to improve the microclimate of the product for the comfort of the user. Simulations can be used to speed up the development process, to set the proper route in trouble shooting or for efficient knowledge transfer. Models are compact storages of knowledge that can be used in the communication between the many players involved in the complex life cycle of a hygiene product, all acting to optimize the processes involved in the creation of sustainable solutions. 

About: Dr. Charlotta Hanson is Senior Scientist, Essity Hygiene and Health AB and Adjunct Professor at Chemistry and Chemical Engineering, Chalmers University of Technology. She has a PhD in Chemical Engineering on the properties and quality of lime from the lime mud reburning process in the sulphate pulp mill. She has been working for twenty five years in industry, specializing in the science behind fluid absorption in hygiene products. The common denominator for the studies at Chalmers and at Essity has been porous structures; their characteristics and properties and how they influence and are influenced by different processes.
