Transition from the fossil-based to the bio-based chemical industry presents a global pro-

cess occurring in the context of sustainable development of our planet. Although the pro-

cess itself is inevitable and irreversible, the vast majority of researchers working in the field

agree that the pace at which it proceeds is still far from satisfactory. The essence of the

fossil-to-bio transition lies in fact in the successful generation of commercially viable feed-

stock-process-product triangles that offer clear benefits to the stakeholders concerned

(farmers, industry, governments, end-users, consumers, etc.). Unfortunately, for the time

being many of those triangles still appear a kind of “Penrose Triangles” described by Li-

onel and Roger Penrose as “impossibility in its purest form”. What challenges need to be

met and what questions need to be answered in order to make more of those triangles via-

ble? The Faraday Discussion “Bio-Resources: Feeding a Sustainable Chemical Industry”,

organized by the Royal Society of Chemistry and held on 19-21 June in London, debated the

latest developments in science and technology in that area. I had pleasure and honour to

act as the Closing Remarks Lecturer of that conference.

Challenges related to the devel-

opment of viable bio-based pro-

cesses, which differ them from

the oil- and gas-based manufac-

turing, include, among other

things, feedstock diversity and

variability, diversity of processes

and operations, ways oftrans-

porting feedstocks, regionaliza-

tion of feedstocks and markets,

and susceptibility to the force of nature. The Faraday Discussion not only did address many

of those challenges but also demonstrated new opportunities which should lead to novel,

commercially attractive concepts. Electricity-based technologies that build on Michael Far-

aday’s scientific legacy belong to such opportunities. On the long term, electricity is des-

tined to play the key role in process industries, as a fully renewable, widest available and

most flexible form of energy. This holds also for the fossil-to-bio transition where energy

consumption is presently one of the most important issues. Bioprocesses are often highly

energy-demanding and energy cost significantly affects process economy. The bio-based

industry utilizing fossil energy will never be really “green” and a gradual shift to cheap, re-

newable electricity as the primary energy source is needed. On the long term, such a shift,

along with the introduction of modularity in plant design should bring a dramatic change in

the bio-process economy. Future bio-processing plants will be modular and green electrici-

ty-driven. Such evolution will further help converting the “Penrose” triangles of the fossil-

to-bio transition of today into viable feedstock-process-product solutions of tomorrow.

First Book on Intensfication of Bio-Based Processes

P A G E 4 I S S U E 1 5

Process intensification (PI) is commonly mentioned as one of the most promising development paths for the chemical processing industry and one of the most important progress areas for chemical engi-neering research. While remaining a hot topic, bioprocessing still poses various important techno-economic and environmental challenges, such as product yields, excessive energy consumption for separations in highly watery systems, batch operation or the downstream processing bottlenecks in the production of biopharmaceutical products. Many of those challenges can be addressed by applica-tion of different process intensification technologies discussed in the world’s first book dedicated to Process Intensification in bio-based manufacturing, published in the Green Chemistry Book Series by the Royal Society of Chemistry. The book that will appear in the beginning of 2018, provides a com-prehensive overview of modern process intensification technologies used in bioprocessing. It in-cludes twenty three chapters written by the leading experts in the field and focusses on four different categories of bio-based products: bio-fuels and platform chemicals; pharmaceuticals, cosmetics and fine chemicals; food products; and advanced materials. Each part of the book covers various intensifi-cation aspects of the processes concerned, including (bio)reactor intensification; intensification of separation, recovery and formulation operations; and process integration. The book is aimed as a source of up-to-date information for researchers and industrialists working in chemical engineering, biotechnology and process engineering.

Course material on Industrial Crystallization P A G E 5 I S S U E 1 5

In 2015 the book “Industrial Crystallization – Fundamentals and Applications” by Allison Lewis, Mar-celo Seckler, Herman Kramer and Gerda van Rosmalen, appeared at Cambridge University Press. This text book provides the reader with a comprehensive overview of industrial crystallization. New-comers in the field will learn all of the most important topics in industrial crystallization, from key concepts and basic theory to industrial practices. Real world case studies are also provided, as well as new industry-relevant information, making this is an ideal resource for industry practitioners, stu-dents, and researchers in the fields of industrial crystallization, separation processes, particle synthe-sis, and particle technology.

Based on this text book, the authors developed course material in the form of separate power point presentations each covering one of the 14 book chapters. To stimulate the implementation of crys-tallization lectures in the education of engineers, we make this course material available to academic staff who would like to teach their students more about industrial crystallization on the basis of this book.

Open Technology grant for Johan Padding: Multi-scale understanding and control of spray drying processes

P A G E 6

The NWO Applied and Engineering Sciences (TTW) has awarded a grant of 655 kEuro to investigate the microscopic processes relevant for the drying of complex dispersions. Three groups will work on this exciting topic: the Food Process Engineering group in Wageningen (Maarten Schutyser), the Prod-uct and Process Engineering group in Delft (Ruud van Ommen) and our IRS group (Johan Padding). A new PhD student, Stephan Sneijders, has recently started working on the modeling aspects.

Spray drying is a widely adopted technology in food industry to make stable agglomerated powders. Despite its widespread use, the operation and design of spray dryers is usually obtained by trial-and-error approaches as the underlying physical phenomena related to particle morphology and agglomera-tion behavior (see figure) are not well understood. Therefore, a joint consortium of three groups aims at developing a better understanding of the drying kinetics and agglomeration of particles during spray drying. The approach chosen is multidisciplinary and includes experimental work involving well-defined droplet drying and agglomeration studies, soft matter theory development and numerical modelling. The research aims at mechanistic-based scaling rules that can be applied by the participating industrial users to better steer powder functionality while decreasing energy consumption and develop next gen-eration compact spray dryers.

PhD Defense of Javier Fernandez: Application of microwave plasma technology to convert CO2 into high value products

P A G E 7

Javier Fernandez was born in Valladolid, Spain. He was awarded as one of the best students of the year (2006) in high school by graduating within the top 5%. In 2012, he completed his M.Sc. degree in Chemical Engineering at Valladolid University (Spain). He graduated in the top 10% of his year. He has broad experience as a R&D engineer, mostly focused on the production of liquid fuels through innovative and sustainable technologies. He has worked on projects such as (1) the design of a pervaporation unit, based on membranes, to separate butanol from acetone-butanol-ethanol (ABE) mixture as an alternative to distillation, and (2) the start‐up and optimization of an ammonia fiber expansion pilot plant to pretreat wheat straw for the production of ethanol. Moreover, he ex-plored a new approach to produce MCM-41 for the encapsulation of ibuprofen by ultrasound-assisted supercritical CO2 during his stage at Ruhr University of Technology in Germany (2011-2012). He joined Delft University of Technology (March 2013) as PhD researcher to work on the application of microwave plasma technology to convert CO2 into high value-added products. This project was part of a large European consortium (ALTEREGO) that empowered the development of novel forms of energy for efficiently intensified chemical manufacturing. On November, 16th 2017, Javier successfully defended his PhD at Delft University of Technology. He is currently working at Hexion. The thesis can be downloaded from: https://repository.tudelft.nl/islandora/object/uuid:bed854a8-e4bc-4d23-b90c-00d68c5f6517/datastream/OBJ/download

Retirement Herman Kramer By Antoine van der Heijden

P A G E 8

On the occasion of the retirement of Herman Kramer after a career of 30 years in industrial crys-tallization at the Delft University of Technology, a Farewell Symposium was organized for Herman on June 16, 2017. The Symposium was attended by 80 participants.

Herman received his MSc degree in Molecular Science from the Agricultural University Wa-geningen in 1980. He continued with a PhD research study in biophysics, resulting in his PhD thesis “Structural aspects of energy transfer in photosynthesis” which he defended at Leiden University in 1984. After a two-year position as a scientific researcher at the Netherlands Organization of Ap-plied Scientific Research (TNO), he joined the industrial crystallization group at the TU Delft in 1987, first as a post-doc (1987 – 1992), then assistant professor (1992 – 1997) and finally associate professor (1997 – 2017). During his academic career Herman focused on many different crystalliza-tion topics, for instance a thorough understanding of processes like transient effects in continuous crystallization, primary and secondary nucleation, crystal growth, control of primary nucleation us-ing pulsed laser techniques, monitoring and control of particle size and shape, membrane-assisted crystallization, airlift crystallizer and the application of process intensification techniques, like mi-crowaves, in crystallization. Furthermore, Herman has been a member of many committees / working parties on crystallization and he was an active (board) member of the Dutch Association for Crystal Growth.

During the Farewell Symposium several invited colleagues from academia and industry shared per-sonal views on their close cooperation with Herman during the past 30 years and presented results of their current scientific work. Zoltan Nagy (professor of Chemical Engineering, Purdue Universi-ty, USA) gave a presentation on “Recent advances in the model-based control of crystallization systems”. Herman’s former TU Delft colleague Joop ter Horst (since 2014 professor of Industrial Crystalliza-tion, University of Strathclyde, Scotland) continued with a presentation on “Primary and secondary nucleation in continuous crystallization”. Richard Lakerveld (Hong Kong University of Science and Technology, Hong Kong), one of Herman’s former PhD students, shared his views on “Continuous pharmaceutical crystallization: a lot of science, and a bit of art”. The last invited speaker was Rob Geertman (Janssen Pharmaceutical Companies of Johnson & Johnson, Belgium) with a presentation on “Crystallization as start of the formulation process: it is all about making the right particle”.

The Symposium was closed by a presentation of Herman, who shared his view on the develop-ments in the field of crystallization to which he has significantly contributed over the past three decades and a personal outlook on future developments in this area. The title of his farewell ad-dress was: “Modelling design and operation in industrial crystallization processes; developments and future prospects”.

Herman may look back on a very fruitful and successful career of 30 years in industrial crystalliza-tion, where he guided, inspired and encouraged many BSc, MSc, PhD students and co-workers. We now wish Herman all the best in his retirement! Much more time will be available for his family and grandchildren as well as for his hobbies like cycling and skating. We are very fortunate that Herman has decided to come back to Delft once a week to continue the guidance of a few PhD students who almost finished their theses. In this way we will be able to still take advantage of Herman’s ex-pertise and skills in the near future!

Peng Yan On 1st of September, I began my Joint PhD study in the Chair of Intensified Reac-tion and Separation Systems, P&E Department within the Faculty of 3mE. I am working under the supervision of Prof. dr. Andrzej Stankiewicz. The main focus of my research is travelling microwave reactor design by modelling and simulation. This concept, based on endothermic gas-solid catalytic reaction, aims for sustaina-ble process by using electricity instead of conventional heating and makes full use of microwave selective heating and special molecule-catalyst interaction for bet-ter selectivity, conversion and energy efficiency.

I was born Oct. 1990 in Heze, China. I obtained my Bachelor’s degree in Chemical Engineering from Nanjing Tech. University, China, with my graduation project in process design and simulation by AS-PEN Plus (Jun. 2013). I moved to Tianjin University in Sept. 2013 for Master-PhD continuous study working on the national key project of “The theoretical study of green distillation process”, under the supervision of Prof. Xingang Li, the Director of National Engineering Research Center of Distillation Technology. My research work is “Surface wettability-enhanced hydrodynamics and novel equipment design for reactive distillation”. The main results of my work are 1) developing the method to fabricate foam column trays with special wettability, ranging from hydrophilic to hydrophobic and superhydro-phobic; 2) hydrodynamic investigation and clarifying multiphase flow mechanism for the above column trays; 3) reactive distillation column design for gas-phase catalytic reaction based on above investiga-tion; 4) finally expanding the design concept of special wettability to conventional distillation column trays and meanwhile putting forward a new design: Janus tray.

Rong Fan On 1st September I began my PhD studies in the Chair of Intensified Reaction and Separation Systems, P&E Department within the Faculty 3mE. I am working under Dr.ir. JT (Johan) Padding’s supervision. The main focus of my research is to use Sto-chastic Rotation Dynamics to investigate the coupled convection-diffusion-reaction mechanisms taking place in boundary layers and in structured porous media. I was born in 1990 in Lanzhou, China. I got my bachelor degree in chemical engineering from Xiamen University, China. During my bachelor, I was in the XMU’s team of the iGEM (International Genetically Engineered Machine) contest. I did my master in the department of chemical engineering and chemistry at Eindhoven Uni-versity of Technology. In my master thesis, ‘Numbering-up of capillary microreactors for biphasic pho-tochemical processes’, I worked on the key influencing factors on the numbering-up of continuous-flow photomicroreactors for liquid-liquid systems by experiments, including the hydrodynamics, heat and mass transfer limitations.

Stephan Sneijders I finished my Bachelors and Masters (cum laude) in Chemical Engineering at Eind-hoven University of Technology in February 2017. During my Masters I became interested in the fields of numerical methods, computational fluid dynamics, and computational physics. This interest resulted in my master thesis called: “Direct numerical simulations of Flow and Heat Transfer through Realistic Computer Generated Solid Foams”. Furthermore, during my Masters I did an industrial in-ternship at Refineria Isla Curaçao; an oil refinery located on one of the Dutch

Caribbean islands close to Venezuela. A couple of months after finishing my Masters I started my PhD in the IRS group under direct supervision of Johan Padding. During my PhD I will work on modelling the drying of complex dispersion droplets, e.g. drying of milk droplets. I’m also very interested in the fields of process optimization and queueing systems. Occasionally I like to work on small projects related to those subjects in my spare time. Next to puzzling on queuing systems and optimization problems I like to spend my spare time playing drums in my band, playing soccer on Sunday mornings, and going to the gym now and then.

Elyas M. Moghaddam

I (an engineer by profession) fulfilled my higher education degrees, BSc. (2006) and MSc. (2008), both in the field of Chemical Engineering at the Ferdowsi University of Mashhad and Iran University of Science & Technology, respectively. My major specialization during the graduate degree centered on the Gas Processing Industry, viz. design of gas refining processes, and at Master level, on Process Modelling, Simu-lation and Control, where the emphasis of my research centered on investigation of transport phenomena in fixed bed catalytic reactors. I commenced (2011) PhD research on Design As-pects of Tubular Fixed Bed Catalytic Reactors at LSB University, UK. My PhD program had been pur-sued under the supervision and guidance of Professors E. A. Foumeny and J. F. Missenden with the re-mit of assessing the influence of tortuous structure on flow hydrodynamics and heat transfer typified by effective lumped parameters in tubular fixed bed arrangements. I joined TU Delft as a PhD candidate in October 2017 in the Department of Process and Energy to fulfill my PhD under the supervision of pro-fessors A. Stankiewicz, E.A. Foumeny (external co-promoter) and Dr. J. Padding. As part of the re-search remit, I concentrate on the study of the influence of packing structure of shaped catalyst pellets on the behavior of flow field and lateral heat transfer using a novel computational approach, entitled coupled Rigid Body Dynamics and Computational Fluid Dynamics.

As far as industrial relevance is concerned, my achievements secured appropriate positions for me (e.g. senior researcher and process lead engineer) with famous research institutes as well as engineering consultant groups in Iran, such as Research Institute of Petroleum Industries (RIPI), the largest research center in Iran, Petroleum Institute of Tehran University and Jahanpars Engineering group. To this end, I have so far managed to publish a number of industrial and research reports and publications, covering CFD simulation of production of γ-alumina in gas-solid moving beds, CFD simulation of the deposition of pharmaceutical agents in human respiratory system, software preparation for process and mechani-cal design of oil desalting system, and design of around 100 fixed and rotary equipment that have al-ready been installed and operational in several refineries in Iran south oil/gas fields.

Hakan Nigar

I completed my Bachelor's degree in Chemical Engineering (honor student) at the University of Ankara, Turkey. During the degree, I moved to Spain as an Erasmus Ex-change student for two semesters. Due to the experience that I gained and relation-ships that I built in Spain, I decided to go back there for my postgraduate education, especially to continue my study to gain applied knowledge and experiences by an aca-demic research in Nanotechnology and Nanoscience. Then, I received my M.Sc. in Nanotechnology in 2012, and my Ph.D. in Chemical and Environmental Engineering (Cum Laude) in 2017 from University of Zaragoza, Spain. As you know that studying abroad is a challenging and exciting experience and it definitely improves one’s knowledge and academic performance. Hence, I continue my academic journey now as a post-doctoral researcher in the IRS group of the Process & Energy department at TU Delft. My research interests lie energy efficiency of the heating systems and designing efficient and sustainable methods for adsorption-based catalytic pollutant control systems and employing the microwave heating as an alternative, energy efficient, cost-effective method. I am also experienced in simulation and model-ing of multiphysics processes including electromagnetic waves, fluid dynamics, heat-mass transfer and chemical kinetics.
