Laurence Weatherley is the Albert P Learned Distinguished Professor of Chemical Engineering at the University of Kansas. Weatherley received his PhD from the University of Cambridge in Chemical Engineering for research on ion exchange kinetics in macroporous resins. He then worked in the United Kingdom as a practicing chemical engineer in the nuclear industry for 6 years before joining Heriot Watt University in Edinburgh, Scotland where he was tenured faculty member in Chemical and Process Engineering for 13 years. In 1992 he was appointed to an endowed chaired professorship at the Queens University of Belfast (QUB), UK, the DuPont Chair of Process Engineering. In 1996 he was appointed to the leadership position of Assistant Provost for Research in the College of Engineering at QUB. In 1998 he accepted the position as the established Chaired Professor of Chemical Engineering and Head of the Department Chemical and Process Engineering at the University of Canterbury in New Zealand. He took his current role as Chair of Chemical Engineering at the University of Kansas in 2004. Dr Weatherley’s research interests are in the area of liquid-liquid systems, process intensification, water treatment and enzymatic biotransformation. He has published over 200 research papers, articles, conference papers and other contributions. He has extensive teaching experience in chemical engineering core subject including design, mass transfer, fluid mechanics, and chemical reactor engineering. For nine years until January 2010 he was Executive Editor of a leading international research journal, the Chemical Engineering Journal where his responsibilities covered the environmental chemical engineering section of the journal. Dr Weatherley is a chartered professional engineer (UK), is a Fellow of the Institution of Chemical Engineers, United Kingdom, and is a Fellow of the Institution of Professional Engineers of New Zealand. He has over fifteen years experience as a Head of Department / Chair taking responsibility for the management and direction in two university departments. He also has experience in the setting up of international opportunities for undergraduate students and has also led a highly successful international research collaboration with the Lodz University of Technology, Poland.

Research

My research interests are in the area of environmental process engineering with a focus on the intensification of chemical reaction and separation processes involving liquid mixtures and solid/ liquid mixtures. Intensification involves development of small, highly efficient process equipment which reduces plant footprint, reduces the inventory of hazardous solvents in chemical processes, and provide opportunities for the application of new green chemistry. Environmental process engineering is not only focused on cleaning up waste but also on innovations for cleaner, energy efficient, safer and more intensive chemical processes with the goal of avoiding generation of waste. Environmentally friendly development of new chemical processes based on feed-stocks such as cellulosic biomass, soy, and shale gas which are abundant in Kansas, require such innovations. Recent personal research projects include development of new miniaturization technology for biodiesel synthesis based on high gravity fields, optimization of biogas production from blended agricultural and municipal wastes, application of natural zeolites in combination with bacteria for enhanced waste water treatment, and the development of new intensive processing based on electrostatic spraying in liquid-liquid systems. To amplify on the latter, an everyday example of a liquid-liquid system is in a bottle of vinaigrette dressing where there are two immiscible liquids – a light oil phase and a heavy aqueous (vinegar phase). The efficient mixing and separation of liquid-liquid mixtures are of great importance in many industries, including oil and petrochemicals, pharmaceuticals, biodiesel, nuclear fuel processing, and metal extraction. We have significantly advanced understanding of the physical factors and the mathematics which describe drop size, spraying phenomena and drop motion, together with diffusional phenomena when two immiscible liquids are contacted in an intensive environment. The research is underpinned by an understanding of the fluid dynamics when liquid-liquid mixtures are processed under intensive conditions including high gravity or in the presence of high voltage electrical fields.  Our work in this area provides computer simulation tools for the design and scale-up of novel equipment operating under these conditions. These tools enable low cost design innovation, optimization, and will reduce risks in full scale application.

My areas of research focus on several themes as follows:

Liquid-liquid Systems and Intensification

This research is concerned with the scale-up of intensive liquid extraction processes, focusing on fundamentals of drop motion behavior (as discrete drops and in swarms), modeling of mixing and mass transfer in liquid-liquid contactors; fundamentals of electrically charged drop motion in liquid-liquid systems; interfacial mass transfer, equilibria and drop behavior in biological product extraction systems; Spinning disk techniques for intensive liquid-liquid and gas liquid contact.

Enzymatic Catalysis

This research focuses on the process intensification of enzymatic biotransformation processes in two phase liquid systems and associated downstream separations. Applications include enzymatic modification of natural oils and fats via the production of fatty acids by hydrolysis. This approach is especially of potential value for splitting of sensitive triglycerides, unconjugated systems (which may undergo thermal degradation), hydroxylated fats and oils or polyunsaturated oils.

Ionic Liquid Solvents

Ionic liquid solvents; synthesis, physical property measurement, partition, spraying behavior and applications; new techniques and solvents for extractive whole cell biocatalysis using ionic liquids, toxicology studies; fundamentals of mass transfer and fluid dynamics in liquid-liquid systems involving ionic liquids for separations and for reaction; development of novel reactors and contactors for intensification of liquid-liquid and gas-liquid systems involving ionic liquids.

Ion-Exchange and Biological Treatment Processes

This research focuses on ion-exchange kinetics & equilibria in synthetic and natural ion- exchangers and on simultaneous ion-exchange and bioregeneration in zeolitic ion exchangers. Of special interest is the intensification of the supply of oxygen to aerobic microorganisms during  adsorption and bio-adsorption processes for waste water treatment and potable water pre-treatment, development of combined physical and biological separation processes, and the development of new adsorbents and exchangers based on natural materials. Optimization of biogas production from blended agricultural and municipal wastes is a recent theme developed in collaboration with the Lodz University of Technology, Poland.
