Biography

​Andrew Livingston (AGL) was born and bred in Taranaki, New Zealand and studied Chemical Engineering in NZ. Following graduation, he worked for 3 years at an NZ food processing company and then in 1986, started PhD at Trinity College, University of Cambridge. Upon finishing his PhD in 1990, he joined the Department of Chemical Engineering at Imperial College. At Imperial, he has carried out research into membrane separations, biotransformations, chemical and separations technology. AGL leads a research group of 20 PhD students and Post-Docs, with current research interests in membranes for molecular separations in liquid systems, and especially organic liquid systems, including membrane formation, imaging of membranes and characterisation of their structural and functional performance, engineering and design of separation processes, and applications of membrane separation to manufacturing.

AGL was made full Professor in 1999, has published over 250 refereed papers and been granted 15 patents in chemical technology. Awards include Junior Moulton Medal, Cremer and Warner Medal of IChemE, and Silver Medal of Royal Academy of Engineering. Elected a Fellow of the Royal Academy of Engineering in 2006, he served as Head of Department of Chemical Engineering at Imperial College from 2008-2016. From October 2016 he has been the inaugural Director of the Barrer Centre at Imperial College, focussed on breakthrough research into separations materials, science and engineering.

In 1996, AGL founded Membrane Extraction Technology, a spin-out company which evolved to manufacture solvent stable Organic Solvent Nanofiltration (OSN) membranes. On 1 March 2010 MET was acquired by Evonik Industries of Essen, Germany, and continues in business as Evonik MET Ltd., a part of the Evonik Fibres and Membranes Business. AGL continues working with Evonik MET as the Chief Innovation Officer.

Advanced Polymer Membranes for Molecular Separations in Organic Liquids

​​​​Membranes have had a huge impact in molecular separations in aqueous systems, especially desalination. It is generally accepted that 40-70% of capital and operating costs in chemical and pharmaceutical industries are dedicated to separations; and a substantial fraction of this cost is related to processing of organic liquids. Membrane technology has the potential to provide game changing alternatives to conventional concentration and purification technologies such as adsorption, chromatography, liquid extraction, evaporation and distillation, through Organic Solvent Nanofiltration (OSN) [1]. The membranes must offer resilience in organic environments, display attractive selectivities, and have good permeance. Ideally they should also be resistant to physical aging and fouling under use.
This presentation will focus on research into advanced membranes for OSN and their applications. Ultra-thin polyamide films (sub-10nm) have been formed by interfacial polymerisation and then used to fabricate composite membranes. These can be activated by a strong solvent, and have excellent permeance and high rejection [2]. It has been found that the aging of these composite membranes derives from properties of the support membrane rather than the thin film itself. Intrinsic microporosity can be introduced into the ultra-thin polymer films through selection of contorted monomers for interfacial polymerisation. These intrinsically microporous polymer nanofilms provide higher interconnectivity of pores and greater permeance than films obtained from planar monomer systems [3]. Further, new integrally skinned asymmetric membranes capable of filtration of solutions of DMF and other solvents at over 140oC have been developed by taking advantage of the properties of poly-ether-ether-ketone (PEEK) [4].
Finally, some applications and expected future developments of OSN will be introduced [5], and the potential for ultra-high permeance membranes to impact on actual molecular separation processes will be discussed, including the relative merits of selectivity, permeance and stability [6].
