Developing energy efficient separations across a range of industrial applications
Separations accordion widget
Theme overview and objectives
Our main objective is to develop energy efficient separations across a range of industrial applications using novel materials and synthesis, chemical analysis and systems and process design. By integrating chemical and biochemical processes with solutions to their separations challenges we create tailored and transferrable separations solutions for a multitude of scenarios. These include membrane-based separations in the gas and liquid phase, CO2 removal from complex effluent streams, and waste refining and trace element removal from complex streams.
Methods and capabilities
We utilise a wide variety of technologies to implement these goals. Our characterisation expertise enables us to examine structured materials, custom liquids, and porous solids while focusing on their thermophysical, sorption and performance properties, extending across synthetic and natural materials. We utilise advanced synthetic techniques and materials processing to develop materials suitable to a variety of challenging environments. We remediate difficult waste streams (CO2 from gas streams, waste water, trace heavy metal removal from solid and liquid waste streams) to enable further processing and valorisation of these resources.
Pedal-powered water purification using membranes
The Livingston Group at Imperial Festival 2016
The Livingston Group from the Department of Chemical Engineering at Imperial College London perform research on the fabrication and application of molecular separation membranes with the overarching aim to reduce energy costs and increase efficiency of chemical separations in industry.
At Imperial Festival 2016 the group demonstrated the power of membranes to purify water by comparing the bicycle driven energy needed to purify water through distillation vs membrane purification ... the membrane bike won!

'Crumpled' filter has potential to slash energy consumption
Imperial researchers from the Department have developed advanced membranes.
Engineers have developed an ultra-thin, super-strong membrane to filter liquids and gases, with the potential to cut energy consumption in industry. Find out more
Why paper-thin filters could be key to cutting emissions
Audio story with Professor Andrew Livingston on his group's latest membrane research
In this audio story, Professor Andrew Livingston gives listeners the low-down on membranes and how they are used to make many products we need in our daily lives. He also carries out ‘frontier’ research, where he is pushing the boundaries membranes usage forward. He and his team have developed membranes that are made from nanoscopic, twisted, fusilli-like material. He talks about how industries such as the oil and gas sector could be the big winners by adopting this technology, which in the future could cut their emissions and save energy.

Dr Patrizia Marchetti on membrane research
Her research activity covers membrane-based separation processes
Patrizia Marchetti, research associate, Imperial College London – UK
Patrizia holds a BSc (2007) and MSc (2009) in chemical engineering from the Politecnico of Milan, Italy. She obtained her PhD degree under Marie Curie Actions from Imperial College London (2013). Her work at Imperial has been sponsored by Lanxess, a German polymer and specialty chemicals group, and more recently by GSK.
Her research activity covers the fields of pharmaceutical downstream, peptide chemistry, membrane-based separation processes, functional and nano-scale materials and advanced nanoparticle assembly, transport and process modelling.
Patrizia’s research achievements have resulted in several research articles and reviews in international scientific journals, two book chapters, a patent application and numerous presentations at renowned international conferences.
