Professor Barry Crittenden

BSc, PhD, CEng, FREng, FIChemE, FHEA, LRPS

Profile

Professor Barry Crittenden studied for a BSc and a PhD in Chemical Engineering at the University of Birmingham. He has worked for the UK Atomic Energy Authority, the MoD and M W Kellogg, and has worked at the University of Bath since 1973.

He is a Lead Accreditation Assessor for the Institution of Chemical Engineers and he has extensive experience as an External Examiner for undergraduate degrees in chemical engineering in UK universities.

Barry was elected to Fellowship of the Royal Academy of Engineering for his research and development of new processes, especially those that incorporate advanced separation processes.

Research

The overall thrust of Barry’s research has been to facilitate business performance improvement concomitantly with environmental performance improvement. This includes energy management as a component part of environmental management.

Principal technical areas of study include selective adsorption, ceramic membranes for gas separation, and hydrocarbon fouling, with applications in pollution prevention, clean technology, pollution control, waste minimization and energy efficiency.

Barry has over 200 publications arising from over 80 research grants and contracts with a total value in excess of £12m, and he has supervised over 20 PhDs and MPhils.

Barry's research on fouling of oil refinery heat exchangers is focussed on controlling the problem, particularly through the determination of the thresholds of surface temperature and surface shear stress at which fouling is likely to commence.

This practical problem is of immense importance, both practically and financially, to the operation of modern oil refineries worldwide which, increasingly, are being faced with the prospect of having to use ever more complex crude oils as the reserves of lighter oils are being depleted.

Barry's research on adsorption aims to understand the fundamental mechanisms by which activated carbon monoliths (ACMs) can be used to adsorb organic compounds from air streams.

ACMs are ideal in air pollution control applications since they offer high adsorptive performance, low pressure drop and the ability to be electrically heated. The monoliths can thereby offer one of the world’s fastest thermal swing processes.

In this context, Barry is co-inventor of an award-winning commercial clean technology process that is under development for the recovery of solvents in factory environments using ACMs. In both areas of research Barry collaborates with leading industrial companies, nationally and internationally.
