Seeking synergies in separation processes

Chemical processing plants are complex networks of process units, where separation units are at the heart of these networks. My research on process integration within these plants, focusing on separation processes, aims to develop useful approaches for modelling, design and optimisation: these techniques search for – and exploit – synergies that enable the clean and efficient use of raw materials, energy and equipment.

A major focus is on crude oil distillation. Although the technology has changed little in over 80 years, systems approaches continue to help with exploring and exploiting interactions between the distillation units and heat recovery system. Increasingly versatile modelling approaches are now being applied alongside machine learning to go beyond process design and retrofit towards real-time optimisation.

My work is also focusing increasingly on development of integrated processes, especially those which combine separation technologies and/or reactions. Such novel processes could potentially lead to step changes in what is technically feasible and what is economically viable. This work applies materials science, nuclear science, molecular modelling and industry-specific knowledge, together with process modelling and analysis, in fields as diverse as air separation and extraction of specific compounds from spent nuclear fuel.

This lecture will celebrate my journey – and my companions along the way – of some 25 years of seeking synergies in separation processes.
