Chemical and Process Engineering

The two areas of Explosions and Fire, and Green Process Engineering are at the centre of our research activity

Explosions and Fire research focuses on hydrogen safety - examining the likelihood of ignition of hydrogen-air mixtures (mechanical and electrostatic), characterisation of underwater hydrogen releases and mitigation of hydrogen gas explosions using water fog, nitrogen dilution and chemical additives. The results have been used to help Sellafield Ltd address knowledge gaps in their current hydrogen safety guidance and assist in the development of safety cases for nuclear decommissioning operations. Such research enables the development of strategies to prevent or mitigate hydrogen explosion accidents, helping to maintain the integrity of the nuclear waste plants and protect the environment from the threat of an uncontrolled radioactive release.

Green Process Engineering (GPE) is one of the active and emerging research areas at LSBU that looks at designing sustainable and safe chemical processes. It integrates new, environmentally-friendly chemical routes and technical innovation to achieve green chemical process development. The research covers greening of alkene/terpene epoxidation, graphene from supercritical fluid technologies, biodiesel production from used cooking oil (UCO), CO2 conversion to value added chemicals and fuels and continuous synthesis of value added products using multi-functional reactors such as FlowSyn continuous flow reactor, reactive distillation column (RDC) and chromatographic reactor. The research has been funded by the UK Engineering and Physical Sciences Research Council (EPSRC), The Royal Society and the industrial partners.
