ENGINEERS at Coolbrook and ABB have set their sights on replacing steam cracking technology with a novel turbomachine called the Roto Dynamic Reactor (RDR) that they will pilot at a chemicals site in the Netherlands later this year.

The idea is to use an electrically-driven turbomachine powered by renewable energy in place of the conventional fossil-fuelled steam cracking processes that industry uses to produce olefins such as ethylene and propylene from ethane or naphtha.

Coolbrook, which has developed its Roto Dynamic Reactor through collaborations with the universities of Oxford, Cambridge, Ghent, Neste Engineering and Mitsubishi Heavy Industries, says the technology can replace a conventional furnace by directly imparting the rotor shaft’s mechanical energy to the hydrocarbon fluid.

This is achieved by aerodynamic action through a rotating blade flow.

As well as eliminating CO2 emissions from the traditional steam cracking process, Coo
