A new robust regenerative turbo-reactor concept for clean hydrocarbon cracking

Energy consumption in the chemical and petrochemical industries is dominated by highly energy-intensive, high-temperature hydrocarbon cracking process. This paper offers an attractive solution to potentially decarbonise industry direct renewable electrification whilst also improving efficiency of energy transfer enhancing quality overall Controlled endothermic reactions are generated mechanical using a new electric-motor-driven turbo-reactor replace fossil-fuelled radiant unit conventional plant. study provides introduction novel concept, focusing on how unique three-blade-row repeating stage design exploited order drive efficient transformation processes used overcome fundamental limitations More specifically, this includes increasing primary product yield, mitigating coke deposition operability. A combination URANS high-fidelity LES presented probe aerothermal flow physics interactions rotor diffuser. clearly demonstrates working principals elemental can be realised uniformly across full regenerative exploiting robust naturally self-adjusting concept. work highlights high-level controllability turbomachine, which allows environment species selectivities tailored during operation, for example, conducting minor alterations rotational speed.
