Technip and Siemens look to decarbonise olefin production

Technology uses a dynamic reactor system that replaces conventional furnaces with a combination of electric and hydrogen-fired gas turbines

French engineering firm Technip Energies and Germany’s Siemens Energy are working together on a new technology to decarbonise refinery processes. The firms say their rotating olefins cracker (ROC) technology will decarbonise the production process for olefins. Light olefins, especially ethylene and propylene, are widely manufactured by the steam cracking of hydrocarbons—also known as pyrolysis. They are then mainly used in plastics. The new technology uses a dynamic reactor system that replaces conventional furnaces with a combination of electric-powered motors and hydrogen-fired gas turbines. The firms say they have already proved the technology in laboratory conditions and expect the first
