Germany: Decarbonization Rotating Olefins Cracker Technology to Advance Energy Transition of Olefin Production

Editor: Alexander Stark

Technip Energies and Siemens Energy announced an exclusive agreement to jointly develop, commercialize, and license the Rotating Olefins Cracker technology to decarbonize olefin production processes. The ROC technology employs a dynamic reactor system that replaces conventional furnaces used for pyrolysis when manufacturing light olefins — the building blocks for chemical products used in everyday materials, from packaging to polymers.

Berlin/Germany — Having already validated the fundamentals of the Rotating Olefins Cracker (ROC) technology in laboratory testing, Technip Energies and Siemens Energy intend for the first turbomachinery prototype to enter shop testing in the first half of 2022. The ROC technology offers driver flexibility, and when driven by electric-powered motors or hydrogen-fired gas turbines, the technology leads the path to decarbonize the process used to produce light olefins. The decarbonization impact is even more significant when the electric power or hydrogen fuel is derived from renewable sources. The ROC process, once fully commercialized, is also expected to have better first pass olefins yields with similar operating costs compared to the currently commercially available technologies.

Both companies bring specialized experience to commercializing this technology: Siemens Energy contributes its expertise in turbomachinery, while Technip Energies has extensive knowledge in pyrolysis cracking to produce light olefins and process integration.

As a milestone in the commercialization of this groundbreaking technology, Technip Energies and Siemens Energy entered into a Memorandum of Understanding (MOU) with the Cracker of the Future Consortium (COF). The MOU expresses the intent of the parties to negotiate a contract to install a hydrocarbon demonstration unit utilizing the ROC technology in a plant operated by one of the COF members.

The COF comprises major industry players Borealis (member of the OMV Group), BP, Repsol, TotalEnergies SE, Versalis (Eni), and coordinator Brightlands Chemelot Campus. The COF selected the ROC technology after assessing many electricity-based heating technologies for olefin crackers.
