A collaborative project involving Technip Energies and Siemens Energy is developing and commercializing rotating olefins cracker (ROC) technology to decarbonize olefin production processes. The 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.

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. Once fully commercialized, the process is also expected to have better first pass olefins yields with similar operating costs compared to the currently commercially available technologies.

The companies have already validated the fundamentals of the reactor technology in laboratory testing and intend for the first turbomachinery prototype to enter shop testing in the first half of 2022. Siemens Energy is contributing expertise in turbomachinery while Technip Energies brings 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, which include Borealis (member of the OMV Group), BP, Repsol, TotalEnergies SE, Versalis (Eni) and coordinator Brightlands Chemelot Campus.
