The Plastics2Olefins project will realize this in a two-step approach: first by adapting and testing a scaled pilot plant at Repsol Technology Lab to optimize the components and process conditions and finally, a full-scale industrial demonstration plant at Repsol’s industrial site, which will be finally operated in a six-months validation campaign.

To optimize the carbon footprint of such a plant, the project will design and construct the plant that it can be fully electrified by renewably generated electricity. Also, the project will deliver a concept for renewable energy integration and with the use of batteries and an EMS (Energy Management System) 100% renewable energy supply will be ensured. Coupled with this, a digital twin of the pilot plant will be developed to model the process dynamics of the whole unit, thereby enabling a twin transition. The digital twin will simulate the operating conditions & enable process scaling rules for a different feedstock and/or olefins-rich syngas throughput, identify risks and mitigation measures, provide decision making support. With the involvement of end users of the products, plastics and char, as well as waste providers in the project, the full value chain and life cycle of plastics will be covered to prepare grounds for the broad application of the technology.
