The basis for the modelling and simulation of the industrial processes, the baseline of the project by means of the characterization of the current situation of the RETROFEED demo-cases and the analysis of the market and the feedstock variability has been set. At the same time, a preliminary methodology to guide the retrofitting actions has been presented, all in PR1.
Flame monitoring developed by CIRCE to SECIL has been finished and the two developments for clinker monitoring system have been installed by AIMEN in SECIL successfully. Finally, monitoring infrastructure and the control strategy has been defined. Additionally, DSS for each demo case has been tested and validated except for FTIB.
For the demo sites, the following developments have been carried out:
1)TCID: digital twin and DSS tested and validated. Engineering and installation for the retrofitted heat recuperator. Validation by melting 9 different frits in the retrofitted furnace. Improved high temperature recuperator. Feedstocks optimized in the production optimizing process draining smelter. Experimental campaign carried out.
2)SECIL: digital twin and DSS tested. Satellite burners has been installed and tested, allowing to use higher rates of RDF. Almost all sensors have been installed. Experimental campaign carried out.
3)ASAS: digital twin and DSS tested and validated. Design and construction of the oxygen lance, O2 level measurement system and delacquering system by STEK. Detailed engineering and design of control system. Commissioning and installation of all equipments and experimental campaign carried out.
4)FENO and SILCOTUB: digital twin and DSS tested. Design and construction of the innovative burner by HTT and CFD simulations by CSM. Commissioning of installation and experimental campaign carried out. Feasibility study of waste heat utilization done
6)FERTIBERIA: digital twin and DSS tested. Tests in pilot plant. Detailed engineering of the novel reactor. Preparation for commissioning.
Additionally, the correct performance of the RETROFEED solutions in each of the demo sites have been fine tunned. Its replicability potential has been analysed and their overall impact and improvements achieved. As well, the lessons learnt from the project in a methodology to support REIIs to undertake their retrofitting actions has been carried out.
Besides, within business plan and exploitation, final exploitation plan, final business plan, business models and bankability opportunities has been provided. Also, the standardization analysis and the environmental framework have been developed.
Finally, a successful social media campaign, several event organisations, the participation in national and international conferences and the organization of the final event have been carried out. Besides, development of training modules and e-learning platform have been finished.
