pressure, and the interaction between syngas and solvent chemical species. For this study, hot potassium carbonate carbon capture technology has been selected. Amalgamation of established technologies for novel process synthesis The Protos Biofuels process leverages experiences from proven technologies, such as RDF processing, gasification, syngas clean-up and compression, acid gas removal, conventional FT, and hydrotreating, to innovative applications such as waste syngas production, heavies, and tar reformulation to increase syngas yield, and one-step FT liquid fuels production with negligible wax. Also, the location of an RDF handling facility next to a flammable liquid fuels unit governs the equipment selection strategy within common design practice and applicable standards. Conclusion The Protos Biofuels process opens a viable pathway to SAF production using local resources and meets the UK Government target for SAF mandate. It converts RDF to syncrude that can be readily refined and co-processed to form SAF using conventional refining processes. The process is an amalgamation of proven technologies like gasification and GTL technologies applied to areas like waste syngas production and hybrid FT to produce liquid fuels. Additional research can be conducted to achieve greater efficiencies. In new, one-of-a- kind projects like these, technology assessment, energy integration, scale-up, and process intensification studies are critical in addressing the challenges that arise with such endeavours. The methodology used to carry out this project included all these steps, which not only add value to the project but will also be critical to the pathway’s overall success.
