methanol from several sources can feed into a single Honeywell UOP eFining unit, or a customer can co-produce SAF and renewable methanol, or even renewable olefins. As the second step in the eFining process, Honeywell UOP’s olefins-to-jet fuel process is founded on significant experience with oligomerisation technologies. Overall, Honeywell UOP eFining can reduce greenhouse gas emissions by up to 88% compared to conventional jet fuel. This technology enables rapid access to SAF by converting e-methanol, produced from renewable energy sources, into jet fuel. The process is scalable, reliable, and offers high SAF yield and selectivity. The integrated solution with JM’s eMERALD technology provides efficient hydrogen feedstock usage for SAF production, unlocking additional annual revenues and lowering costs. Honeywell UOP are members of an ASTM task group actively pursuing qualification for MtJ as an approved pathway to SAF to fully meet the requirements for its use as an aviation fuel. Integrated and hub-and-spoke approaches Hub-and-spoke model The hub-and-spoke model is based on multiple small methanol plants providing methanol to one centralised MtJ facility. This enables methanol producers to have multiple potential off-takes for their product. It also allows MtJ producers to take advantage of economies of scale as they can source methanol from multiple locations. The hub-and-spoke model is ideal for methanol production locations with abundant
renewable electricity and carbon sources. MtJ facilities can be located close to high SAF demand centres such as Western Europe, leading to cheaper SAF production. Considerations regarding the shipping of methanol need to be made when using this strategy. Methanol is an easily transportable liquid at ambient temperatures and is a globally traded commodity. However, when sourcing methanol globally, it is important to consider the additional carbon intensity from shipping, as this will contribute to the overall SAF carbon intensity. Integrated approach JM’s eMERALD methanol process and Honeywell UOP’s eFining process can be integrated when located on the same site. This gives several benefits to the overall facility, including combined utility savings, hydrogen efficiency improvements, and interface optimisation. Hydrogen efficiency improvements can be achieved by recycling MTJ off-gases to the methanol synthesis plant. This process recovers hydrogen and increases methanol production by an additional 1.2%. Further optimisation of hydrogen recovery in methanol synthesis can enhance this process. These integrations mean that an integrated facility produces more SAF per tonne of hydrogen feedstock. This additional SAF production can be worth $8.3 million in additional annual revenues based on a 242 ktpa SAF plant. Secondly, integration reduces utility requirements for the overall facility by 30% through heat and carbon integration, which
