To decarbonize air transport, the use of a growing share of less carbon-rich SAF (Substitute Air Fuels) will be mandatory. One of the most studied processes is MTO (Methanol To Olefins) which consists in producing methanol from carbon capture and water electrolysis, then reacting it to produce olefins.
The simulations of this process carried out previously at LSET considered continuous operation of the installation (ProSim Plus models).


Scientific issue to be addressed
In the perspective of decarbonisation of e-kerosene, the use of ENR electricity seems essential, which implies the study of the process under dynamic regime.

Study techniques
The complete system (CO2 capture, high temperature electrolysis, methanol loop, MTO reaction and purifications) should be simulated in dynamic mode. The software considered is Dymola for the process part. It can then be adapted to be integrated into a larger system with PERSEE
Several modes of system constraints are possible (ENR profile, kerosene demand curve,...).


Expected results
The dynamic model should give:
Size and cost of equipment;
Size and position of optimal storage;
Energy requirements and system efficiency;
Cost of kerosene produced.
