Design of an optimal intensified configuration coupling reaction, heat transfer and membrane separation for the direct synthesis of DME from CO2 and renewable H2
Résumé
The challenges of sustainability require to reduce the use of fossil fuels as raw materials and sources of energy,
and require the development of techniques allowing the conversion of CO2 to high added value products. The
process intensification has led to the design of innovative configurations and to the development of
multifunctional reactors. The integration of multiple functions within a process of DME direct synthesis is studied
and the impact of coupled phenomena (reaction, heat exchange and separation) on the reactor performances
of the DME direct synthesis is quantified. The effect of the parameters influencing the membrane reactor
performance is analysed and presented in this work. The simulation results show that the conventional reactor
performance can be improved by the proper coupling of equipment
