Abstract(s) :

(Anglais) Nowadays, power generation and carbon-intensive industries (cement plants, steel plants…) are responsible for around 50% of anthropogenic CO2 emissions to the atmosphere that mainly contributes to global warming. Since two decades, CO2 capture techniques were investigated to envisage CO2 storage and chemical reuse. Beside the mature absorption-regeneration technologies using amine solvents but having an impact on the environment, Adsorption processes are a promising capture technique thanks to improvement of process design and development of new materials. Among these materials, MOFs appears as very promising materials for both gas separation and purification. However, the performances of these hybrid materials in carbon capture technologies have not been fully evaluated and fine-tuning is still needed for adsorption processes at large scale in real industrial conditions. The adsorption performances of MIL-160(Al) at a 200g-scale have been evaluated by pure component adsorption isotherms and breakthrough curves measurements. From these data, a complete simulation of Vacuum Pressure Swing Adsorption (VPSA) process was performed on Aspen Adsorption® software to evaluate the performances of different VPSA process configuration with MIL-160(Al). A 2-stage VPSA process with 2 beds and 5 steps and a 1-stage VPSA process with 3 beds with 5 or 6 steps have been investigated to reach the target of such a process: CO2 purity of 95% and recovery of 90%. A design of experiments (step times, flowrates, pressures) was carried out (i) to study the impact of these operating parameters on capture performance, (ii) to identify the adequate design to build a lab pilot capable of processing 1 Nm³/h of an N2(85%)/CO2(15%) mixture and (iii) to optimise the operating conditions.
