This paper presents the main results of Task 13.4 of the OCTAVIUS project dedicated to the benchmarking of DMX versus MEA 30 wt. % CO2 capture processes. In the introduction are given the main objectives of the FP7 Project OCTAVIUS, which ended in June 2016. In this first part are also presented the main characteristics of the DMX process developed by IFP Energies nouvelles (IFPEN) and licensed by PROSERNAT, which uses a phase change solvent. The benchmarking study takes into account the design and the optimal integration of the CO2 capture process within the power plant and the CO2 compression at 110 bara. The thermal integration has been realised by TUHH. The design and evaluation of the capture processes were carried out by IFPEN based on the results of mini-pilots experimentation within OCTAVIUS and of previous works. The comparison has been performed for a reference power plant (805 MWe coal power station) using criteria defined jointly with the industrial partners of the OCTAVIUS project. This techno-economic study confirms that the DMXTM process is very promising as it allows a reduction in energy penalty compared to the MEA reference process without Lean Vapour Compression by approximately 2% points. As a consequence, it gives lower Cost of Electricity and lower avoided CO2 cost: 42.6 €/tCO2 (56.5 €/tCO2 for the MEA reference process). The DMX process needs now to be demonstrated in an industrial scale pilot plant.
