ACACIA Project – Development of a Post-Combustion CO₂Capture Process. Case of the DMX^TMProcess

Abstract

The objective of the ACACIA project was to develop processes for post-combustion CO<sub>2<sub/> capture at a lower cost and with a higher energetic efficiency than first generation processes using amines such as MonoEthanolAmine (MEA) which are now considered for the first Carbon Capture and Storage (CCS) demonstrators. The partners involved in this project were: Rhodia (Solvay since then), <i>Arkema, Lafarge, GDF SUEZ, Veolia Environnement, IFP Energies nouvelles, IRCE Lyon, LMOPS, LTIM, LSA Armines<i/>. To validate the relevance of the breakthrough processes studied in this project, techno-economic evaluations were carried out with comparison to the reference process using a 30 wt% MEA solvent. These evaluation studies involved all the industrial partners of the project, each partner bringing specific cases of CO<sub>2<sub/> capture on their industrial facilities. From these studies, only the process using demixing solvent, DMX<sup>TM<sup/>, developed by IFPEN appears as an alternative solution to the MEA process.
