DMX Carbon Capture Process At Dunkirk Steel Plant Exceeds Expectations, Axens Says

DMX Carbon Capture Process At Dunkirk Steel Plant Exceeds Expectations, Axens Says - Carbon Herald

The industrial pilot project focusing on capturing carbon dioxide (CO2) from blast furnace gases at ArcelorMittal’s steel plant in Dunkirk, northern France, has surpassed expectations, according to a statement by Axens, one of the partners in the initiative.

Launched in April 2023, the project has achieved remarkable CO2 capture rates exceeding 90%, while also maintaining CO2 purity levels of 99.5% or higher and demonstrating low energy consumption.

The project is based on the DMX process, patented by IFP Energies nouvelles (IFPEN) and marketed by Axens, which utilizes an innovative amine demixing solvent to capture CO2 from industrial flue gases.

Unlike typical amine scrubbing solutions, DMX boasts lower energy intensity, resulting in reduced operating costs and mitigating potential environmental impacts, especially when the energy source is renewable.

The DMX capture process is aimed at the decarbonization of various industrial activities such as steelworks, cement plants, glassware manufacturing, refining, chemicals, and petrochemicals.

Operating within the European Union’s H2020 ‘3D’ project and the DinamX project, which aims to showcase the applications of DMX technology, the pilot focused on capturing CO2 from blast furnace gases emitted during steel production at ArcelorMittal’s Dunkirk site.

Vania Santos-Moreau, the project manager for 3D and DinamX, highlighted the culmination of 15 years of development, emphasizing the collaborative effort between IFPEN, partners, and stakeholders.

Its exceptional energy efficiency and solvent stability position it as a leading solution for CO2 capture, aligning with France’s capture, utilization, and storage (CCUS) strategy and national decarbonization goals, according to Axens.

The success of the Dunkirk demonstration paves the way for the broader adoption of DMX technology, offering a competitive and effective solution for reducing industrial emissions and contributing to global efforts towards a more sustainable future.
