A new four-year project will demonstrate a newly developed process designed to capture carbon dioxide (CO2) from blast furnace gases, as well as other applications, to help reduce CO2 emissions in France.

The project titled Demonstration and Innovative Applications of the DMX™ Process, was launched earlier this week by IFPEN, Total Refining & Chemicals and ArcelorMittal France.

Developed by the French Institute of Petroleum (IFPEN), the DMX™ process uses a solvent for separating CO2 via adsorption with a high capture capacity.

Made up of a mixture of two amines in aqueous solution and initially forming a single phase, the so-called demixing solvent splits into two phases when in contact with flue gases laden with CO2.

Since the CO2 is concentrated in one of the two phases, it significantly reduces the volume to be treated during the energy-intensive phase.

The process will initially be demonstrated on the pilot unit built for the European H2020 3D project at ArcelorMittal’s site in Dunkirk.

In a statement, IFPEN said the technology should make it possible to reduce the cost of CO2 capture by 30% compared to more traditional processes.
