Butterfly

The Butterfly project, represents an advancement in kiln technology enabling low-carbon lime production through a parallel flow regenerative oxyfuel kiln designed to capture and concentrate CO₂ directly at the kiln level, integrating carbon capture into the core process rather than treating emissions downstream.

The project started mid 22 and is ending June 26.

WHAT IS THE SPECIFICITY OF THIS PROJECT?

The Butterfly project is a collaboration between Carmeuse, CRM Group, the University of Liège, the University of Mons, CORETEC, and VOC Sens, and has received funding support from the Walloon region and the European Union.

The construction of the industrial demonstrator started in June 2023. During the last campaign (March-April 26), we achieved our target of reaching more than 80% CO2 in the flue gas, while confirming the good quality of the lime product. We also improved the reliability of the equipment and the instrumentation to properly measure CO2.
