Capturing CO₂ with catch4climate

The pure oxyfuel process (from “oxy” for oxygen and “fuel” for fuel) is a clinker production process in which pure oxygen is introduced into the kiln instead of air to ensure heat generation during combustion without the presence of atmospheric nitrogen. In this way, the CO₂ concentration in the kiln exhaust gas is increased to approximately 90 per cent, thereby significantly enhancing the potential for CO₂ capture. The aim is to capture up to 100 per cent of a cement plant’s CO₂ emissions in a cost-efficient manner, enabling the subsequent utilisation or storage of the captured CO₂. By adopting this technology, the European cement industry could facilitate the utilisation or storage of its CO₂ emissions and thereby make a significant contribution to climate protection.
