There is a risk of hazardous releases of CO 2 from Carbon Capture and Storage (CCS) facilities and infrastructure. To predict the exposure to the environment and to perform safety assessments, reliable and efficient simulation technology for detailed prediction of CO 2 dispersion in realistic, complex environments is needed. Here the development of an advanced industrial CO 2 dispersion simulation tool based on the CFD simulator KAMELEON FIREEX KFX ® is discussed. The tool's capability of predicting CO 2 dispersion at realistic conditions has been demonstrated through relevant tests and comparisons of simulation results to experimental data from both laboratory tests and large-scale field trials.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractWater is an efficient and environmental friendly means to mitigate and extinguish fires. However, it is not easy to judge the efficiency of water based mitigation and extinction systems due to complexity of the physics and geometry. Therefore advanced computation systems, like Kameleon FireEx KFX ® , must be utilized for a prediction of the interaction between the fire, its environments and the water droplets.
