Numerical Studies on CO2 Release and Dispersion Field Experiments

Carbon Capture and Storage (CCS) is one of the possible mitigation measures to reduce the CO2 emissions into the atmosphere and thus help addressing the issue of global warming. Accidental CO2 releases can occur at the capture site, during transportation through pipelines and during geological storage having harmful consequences on the people who work in CCS facilities, the general public in their vicinity and the environment. Numerical codes and models are increasingly used tools to investigate the behaviour of released substances and predict the consequences of hazardous scenarios. This information allows the development of measures to minimize the probability of an accident and also of the methods to mitigate the consequences in case of an accident. Validation of numerical codes and models is a crucial preliminary stage before the application of the models/codes to safety and risk assessment analysis. In this context, numerical simulations of CO2 release and dispersion field experiments are performed with a CFD code. The experimental data were taken from the Kit Fox CO2 gas field experiments which covered ground level short-duration transient and continuous releases. The Kit Fox experiments were designed to investigate the effect of ground roughness of industrial process plants and meteorological conditions on the formation and extent of the CO2 gas cloud. This study presents a systematic comparison between the simulation results and the experimental measurements in order to assess the accuracy of the numerical code and validate its performance for CO2 safety studies.
