Normative legislations relating to standards and international guidelines within the framework of carbon capture sequestration (CCS) and the transport of carbon dioxide in the actual operating conditions are still under development. The focus of the present study is the cold jet modelling, including the orientation factor, representing a scenario still partially unexplored. The framework provides by simple analytical formulae the boundaries of the jet region and air entrainment behaviour, as well as the resulting ground level hazardous concentrations to humans. The model relies on a first experimental validation of the jet phase, evidencing that the model can be applied, at least as a first cautious screening tool, for safety distance evaluation.

Abstract
Normative legislations relating to standards and international guidelines within the framework of carbon capture sequestration (CCS) and the transport of carbon dioxide in the actual operating conditions are still under development. The focus of the present study is the cold jet modelling, including the orientation factor, representing a scenario still partially unexplored. The framework provides by simple analytical formulae the boundaries of the jet region and air entrainment behaviour, as well as the resulting ground level hazardous concentrations to humans. The model relies on a first experimental validation of the jet phase, evidencing that the model can be applied, at least as a first cautious screening tool, for safety distance evaluation.
