Abstract The objective of this research project was to investigate theoretically the behaviour of spillages of sulfur trioxide (SO3) and oleum (mixture of SO3 and sulfuric acid H2SO4) and to develop a model describing the behaviour of the resulting cloud. The parameter principally governing the spill behaviour is the amount of water available for reaction. Cloud behaviour is mostly affected by wind speed, vapour evolution rates, atmospheric stability and atmospheric relative humidity.
