| Abstract: | Fuming sulfuric acid (oleum) is one of several hazardous chemicals routinely transported in bulk quantities on US waterways. In the event of a marine accident, a large amount of the cargo acid could suddenly be released into water, resulting in the formation of a dense sulfuric acid cloud. Experiments were carried out in the laboratory to study the factors controlling the extent of acid aerosol formation under conditions likely to occur in maritime spill accidents. A Sinclair-type diffusion battery was used for aerosol sizing. In this presentation, a brief discussion of an improved nonlinear iterative inversion method for the analysis of diffusion battery data is given. Experimental results obtained with monodisperse test aerosols and sulfuric acid aerosols formed during oleum spills are presented. It is shown that the diffusion battery, coupled with the inversion technique, is capable of sizing particles up to 0.8 ..mu..m in diameter. |
