Sebastião, P. e Guedes Soares, C. (1998), “Weathering of Oil Spills Accounting for Oil Components”, Oil and Hydrocarbon Spills, Modelling, Analysis and Control, R. Garcia-Martinez and C. A. Brebbia (Eds.), Computational Mechanics Publications, pp. 63-72.

A model is proposed to describe the weathering of oil spills taking into account the spreading, evaporation, emulsification, viscosity and density increase of the oil. The crude is described by a set of eight fractions, including paraffin, cycloparaffin, aromatic, naphtenoaromatic fractions and a high density residual. The evaporation process is computed for each fraction separately using a "pseudo-component" approach. This model is compared with another one, developed in a previous work, which treats the oil as a whole and uses evaporative exposure approach to models with experimental data available in the literature shows a significant improvment when the pseudo-component approach is used, with respect to the evaporation process.
