Qualitative and Quantitative Forecasting of Processes Affecting the Surface of Oil and Gas Condensate Slicks from Accidental Spill in the North Coast of the Persian Gulf

This paper presents governing equations of the processes affecting oil and gas condensate slicks involving spreading، evaporation، dissolution، and vertical dispersion، which are important for numerical models of oil spill. These equations are used for crude oil، light oil، and gas condensate spill accidents according to their physical and chemical conditions and atmospheric conditions of the sea between Khark Island and Busher port and Assalouyeh marine region in the winter and summer. The evaporation of gas condensate is 42. 17% at a temperature of 24. 9 °C in the winter while it is 62. 24% at a temperature of 38. 4 °C in the summer after 48 hours. Moreover، the dissolution of gas condensate is 0. 0385% after 48 hours in the summer. The results also show that the evaporation of oil is 39. 74% at a temperature of 20 °C in the winter while it is 62. 025% at a temperature of 35. 5 °C after 48 hours in the summer. Additionally، the dissolution of oil is 0. 0537% after 120 hours in the summer. The results were compared with results of other studies which show good agreement.
