Prediction of the rate of oil removal from seawater by evaporation and dissolution

Gas chromatographic retention index as a basis for predicting evaporation rates of complex mixtures

“…Physical weathering processes, including evaporation, change pollutant distribution by transporting constituents away from the initial point of release [2]. Evaporation is the most prevalent contributor to losses of volatile petroleum constituents, often accounting for up to 75% of the mass loss, and is therefore a critical component to oil spill models [2][3][4][5][6][7][8][9][10][11]. The weathering processes continuously change the composition of the fuel, as well as altering physical properties such as viscosity and density, making comprehensive modeling very challenging [9,12,13].…”

Accidental Oil Spills Behavior and Control

“…In general oil emulsions are masses of oil (nonvolatile part) that contain water-as much as 30 to 80 percent. If the amount of water is Salt concentration, weight 0% Oil solubility, 10 7 C, mol/lit Figure 5 Measured and predicted oil solubilities in water (Riazi and Edalat 1996) less or higher than these values, the oil-water emulsions are not very stable. Oil containing heavier hydrocarbons, especially asphaltenic components (molecular weights greater than 1000), have a higher tendency to emulsify.…”

“…State-of-the-art models include some, but not all, of these processes at varying degrees of sophistication, but field or laboratory experiments designed to calibrate or test models usually focus on only one process. For example, Huang and Monastero (1982), Spaulding (1988), Stiver et al (1989), Villoria et al (1991), Riazi and Edalat (1996), Riazi andAlenzi (1999, 2002), Riazi andRoomi (2005, 2008) and ASCE (1996) review and propose some of these models.…”

A Numerical Simulation for the Prediction Movement of Gas Condensate From Spill Accidents in the Assalouyeh Marine Region, Persian Gulf, Iran

“…A semi-analytical model of the rate of oil spill disappearance from seawater for Kuwaiti crude and its products has been developed by Riazi & Edalat 6 . The model considers evaporation, dissolution and sedimentation of oil components.…”
