Evaporation characteristics of multi-component liquid

Experimental measurement of initial evaporation mass flows from gasoline spills and comparison with empirical models

“…There are some papers published to the investigation of gasoline spill evaporation. [15][16][17][18][19][20][21] The evaporation is empirically described there mainly by adaptation of a mass transfer coefficient. In contrast to substances such as water or pure short-chain alkanes, mixtures of substances such as gasoline show deviating evaporation behavior.…”

“…In contrast to substances such as water or pure short-chain alkanes, mixtures of substances such as gasoline show deviating evaporation behavior. During the evaporation process, the composition changes as the more volatile components dominate the initial phase of evaporation, 17 and as a result, the overall dynamics of the evaporation changes significantly in time. 15,16 It is therefore clearly pointed out in Reference 16 that evaporations from gasoline spills, and especially from crude oil spills follow another dynamic, as can be expected in accordance with boundary layer related empirical models (cf.…”

Effect of Diffusivity of Petroleum Products on Human Health in Contaminated Areas

“…The mass loss reached 86.36% after 300 days. Most oil and petroleum products evaporated at a logarithmic rate with respect to time [5][6][7]. Evaporation rate was conducted with/without wind [8].…”

Calculation of Essential Input Parameters for Estimating the Evaporation of Multicomponent Liquid Droplets

“…Most of the evaporation calculations assumed that the gas-phase composition over the liquid phase is determined by the liquid-vapor equilibrium (Starov and Sefiane, 2009;Brenn et al, 2007;Okamoto et al, 2010). Librovich et al (2007) has shown that evaporating systems quickly evolve to quasiequilibrium states.…”

“…Librovich et al (2007) has shown that evaporating systems quickly evolve to quasiequilibrium states. For the modelling of activity coefficients, the authors usually applied the semiempirical van Laar equation (Okamoto et al, 2010) or the Wilson equation (Marchese and Dryer, 1996) with adjustable system-specific parameters. A widely used method to estimate the nonideality of liquid mixtures is the UNIFAC (Fredenslund et al, 1975; group-contribution approach for activity coefficients (Zudkevitch et al, 1995;Hatzioannidis et al, 1998;Brenn et al, 2007;Teixeira et al, 2009).…”
