“…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.…”

“…Also, vertical diffusion during the evaporation process and concentration profiles was considered more closely. 20 In the cited literature, however, small spills on a floor or small liquid surfaces on Petri dishes or in round bottom flasks were considered. However, no equations are given which allow the estimate of In the present paper, the evaporation mass flow in the initial phase after the formation of the spills are to be estimated, not the precise influence of composition changes.…”

In this paper, we investigate the evaporation mass flow originating from spills of gasoline. Large spills of gasoline may form during partial or complete roof sinkings or in the case of perforations at various deck fittings at external floating roof tanks used for the storage. Additionally, spills may form in the retention area in the case of leakages at pipes or at the hull. The aim is to predict the order of magnitude of real-scale

“…For example, pure compounds evaporate in a linear manner, whereas most compounds in a multi-component crude oil mixture evaporate in a logarithmic manner (Okamoto et al, 2012). In this paper, we started our study with a pure compound -n-pentane, so that evaporation behavior might be different from a complex crude oil matrix.…”

Due to their mobility and toxicity, crude oil volatile organic compounds (VOCs) are representative components for oil pipeline contaminated sites detection. Therefore, contaminated location risk assessment, with airborne light detection and ranging (LIDAR) survey, in particular, requires ground-based determinative methods for oil VOCs, the interaction between oil VOCs and soil, and information on how they diffuse from underground into atmosphere. First, we developed a method for determination of crude oil VOC binary mixtures (take n-pentane and n-hexane as examples), taking synergistic effects of VOC mixtures on polydimethylsiloxane (PDMS) solid-phase microextraction (SPME) fibers into consideration. Using this method, we further aim to extract VOCs from small volumes, for example, from soil pores, using a custom-made sampling device for nondestructive SPME fiber intrusion, and to study VOC transport through heterogeneous porous media. Second, specific surface Brunauer-Emmett-Teller (BET) analysis was conducted and used for estimation of VOC isotherm parameters in soil. Finally, two models were fitted for VOC emission prediction, and the results were compared to the experimental emission results. It was found that free diffusion mode worked well, and an empirical correction factor seems to be needed for the other model to adapt to our condition for single and binary systems.
