Abstract:

This data set includes ejection rates of Corexit surfactants (DOSS and Span 80) and alkane aerosols measured in the reactor effluent of a bubble column during laboratory experiments.

Combined Experimental and Molecular Simulation Investigation of the Individual Effects of Corexit Surfactants on the Aerosolization of Oil Spill Matter. The Journal of Physical Chemistry A, 120(30), 6048–6058. doi:10.1021/acs.jpca.6b04988

Purpose:

This data set was developed to demonstrate the potential for Corexit surfactants (DOSS and Span 80) to be aerosolized under conditions simulating breaking waves. The potential for Corexit surfactants to increase the mass of semi and nonvolatile hydrocarbons was also evaluated. The ejection of alkanes and Corexit surfactants from crude-oil-surfactant mixtures were quantified. Additionally, classical molecular dynamics (MD) simulations were also undertaken to investigate the thermodynamic incentives leading to aerosolization. The results of the molecular simulations were compared to the experimental observations.

Data Parameters and Units:

Surfactant and alkane concentration (ug/L), ejection rates (ug/min), mass of reactor container (g), mass of reactor container + effluent (g), mass of effluent (g), collection time (min), density (g/ml)

Methods:

Limits of Detection = DOSS (200 ng/L), Span 80 (20000 ng/L),

Instruments:

Data presented was generated on an Agilent 1100 HPLC system interfaced with a Waters Aquity Triple Quadrupole mass spectrometer (surfactants) or an Agilent 6890 GC-MS system and Agilent 5890 II GC-FID (alkanes).
