HERAZO-NAVAJAS, Duvanis Enrique  e  ROMERO-HERNANDEZ, Antonio. Evaluation of a surfactant of natural origin as a dispersant in oil spills in seas. Dyna rev.fac.nac.minas [online]. 2021, vol.88, n.218, pp.230-238.  Epub 29-Mar-2022. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v88n218.93114.

Among the different agents for controlling oil spills in seas, natural dispersant formulations are presented as a sustainable alternative to conventional chemical dispersants. This study analyzes the efficiency of a surfactant mixture of vegetable origin with D-limonene solvent, to disperse petroleum hydrocarbons present in salt water bodies. This was evaluated with two types of commercial hydrocarbons in Colombia: Castilla Blend crude of 19.1 ° API and South Blend crude of 29.8 ° API. The data showed an average dispersion effectiveness of 22.83% for Castilla Blend and 49.98% for South Blend crude respectively. These results reveal the potential of natural surfactant mixtures to be an ecological and economical solution in the control of hydrocarbon spills.
