Decontamination of oil facilities– Las Palmas      

 

Framework

-Storage facilities of oil products in harbor area.

-Very heterogeneous volcanic substrate, water table with marine intrusion and tidal influence.

Parameters to be treated

 

-2 sources in unsaturated zone (UZ), moderately light and heavy hydrocarbons C12-C35.

-Plume of Light Non-Aqueous Phase Liquid (LNAPL) by a mixture of hydrocarbons and dissolved phase in aquifer (2.800 m2)

Treatment

-Soil washing in UZ in source area by infiltration of surfactants and biostimulants.

-Explosive atmosphere (EXAT) of DPE high vacuum.

-Filtration of gases by activated carbon, decantation-separation of the liquid phase.

-Bioestimulation in the UZ of the source area.

Results obtained

-Recuperación de 0.6 m3 de fase libre y tratamiento de 500 m3 de aguas impactadas

Duration

-1.5 years: October 2014 – Present
