| Yhteenveto: | Among the potentially polluting economic activities that compromise the quality of soil and
groundwater stations are fuel dealers. Leakage of oil derived fuels in underground tanks or
activities improperly with these pollutants can contaminate large areas, causing serious
environmental and toxicological problems. The number of gas stations grew haphazardly,
without any kind of control, thus the environmental impacts generated by these enterprises
grew causing pollution of soil and groundwater. Surfactants using various techniques have
been proposed to remedy this kind of contamination. This study presents innovation as the
application of different systems containing surfactant in the vapor phase and compares their
diesel removal efficiencies of soil containing this contaminant. For this, a system that contains
seven injection wells the following vaporized solutions: water, surfactant solution,
microemulsion and nanoemulsion, The surfactants used were saponified coconut oil (OCS), in
aqueous solution and an ethoxylated alcohol UNTL-90: aqueous solution , and nanoemulsion
and microemulsion systems. Among the systems investigated, the nanoemulsion showed the
highest efficiency, achieving 88% removal of residual phase diesel, the most ecologically and
technically feasible by a system with lower content of active matter |
