Flush and capture free phase NAPL with Surfactant Applications.
Surfactant applications are utilized to break down the interfacial tension between fuel/oil and soil particles. This creates an emulsion which allows for more effective oxidant treatment of non-aqueous phase liquids (NAPL) zones or “hot” pockets.
Surfactants are used to flush and capture NAPL followed by an oxidant or bio-stimulant injection. Once injected, surfactant mixtures are generally allowed a brief residence time in the subsurface. Then the mixture is removed using a wide variety of methods.
The following is an example of the process.
Free phase NAPL clinging to saturated soil particles.
Injection of bio-surfactant (shown in green) as NAPL is desorbed and extracted.
After NAPL droplets are removed, the dissolved phase can be treated with ISCO or bio-stimulants.
