摘要: A water/surfactant process for removing oil from a soil that has been contaminated by an spill. The surfactant is carefully selected group consisting of linear alcohols having eight to fifteen carbon atoms and two ethylene oxide units on the atoms. concentration also held about 0.5 percent, volume, or less minimize formation emulsion between wash water. provides clean separation as well limited minimizes dispersion clay fines into heated improved removal soil.
