Abstract


In this paper, tank bottom oily sludge from Liaohe oil field of China was treated by a new reagent and processing based on thermal chemical washing method. Several surfactants were investigated using oil removal efficiency of oil sludge including Sodium dodecyl benzene sulfonate, Sodium dodecylsulphate, and Dodecyl trimethyl ammonium bromides, Betaine, Tween 80 and Span 20. Processing conditions, including temperature, mass ratio of liquid to solid and stirring time, were also optimized.
