This paper presents an evaluation of the ability of a non-ionic surfactant solution (Triton X100) for removal of Flourene, Phenanthrene from soil artificially contaminated with crude oil supplied from Tehran refinery. PAHs fractions were gained in accord to MOOPAM standard and analyzed by GC-FID. The effects of mixing time, surfactant solution concentration and volume were evaluated at 4 levels. Results...
Oily sludge, produced mostly in petroleum refineries and petrochemical industries, is one of the major industrial wastes that require treatment. The objective of this work was to recovery oil by washing of oily sludge with nonionic and anionic surfactant. To compare experimental results, three surfactants were used: sodium dodecylbenzene sulfonate (DBS), alkyl phenol polyoxyethylene ether (OP-10)...
Oily sludge is a common by-product of petroleum processing, storage and transport. It is currently treated to a minor extent before it is disposed of in a landfill. However as energy casts rise, and environmental impacts become of greater concern, there is increased interest in developing a means to reduce the amount and toxicity of this waste, and to recover useful materials. In this paper, the oily...
