Technology of the Thermochemical Treatment of Oily Sludge ...

The ,thermochemical, mechanism ,of oily sludge, and the ,treatment, technology of incineration,low temperature pyrogenation,direct liquefaction,coking,melting were introduced in this paper.Also the principles of various techniques and their advantages and disadvantages were analyzed.Finally,some advices were given to ,oily sludge treatment, techniques in our country.

The method of extracting oil from oily sludge
The method of extracting oil from oily sludge

In ,oily sludge, (oil Sands, oil contaminated soil, heavy oil deposits in the systems of production, transportation, storage and refining of oil, for example, in pipelines, storage facilities and equipment refineries) is introduced as solvent a mixture of fractions of the distillation of petroleum with a boiling point 50-220 o C until reaching a constant density slurry solution.

Treatment of Daqing oily sludge by thermochemical cleaning ...
Treatment of Daqing oily sludge by thermochemical cleaning ...

The ,thermochemical, cleaning method was used to treat the ,oily sludge, produced from Daqing oilfield. Cleaning agents were screened innovatively by using interfacial tension (IFT) method. The mixture of sodium carbonate, fatty alcohol ethoxylate (AEO-9), and rhamnolipid with a ratio of 5:1:0.5 was found that had the lowest IFT.

Oil sludge washing with surfactants and co-solvents: oil ...
Oil sludge washing with surfactants and co-solvents: oil ...

Different physicochemical and biological treatments have been used to treat oil sludges, and oil recovery techniques are preferred such as oil ,sludge, washing (OSW) with surfactants and co-solvents. Toluene is commonly used as co-solvent, but it is non-benign to the environment. This study tested alternative co-solvents (n-pentane, n-hexane, cyclohexane, and isooctane) at 1:1 and 2:1 C/OS (co ...
