This depends on how the oil sludge is generated, if there is no contact with hazardous waste is not a hazardous waste.
Past treatment of oil sludge is mainly landfill method, in addition to landfill, there are other such as injection stratum treatment technology, curing treatment technology, curing treatment technology, etc., the new oil sludge cracking and recycling technology also has good results.
Thermal cracking treatment technology of oil sludge oil sands can be oil sludge oil sands for oil refining, thermal cracking treatment technology is oil field oil sludge in the anoxic conditions heated to the hydrocarbon cracking temperature, and then the hydrocarbons and water are recovered by condensation.
Oil sludge formation
Oil oxidizes under the catalytic effect of high-temperature environment, air, fuel vapors, and metals, and will form varnish and carbon, which are the beginnings of oil sludge, which is an unavoidable and normal phenomenon.
If the detergent and dispersant in the oil is not enough, or not at all, with the engine constantly working in high and low temperature cycles, coupled with the mixing of water vapor and gasoline vapor catalytic, leading to the accumulation of sludge, over time, the sludge adhering to the surface of the metal is more and more.
