During the exploration, extraction, refining, tank cleaning, and gathering and transportation of petroleum, a large amount of sludge is generated. Due to third-party factors, natural sedimentation, and other factors, crude oil may escape, drip, or leak. A large amount of crude oil or oil products, along with soil, water, and other impurities, form sludge containing crude oil or certain impurities in crude oil, which can cause serious damage and threats to the environment.
Oil sludge can be divided into brownish black ground oil sludge, tank bottom oil sludge containing heavy oil components such as sand, soil, heavy metal salts, paraffin, and asphalt deposited at the bottom of oil tanks, oily sludge produced by refineries, and ground oil spills.
The technology and equipment required for treating sludge are relatively high, which invisibly increases the difficulty and cost of sludge treatment. In addition, sludge has a huge impact on environmental pollution, so it is urgent to treat sludge. At present, there are various methods for treating oil sludge, among which oil sludge cracking is one of the more ideal methods for treatment results.
