Background

A large amount of wastes (aging oil, oil sludge sand and tank bottom sediment) generated in the exploration, exploitation and gathering processes of the petroleum industry have high oil content and cannot be directly utilized, and crude oil cannot be recovered to cause a large amount of resource waste; the air-dried material is directly stacked and air-dried or buried underground, which causes serious pollution to the environment; at present, the oil-containing sludge is classified as dangerous solid waste (HW 08) by the country and is strictly controlled. The traditional process method has the characteristics that the components of the aging oil and the oil sludge sand are complex and difficult to treat, the recovery rate of the treated crude oil is low or the crude oil cannot be recovered, and the like, and aiming at the difficult-to-treat materials, the conventional homogenizing-dosing-heating treatment process is difficult to achieve the purposes of purification and recycling, reduction and harmless treatment of the crude oil. To this end, researchers have proposed new treatments, such as patent publications: CN102815806A discloses a dehydration treatment method for aging oil, which comprises the steps of adding a stripping agent into the aging oil, performing emulsion breaking and performing oil-water separation treatment; patent publication No.: CN 204342740U discloses a treatment method of an aging oil recovery system, which comprises the following steps: adding medicine into aging oil to be treated and heating; filtering the homogenized material, separating sewage, silt and recovered oil in two centrifugal separators, and then entering a settling tank for subsequent oil-water separation in two centrifugal separators, wherein the water content is higher by about 3 percent through separation treatment; patent publication No.: CN208471996U discloses an aging oil dehydration treatment device, and the method comprises the following steps: heating the aging oil to above 80 ℃, breaking the wall by using ultrasonic waves to break the emulsion to break the stable structure of water-in-oil, and then, centrifugally separating the oil, water and solid substances in a centrifuge, wherein the water content of the oil product treated by the method is higher by about 5 percent, and the ash content is higher; patent publication No.: CN104445848B discloses a method and a device for treating aging oil and oily sediment; firstly adding clean water, heating to 40-80 ℃, pressurizing by steam, introducing ultrasonic waves of 15-50Hz after heating, adding aging oil or oil sludge sand into a tank for three-phase separation of oil, water and solid, and the patent publication number is as follows: CN102241998A discloses an oil sludge sand processing apparatus and technology, includes: the device comprises a heat carrier, a rotary kiln, an oil gas condensation recovery device and a pyrolysis treatment system; patent publication No.: CN204824551U discloses an oil field oil sludge sand three-phase separation system, which is characterized in that agents such as ferrous sulfate, polyaluminium chloride and the like are added by stirring, and then the mixture enters a three-phase centrifuge to separate oil, water and solids. However, these methods also have difficulty in meeting practical production requirements.

The method which is widely applied and has obvious treatment effect is an improvement of treatment process method and has high effect on reduction treatment. Although some process technologies are matched with medicaments to treat aging oil or oil sludge sand, oil-water-solid is effectively separated, and water in crude oil and oil in sludge sand are removed, the problems and side effects of low recovery rate, poor separation effect, high energy consumption, incapability of continuous production and the like are also generated, such as the problems that the treated oil product has high water content and the part of the oil product with high ash content which is difficult to recover in the water phase and the solid phase in the pretreatment process of the aging oil is discharged into a sewage system such as a combination station and the like to impact other production and the like caused by poor medicament selection in the pretreatment process; although the crude oil in the silt can be reduced to 0.3 percent by thermal cracking, the energy consumption is high, the resource waste caused by the unrecoverable crude oil is caused, the potential safety hazard is caused by high-temperature coking decomposition in the pyrolysis furnace, and the tail gas generated in the pyrolysis process and the products after the pyrolysis have no clear identification standard. The extraction method for treating aging and oil sludge sand has high requirements on materials, high difficulty in recovering an extracting agent and strong operability in a laboratory, and is not popularized in the current practical production.
