Abstract
A method for treating dirty oil of an oil refinery relates to a method for dehydrating hydrocarbon oil by an electrical or magnetic method. The method for treating the dirty oil of the oil refinery comprises the steps of heating a dirty oil thermostatic waterbath to a free flow state, adding a demulsifying agent, stirring uniformly, conducting ultrasonic treatment, and then settling in the thermostatic waterbath. The method has a very obvious dirty oil dehydration effect, and the dirty oil dehydration amount can be increased by about 2 times as compared with that of simple thermal settlement under equal conditions.
Description
Technical field
The present invention relates to a kind of by electric or magnetic means with the method for hydrocarbon ils dehydration.
Background technology
In general, the sump oil that refinery reclaims is the mixture of various oil products in the sewage, and character is complicated, and water content is high after the dehydration, and usually greater than 10%, moisture sump oil has the colloid of containing, bituminous matter is high, emulsifying capacity is strong, and foreign matter content is high, the more serious characteristics of degree of aging.Impurity in the sump oil is from drilling mud, down-hole acidifying, fracturing liquid, crude oil demulsifier and sewage-treating agent (flocculation agent, coagulating agent, Scale inhibitors, inhibiter, sterilant, caustic soda etc.).Because the sump oil complicated component contains more ionogen, good stability adopts the method for the sedimentation roughing out of heating to process usually, and the sump oil water content is namely sold less than 10% after processing, and has reduced the economic benefit of refinery.Utilize at present the ultrasonication sump oil, reduce this technology of sump oil water content and be subject to increasing attention.Ultrasonic wave oil-water emulsion demulsification and dehydration device and the technique of U.S. Teksonix company have obtained good effect.Many experimental study proofs make the emulsion dehydration have the superiority that ordinary method can not be compared with ultrasonic wave.
Summary of the invention
The present invention aims to provide a kind of method of processing the refinery sump oil, and it can obviously improve the dehydrating amount of sump oil.
A kind of method of processing the refinery sump oil of the present invention comprises: the sump oil water bath with thermostatic control is heated to easy flow state, then adds emulsion splitter, stir, and ultrasonication, then sedimentation in water bath with thermostatic control gets final product.
Preferably, hyperacoustic sound intensity is 1.168-1.250W/cm
2
More preferably, hyperacoustic sound intensity is 1.168W/cm
2
Perhaps further preferably, hyperacoustic frequency is 40KHz.
Perhaps further preferably, the time of ultrasonication is 10-15 minute.
Perhaps further preferably, emulsion splitter is the NS-2003 emulsion splitter, and consumption is 375 μ g/g.
Perhaps further preferably, the temperature during sedimentation is 60-70 ℃ in the water bath with thermostatic control.
Perhaps further preferably, the time of sedimentation is 2-4 hour in the water bath with thermostatic control.
The present invention is quite obvious to the dirty oil dewatering effect, and under equal conditions, its dirty oil dewatering amount is compared with simple heat sink falling, and can improve about 2 times.
Embodiment
Embodiment one.

2, frequency is ultrasonication 10-15 minute of 40KHz, then sedimentation 2 hours in 60-70 ℃ of water bath with thermostatic control gets final product.After testing, sump oil water content is 0.15%.
Embodiment two.
The sump oil water bath with thermostatic control being heated to easy flow state, then adding 375 μ g/g NS-2003 emulsion splitters, stir, is 1.250W/cm at the sound intensity
2, frequency is the ultrasonication 12 minutes of 40KHz, then sedimentation 4 hours in 60 ℃ of waters bath with thermostatic control gets final product.After testing, sump oil water content is 0.12%.
The comparative example.
The sump oil water bath with thermostatic control is heated to easy flow state, then adds 375 μ g/g NS-2003 emulsion splitters, stir, sedimentation is 4 hours in 70 ℃ of waters bath with thermostatic control, gets final product.After testing, sump oil water content is 0.35%.
