Description
Technical field
The present invention relates to crude oil preconditioning technique field, particularly relate to a kind of ultrasonic dehydration desalting and dewatering pipeline.
Background technology
For oil-processing enterprises, the salt in abjection crude oil is the main purpose of pretreatment, in order to reduces and produces
Power consumption, reduces equipment corrosion and fouling, it is to avoid catalyst poisoning.Along with oil field secondary, the enforcement of tertiary oil recovery technology and oil field
Being continuously increased of chemical dose, crude oil occur in that retrogradation, become weight, salt content raises and the trend such as emulsifying is more serious, adds electricity
The difficulty of desalination.Oil plant uses the integrated processes desalination of conventional heating-high voltage electric field-chemical demulsifier, electric current often occurs
Superelevation is reported to the police, it is impossible to the situation of normal water filling, causes electro-desalting effect poor, and chemical demulsifier is to different types of crude oil
Having bigger limitation, production operation is complicated, and cost is high.
In crude oil preprocessing process, ultrasonic dehydration technology mainly by ultrasound wave to the agglomeration effect of crude oil and fall
Viscous effect, makes water droplet gathering in crude oil become big, accelerates oil, water separation, be effectively improved crude oil demulsification effect, reach desalting and dewatering
Purpose, is that the crude oil entering distillation column conforms to quality requirements.
Traditional crude oil dewatering and desalting processes and all carries out in desalter, and so its construction cost increases, relatively in oil transportation
It is processed on pipeline, and directly carries out dewatering and desalting and process and both saved the cost built needed for pretreatment factory, again can
Decrease crude oil and enter the time required for refinery's refine, saved time cost, i.e. economy is the most practical.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of ultrasonic dehydration desalting and dewatering pipeline, it is possible at petroleum pipeline
On road, crude oil is carried out dewatering and desalting process, by crude oil and sloughed by several oil water separators arranged on oil pipeline
Salt ion moisture leaves, and is focused on, by a drainage pipeline, the salt ion water sloughed, and reaches the purpose of environmental protection.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of ultrasonic dehydration desalination
Dehydrated tube, it is characterised in that including: oil pipeline, oil water separator and drainage pipeline；
On described oil pipeline, each segment distance arranges a crude Treatment district；Described oil water separator is positioned at each crude oil
After treatment region；The discharge outlet of described oil water separator is linked together composition drainage pipeline by water pipe.
Preferably, described crude Treatment district includes on carried of crude oil direction, ultrasonic Treatment district, front end and rear end electro-desalting
Drying zone；Described crude Treatment district inboard wall of tube body is coated with strong floor, arranges ultrasonic transducer, prolong crude oil in described strong layer
Transporting direction, arranges loop type battery lead plate at ultrasonic transducer rear；The outer wall of crude Treatment district body is fixed with enhancement Layer；
Described strong layer inwall is coated with anticorrosive coat.
Preferably, described oil water separator uses compressed air oil water separator, is rushed crude oil by compressed air
Produce after hitting and flow to the drastically change of flow velocity, then rely on inertia by water and separating of oil to open, and by drain pipe, water is concentrated discharge.
Preferably, described strong layer uses polypropylene random copolymer material, and addition potassium dichromate is used for suppressing wherein
Corrosion sound.
Preferably, described anticorrosive coat uses Vinylidene Chloride coating.
It is different from the situation of prior art, the invention has the beneficial effects as follows: can effectively promote crude oil dewatering and desalting effect
Rate, uses multistage desalting and dewatering in oil pipeline, it is possible to reduce the use of chemical demulsifier before oil transportation so that petroleum pipeline
Road internal chemical fouling reduces, and prevents pipe interior from blocking.In body, ultrasonic transducer is arranged simultaneously, additionally it is possible to plays and prevents
The effect of pipeline obstruction, by machinery concussion and the cavitation of ultrasound wave, in making pipeline, electrode desalting efficiency is higher.
