Ultrasonic Demulsification Equipment

Crude oil water is a common phenomenon in oilfield development. The water-containing crude oil must be dehydrated and desalted before processing, in order to reduce the corrosiveness of the processing equipment and the formation of scale layer, reduce the harm of impurities in the crude oil to the catalyst of the subsequent processing, and effectively improve the product quality.

Ultrasonic demulsification equipment is a demulsification method that can effectively solve such problems. After ultrasonic treatment, the dehydration and desalination effect of crude oil is significantly improved.

Principle of ultrasonic demulsification equipment

Ultrasonic demulsification equipment is based on the "displacement effect" generated by ultrasonic waves acting on fluid media that are not used to achieve oil-water separation. Due to the "displacement effect", the water ions will continuously move, gather and collide in the direction of the antinode or the node, and generate water droplets with larger diameters and separate from the oil under the action of gravity. In the standing wave field, the uneven distribution of the sound pressure causes the water particles to be unevenly distributed, which is more conducive to the collision of water particles in the crude oil, thereby achieving the purpose of demulsification. The equipment mainly uses the mechanical vibration and heat of ultrasonic waves.

1. Mechanical vibration promotes the condensation of water particles. When the ultrasonic waves pass through a crude oil medium having suspended water particles, the suspended water particles are caused to vibrate together with the crude oil medium. Since the suspended water particles of different sizes have different relative vibration speeds, the water particles will collide and adhere to each other, so that the volume and mass of the particles are increased

2. The mechanical vibration can disperse the natural emulsifier such as paraffin, colloid and asphalt in the crude oil medium, increase its solubility, reduce the mechanical strength of the oil-water interface film, and facilitate the separation and separation of the water phase.

3. The heat action can reduce the strength of the oil-water interface film and the viscosity of the crude oil. On the one hand, the boundary friction increases the temperature at the oil water boundary, which is conducive to the rupture of the interface film. On the other hand, the absorption of part of the acoustic energy by the crude oil can reduce the viscosity of the crude oil and facilitate the gravity sedimentation separation of the water particles.

Ultrasonic demulsification equipment advantages

1. Ultrasound can reduce the temperature of crude oil dehydration compared with other demulsification methods, thus reducing energy consumption.

2, ultrasonic demulsification equipment can eliminate complex high-voltage electric dehydration equipment.

3, ultrasonic demulsification equipment can greatly reduce the amount of demulsifier.

4. After the ultrasonic treatment of the crude oil, the fluidity is greatly increased, and the viscosity of the crude oil is not restored for a long time.

5. After ultrasonic treatment, the crude oil standing time can be greatly shortened.

6, the use of ultrasonic demulsification equipment can effectively reduce production costs and improve economic efficiency.

The ultrasonic demulsification device consists of two parts: an ultrasonic demulsification system and an ultrasonic drive system (ultrasonic generator).

Ultrasonic demulsification equipment mainly includes an ultrasonic transducer, an ultrasonic horn, and an ultrasonic tool head for generating ultrasonic vibration, and the vibration energy is emitted into the liquid.

Ultrasonic transducer

Converting the input electrical energy into a mechanical energy representation is that the transducer moves back and forth in the longitudinal direction, typically at a few microns in amplitude.

Ultrasonic horn

Due to the insufficient amplitude generated by the ultrasonic transducer, it is necessary to connect the ultrasonic horn, and the amplitude is amplified according to the design, the reaction solution and the ultrasonic transducer are isolated, and the entire ultrasonic vibration device is also fixed.

Ultrasonic tool head

Connected to the horn, the horn transmits ultrasonic energy vibration to the tool head, and the ultrasonic energy is emitted from the tool head into the chemical reaction liquid.

Ultrasonic generator

Generate high frequency and high power current to drive the ultrasonic vibration component to work. The power of the ultrasonic generator is adjustable to suit different operating conditions. A timing controller can also be integrated in the generator to control the ultrasonic vibration time and intermittent time.
