Abstract
A microwave-enhanced static crude oil dehydration device is mainly composed of a metal pipe section with a flange, and an electro-desalting / dehydration tank. Electrodes, insulating pieces and a microwave source are arranged in the metal pipe section with the flange. The electrodes and the pipe wall are connected and fixed through insulating materials. The adjacent electrodes are connected and fixed through insulating materials. The pipe section is grounded. The electrodes are connected with a transformer through electrode bars. The microwave source is perpendicular to the pipe section or installed with a certain angle between the microwave source and the pipe section. The rear portion of the pipe section is connected with the electro-desalting / dehydration tank. Microwave radiation is added when the electrostatic field effect of the microwave-enhanced static crude oil dehydration device is achieved, the demulsification effect can be enhanced, the microwave-enhanced static crude oil dehydration device is mainly used for demulsification and dehydration of crude oil and refined oil, the current of the electro-desalting / dehydration tank and the transformer is reduced, and therefore the energy consumption is lowered, and the adaptability and stability of the device are improved. The microwave-enhanced static crude oil dehydration device can be used for improving the separation efficiency in front of an oil field three-phase separator, and can be used for various two-phase separation places as well.
Description
technical field [0001] The invention relates to a microwave-enhanced electrostatic crude oil dehydration device, in particular to a device for desalting and dehydrating crude oil. Background technique [0002] As the oilfield development enters the late stage, the continuous development of the production technology, such as the application of technologies such as tertiary oil recovery water injection, polymer injection, ASP flooding, planing, and plugging removal, has added a large amount of chemical liquid to emulsify the crude oil produced in the oilfield The degree is getting worse, the crude oil emulsion becomes more stable, the conductivity of the emulsion is enhanced, and when a high-voltage electric field is applied, the current will increase, or even short circuit, and the dehydration becomes more and more difficult. The conventional electrochemical second-stage dehydration is already difficult. Meet the requirements of crude oil export indicators. [0003] With the...
