Problems solved by technology

Because the emulsion structure and chemical composition of these resource-utilizing crude oils are relatively complex, the traditional "electric desorption" technology can hardly meet the requirements of oil-water separation standards, and individual crude oils with special physical properties may even cause serious damage to existing "electric field facilities".
At present, the application of "crude oil ultrasonic demulsification and dehydration device and its demulsification and dehydration method" in oil-water separation in crude oil extraction and refining industry has not been found, so as to overcome the above disadvantages

Embodiment Construction

[0168] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0169] The crude oil ultrasonic emulsion dehydration device and the demulsification dehydration method thereof of the present invention respond to the characteristics of the ultrasonic wave, and with the help of the chemical activity of the chemical demulsifier, cooperate cooperatively to destroy the stable structure of the crude oil emulsion, and promote the rapid structural change of the crude oil emulsion. Realize efficient oil and water separation of crude oil.

[0170] figure 1 The present invention is a schematic block diagram of the overall structure of the ultrasonic generator; it is composed of a human-computer interactive digital display, an AVR high-speed embedded single-chip microcomputer, a digital synthesis module, a signal drive module, a power amplification module, a matching network module, and a generator housing. And other ...

Abstract

The invention relates to an oil-water separating technology in petroleum crude oil extracting and refining industry, in particular to a crude oil ultrasonic emulsion breaking dehydrating device and emulsion breaking dehydrating method thereof. The invention, combining with the characteristic of ultrasonic wave and chemical activity effect of chemical demulsifier, breaks the stable structure of crude oil emulsion, causes the crude oil emulsion to be rapidly changed in structure and realizes less consumed electric quantity, low demulsifier usage amount, through oil water separation and separation on crude oil with extremely low content in water and sedimented muddy sand. The invention is mainly applicable to china oil stations and oil extracting centralized field in oil field; and the invention can be applied if the oil field can normally extract oil and requires crude oil emulsion breaking dehydrating treatment.

Description

technical field [0001] The invention relates to an oil-water separation technology in petroleum crude oil extraction and refining industry, more specifically, it relates to an ultrasonic demulsification and dehydration device for crude oil and a demulsification and dehydration method thereof. Background technique [0002] The crude oil extracted from the oil layer is an emulsion, which contains a considerable amount of water and salt in addition to impurities such as mud and sand. NaCl and MgCl contained in crude oil 2 、CaCI 2 Except for a small part of inorganic salts suspended in crude oil in a crystalline state, most of them are dissolved in water particles in crude oil and form a relatively stable water-in-oil (W / O) emulsion. If the silt and salt-containing dissolved water contained in crude oil cannot be separated and removed, it will not only increase the transportation cost between oil production and refining, increase the dehydration and desalination burden of the ...
