High-frequency crude oil dehydrator

Abstract

The invention discloses a high-frequency crude oil dehydrator. A high-frequency dehydrator is connected with an impedance allocating network; a high-frequency radiator is connected with a temperature detection system; the temperature detection system is respectively connected with the impedance allocating network, a power amplification tank circuit, a high-frequency oscillation circuit and a detection and alarm system; the detection and alarm system is connected with a control system of a power supply system; the control system of the power supply system, the high-frequency oscillation circuit, the power amplification tank circuit and the impedance allocating network are all connected with a cooling system; a radial high-frequency electric field is generated by the high-frequency dehydrator at the high frequency; the orientation polarization is generated under the action of the electric field; two ends of water droplets induce and generate opposite charges to form an induction electric field; dipole coalescence is generated between the similar water droplets; the water droplets are condensed to form large water droplets; the large water droplets are demulsified and settled; the high-frequency electric field accelerates polar molecules to rotate at high speed and cause charge neutralization; when liquid globules lose the action of double electric layers, the liquid globules collide and gather, so that the oil and the water are separated. The high-frequency crude oil dehydrator has the characteristics of low operation cost, dehydration simplicity, high dehydration efficiency, stability and safety in dehydration, and green and environment-friendly performance.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and in particular relates to a high-frequency crude oil dehydrator. Background technique [0002] Heavy oil is an important part of the global petroleum hydrocarbon energy and has a very huge production potential. According to statistics, among the controlled and proven reserves of heavy oil in my country, ordinary heavy oil accounts for about 40%. Extra-heavy oil accounts for 12%, and super-heavy oil accounts for 48%. With the rapid development in recent years, the proportion of heavy oil in our crude oil production is also increasing. However, due to the high viscosity, high density, high colloidal asphaltene content, low oil-gas ratio, and large sand-carrying capacity of heavy oil, it is much more difficult to exploit, gather, transport, and process than conventional crude oil. Compared with colloids, the interfacial films formed by them are so strong that the demulsification and...

Problems solved by technology

The effect of microwave dehydration is good, but the frequency of high-power microwave is fixed, and it cannot be converted with the change of crude oil quality to achieve the best and most efficient dehydration. Moreover, the output power of microwave single tube is small, and the cost is high. The initial investment is large and the maintenance cost is high. Promotion Difficulty; during the dehydration process with medium-wave power, ohmic heating consumes a lot of energy, and short circuits are prone to occur when the water content is high, causing dehydration to be interrupted
