Problems solved by technology

However, as the output of high-viscosity crude oil increases and the content of petroleum acid and organic sulfur (interface active substances) increases, the difficulty of electric dehydration increases, resulting in the increase of electric desalination (removal of CaCl 2 , MgCl 2 Salt) efficiency decreased significantly (> 3mg / L), resulting in increased corrosion of refinery process equipment
In 2001, the output of low-quality crude oil (high-acid, high-sulfur, high-viscosity crude oil) in China reached more than 85 million tons, exceeding the output of light crude oil by 78 million tons, of which the output of high-viscosity heavy oil was about 40 million tons. Some electric desalination and dehydration processes can no longer meet the needs of production

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] See figure 1 As shown, a high-frequency and high-pressure oil-water separation device of the present invention includes a power supply device, a mixing device, and a separation device. The separation device is an oil-water separation tank, which consists of a tank body 1 and a high-pressure introduction rod 12 arranged on the outside of the tank body 1, an oil outlet pipe 10, a water outlet pipe 9, an oil inlet pipe 5, a liquid level controller 14, and a tank body 1. The inner oil distribution pipe 6, the positive electrode plate 3, the negative electrode plate 4, the positive pole suspension beam 7, and the negative pole suspension beam 8 are formed. The two ends of the two electrode suspension beams are wrapped and fixed on the left and right ends of the tank body 1 by polytetrafluoroethylene or polyester plus glass fiber. The oil-water separa...

Abstract

A high-frequency and-voltage process for separating oil from water features that under the action of HF electric field, the emulsifier water microdrop is polarized and deformed to expose new active surface for easily and quickly becoming bigger drop until its diameter is greater than 100 microns. At this time, the water is quickly separated from oil. Its apparatus is composed of tank body, high-voltage rod, oil inlet and outlet tubes, water outlet tube, level controller, oil distributor, plate electrodes and suspending beam.

Description

technical field [0001] The invention relates to an oil-water separation device, which is a method and equipment for separating water from refined oil and crude oil by using a high-frequency electric field, especially a high-frequency and high-pressure oil-water separation method and equipment. Background technique [0002] Water is one of the most harmful pollutants in oil products. Salts in oil products are mainly dissolved in water. The existence of salt and water is the main cause of corrosion of equipment, pipelines and machines. [0003] Crude oil, extracted from oil wells, contains varying degrees of salt and water. The existence of these salts and water has caused great harm to crude oil processing and must be removed. Since most of the salts in crude oil are soluble in water, desalination of crude oil is carried out by removing salty water, that is, desalination and dehydration are carried out simultaneously. There are nearly 1,000 sets...
