Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The invention is a high-frequency electric coalescence type high-efficiency oil-gas-water three-phase separator. The tank body needs to be treated with anticorrosion and heat preservation, and the internal components are made of stainless steel. Depending on the processing capacity, 3 to 10 cyclone tubes with a diameter of 50-100mm are arranged inside the cyclone.

[0022] Such as Figure 1 to Figure 2 As shown, the high-frequency electric coalescence high-efficiency oil-gas-water three-phase separator includes a base (1), a cyclone (2), a horizontal tank (3), and a sewage system (4).

[0023] Both the cyclone (2) and the horizontal tank (3) are placed on the base (1); the cyclone (2) is placed on the inlet side of the horizontal tank (3) for pre-separation of oil and water, A large amount of free water present in the crude oil is separated to reduce...

Abstract

The invention provides a high-frequency electric coalescence type high-efficiency oil-gas-water three-phase separator. The separator comprises the following components: a base (1), a cyclone (2), a horizontal tank (3) and a pollution discharge system. The cyclone (2) is placed at an inlet side of the horizontal tank (3), and a cyclone oil phase outlet (5) is connected to a separating cylinder inlet (24); the horizontal tank (3) is separated into a primary separation chamber (8), a settling chamber (9), an electric dehydration chamber (10), an oil chamber (11), and a water chamber (12); and the pollution discharge system (4) is connected to a cyclone water outlet (6) and a water outlet (16). The volume of the separator tank is effectively reduced, and the separator has the advantages of compact structure, high dehydration efficiency, etc. The phenomenon 'reserved electric field' which is easy to appear in conventional electric dehydrators is overcome, and at the same the problem that the treatment effects do not reach the standard existed in the conventional oil-gas-water three-phase flow separator is solved.

Description

technical field [0001] The invention belongs to the technical field of petroleum gathering and transportation, and is especially suitable for the dehydration treatment of crude oil with high water content, aging oil and crude oil containing high polymer and demulsifier. Background technique [0002] At present, when crude oil is dehydrated in oil fields, conventional dehydration processes and separators are generally used. In order to effectively separate oil, gas and water, a large-volume separator tank must be used, which not only increases the cost of crude oil dehydration equipment, but also has complex dehydration process, low equipment utilization rate, and large equipment footprint. Contents of the invention [0003] The invention provides a high-frequency electric coalescence type high-efficiency oil-gas-water three-phase separator, which effectively reduces the size of the separator tank, realizes the integrated design of crude oil dehydration equipment, simplifie...
