Embodiment 1

[0033] This embodiment provides a treatment system for emulsified aged crude oil, comprising a reaction separation skid 21, a solid-liquid separation skid 22, and a purification separation skid 23. The upper outlet of the reaction separation skid 21 is connected to the solid-liquid separation skid 22, purification The separation skid 23 is connected, the bottom outlet of the reaction separation skid 21 is connected with the solid-liquid separation skid 22 through a pipeline, and the water outlet of the purification separation skid 23 is connected with the solid-liquid separation skid 22 through a pipeline.

[0034] The reaction separation skid 21 is used for the separation of oil, suspended sludge and water, the solid-liquid separation skid 22 can realize solid-liquid separation, and the purification separation skid 23 can realize the quality of oil and water reaching the standard.

Embodiment 2

[0036] On the basis of embodiment 1, this embodiment provides a kind of figure 1 In the emulsified aged crude oil treatment system shown, the reaction separation skid 21 includes a skid base I and a heat exchanger 3 located on the skid base I, a stirring tank 4, a reaction tank 5, a dosing device A6 and a dosing device B 7 , the dosing device A6 is communicated with the emulsified aged crude oil inlet, the emulsified aged crude oil inlet, the heat exchanger 3, the stirring tank 4, and the reaction tank 5 are sequentially communicated, and the dosing device B7 is communicated with the stirred tank 4, and the The reaction tank 5 is provided with a honeycomb filler (ZY-03 material), which is composed of a hydrophilic and oleophobic base layer and an oleophilic and hydrophobic surface coating, and the oleophilic and hydrophobic surface coating is coated on the hydrophilic and oleophobic base. The diameter of the honeycomb filler is 50mm. This material can slow down the moving spee...

Embodiment 3

[0046] On the basis of embodiment 1 or embodiment 2, this embodiment provides a kind of emulsified aging crude oil processing system, also comprises sludge bagging vehicle and treatment field anti-seepage ground layer, and described sludge bagging vehicle is used for coordinating The solid-liquid separation skid 22, the reaction separation skid 21, the solid-liquid separation skid 22 and the purification separation skid 23 are all arranged on the anti-seepage ground layer of the treatment field, and the anti-seepage ground layer of the treatment field is polyurethane with a relative molecular mass greater than 10,000 .

Abstract

The invention provides an emulsified aged crude oil treatment system and an emulsified aged crude oil treatment method. The emulsified aged crude oil treatment system comprises a reaction separation pry, a solid-liquid separation pry and a purification separation pry, wherein an upper outlet of the reaction separation pry is communicated with the solid-liquid separation pry and the purification separation pry through pipes respectively; a bottom outlet of the reaction separation pry is communicated with the solid-liquid separation pry through a pipe; a water outlet of the purification separation pry is connected with the solid-liquid separation pry through a pipe. The emulsified aged crude oil treatment system is high in integration, convenient to move, simple in technological process, easy to operate and low in cost; compared with the prior art, the emulsified aged crude oil treatment system has the advantage of strong applicability, and is applicable to most of emulsified aged oil treatment. The moisture content of the treated crude oil can be controlled within the range being lower than or equal to 0.5-1%; the treated water can be directly reinjected and does not need to reentera water treatment system, so that the treatment process can be reduced and the cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of oilfield environmental protection, and in particular relates to an emulsified aging crude oil treatment system and treatment method. Background technique [0002] Emulsified and aged crude oil widely exists in oil field gathering and transportation and petroleum refining and chemical systems. Timely recovery and efficient treatment of aged oil is of great significance for saving energy, reducing the pressure of sewage treatment and gathering and transportation systems, solving the problem of sewage water quality deterioration, and reducing safety and environmental hazards. Important environmental, social and economic benefits. [0003] With the extension of oilfield development time, joint development of multi-layer systems, and more measures for oil and water wells, etc., the emulsified oil (aging oil) in the combined station and dehydration station is gradually increasing, which seriously affects the no...
