Emulsified aged crude oil treatment system and treatment method

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...
