Real-liquid flowing electrical dewaterer evaluation device

Abstract

A real-liquid flowing electrical dewaterer evaluation device comprises a main housing provided with a coalescence module inside. The upper portion of the main housing is provided with a liquid collecting tube and a discharging port, the bottom of the main housing is provided with a drainage port, the outer side of the main housing is provided with a liquid distributing tube and a sampling device, one end of the main housing is provided with a stainless steel end cover, and the other end is provided with a transparent viewing window; the coalescence module comprises front and rear end plates and four layers of horizontal electrode plates installed between the front and rear end plates; the electrode plates are provided with bare electrodes, are made of 8mm stainless steel bars in a welded manner and are connected to high-voltage wires and grounded wires respectively; the housing is provided with a grounded wire. The oil-water separating effect is achieved through high electric field, and emulsion with few moisture flows out of a test machine after gathering through the liquid collecting tube for post treatment; the force for driving droplets to operate in the electric field is increased through the high electric field, the collision and coalescence of the droplets are enhanced, the oil-water separating speed is increased, the coalescence module is simple in structure, disassembling is facilitated, and efficiency is high.

Description

technical field [0001] The invention relates to a real-liquid flow electric dehydrator evaluation device, which is particularly suitable for evaluating traditional electric dehydrators, can screen out the optimal operating conditions, improve the stability of its operation, and provide the traditional electric dehydrator's operation. good reference. Background technique [0002] Crude oil produced from underground often contains a large amount of associated water, forming a crude oil emulsion. When crude oil and water form an emulsion, its properties change greatly, and its electrical conductivity, dielectric constant and viscosity are all higher than those of pure oil. These characteristics make crude oil dehydration very difficult. Crude oil emulsion has the following hazards: increasing the volume flow of produced fluid; deteriorating the performance of centrifugal pumps; increasing fuel consumption during the heating process; causing scaling and corrosion of metal pipes...

AI Technical Summary

Problems solved by technology

Oil-water separation methods include natural sedimentation, heating, chemical agents, centrifugation and electric dehydration, etc. However, the natural sedimentation period is too long, large-scale sedimentation equipment is required, the energy consumption of heating and dehydration is too high, chemicals affect the subsequent treatment of oil products, and the efficiency of centrifugal dehydration is low
