Abstract

In this study, the coalescence of water droplets in crude oil under electric field was assessed numerically. The impact of different electrical field waveforms on the separation performance was evaluated. The pulsatile electric fields studied include sinusoidal, square wave, saw-tooth wave and triangular waves. In addition, the effect of several process conditions and emulsion properties on coalescence were assessed. The effect of electric potential (0-30kV), crude oil viscosity (10.6-212mPa.s), interfacial tension (20-250mN/m) and flow inlet velocity (10-100mm/s) under electric field application was investigated. The order of coalescence time followed: constant wave $\sim$ square wave < sinusoidal wave < saw-tooth wave $\sim$ triangular wave. The lowest performance for the coalescence was 160ms for saw-tooth and triangular waves. The energy consumed increased from 204. 8mJ to 5. 12J with the elevation of the applied electric potential from 2kV to 20kV. However, the consumed coalescence energy reduced to 2. SSJ at 30kV from 5. 12J at 20kV.

恒波脉动电场对原油乳状液中水滴聚结的影响

本文对电场作用下原油中水滴的聚并进行了数值模拟。评价了不同电场波形对分离性能的影响。研究的脉冲电场包括正弦波、方波、锯齿波和三角波。此外，还评价了几种工艺条件和乳液性能对聚并的影响。考察了电场作用下电势(0 ~ 30kv)、原油黏度(10.6 ~ 212mpa .s)、界面张力(20 ~ 250mn /m)和进口流速(10 ~ 100mm/s)的影响。合并时间的顺序为:恒波$\sim$方波<正弦波<锯齿波$\sim$三角波。锯齿波和三角波的聚结性能最低，为160ms。能量消耗从204增加。mj到5。12J，外加电势从2kV升高到20kV。然而，消耗的聚结能减少到2。从5到30kV的SSJ。12J在20kV。
