Emulsion can be defined as a system, whereby one immiscible liquid phase is dispersed as globules (dispersed phase) in the second phase of immiscible liquid (continuous phase) (Lim et al., 2015).There are three types of emulsions: they are, water-in-oil (W/O) emulsion, oil-in-water (O/W) emulsion and multiple emulsion.Web

1. Introduction. Electric field-mediated coalescence of conducting water droplets dispersed in a continuous, poorly conducting dielectric oil phase (Figure Figure1 1) is a long-standing technology in the petroleum refining industry.This technology has been used to remove emulsion droplets of water in crude oil, 1−7 particularly in the context of …Web

The system was designed without optimization of the emulsion flow pattern. By applying an electrostatic field of 2 kV/cm, improvement in the destabilization of the tested emulsions was observed, yet the electrocoalescer was unable to decrease the water content down to crude oil export specifications. It appears that the electrocoalescer …Web

1 Introduction. Crude oil is typically extracted with dispersed water in varying concentrations. The Water-in-Oil (W/O) emulsions are believed to be initially formed during the migration of oil and water through the porous reservoir rocks to the production wells [] and subsequent transport to production facilities for phase separation.Pressure drop …Web

Abstract To assure a smooth and cost-efficient flow of crude oil emulsion from wells to a production facility, the oil industry relies heavily on the prediction of viscosity in pipe. The physical expression of this viscosity depends on a subjective estimate of a maximum packing volume fraction (compacity), ranging between 58 and 74 vol%. This …Web

The emulsion samples left to stand are observed and the results are depicted in Fig. 2 a. Obviously, aqueous-phase pH affects the emulsion stability. For acidic medium, the separated water volume varies from 3 vol.% to 36 vol.% as water pH varies from 1 to 6.The largest volume (36%) is reached at pH = 6.In the basic medium (pH = 8–13), …Web

The stable oil–water emulsion phase is formed between the light liquid phase and the heavy liquid phase. The oil–water emulsions will bring a series of problems to the subsequent oil separation and processing processes, such as increase processing cost, corrode pipeline and equipment, reduce oil quality, pollute environment etc.Web
