Abstract: During the transportation of the oil which is replaced from stratum by return water with demulsifier, the rheology of the water cut oil must have been affected. In order to study the influence rule of emulsion which contains hydrophilic demulsifier, we don this experiment which tests the different demulsifier using HAAKE Viscotester 550. The testing result showed that for crude oil emulsion, the effects of the factors on the rheological index and demulsifier evaluation index into corresponding relation, this provides the rheological field development significance; Demulsifier could move forward the emulsification diversion point, and the viscosity of the emulsion decreased effectively with different moisture contents. Different structure types of demulsifier have the different influence on viscosity. Finally, we conclude the influence rule of emulsion which provides the daterbase for crude oil heating airtight gathering and transportation technology .

In the study of the foundation of the oil / water wax deposition experiment, the emulsification characteristics of crude oil emulsion with high wax content have gradually become the hot research area. In the current research of emulsification characteristics of oil/water emulsion, the attention has been focused on the study of the effects of water cut, stirring speed, particle size distribution on the viscosity of waxy crude oil emulsion in the experiment, in which heavy oil and simulated oil are adopted as the working fluids. In this study, the emulsion with different water cut and stirred by different speed was prepared under three different temperature conditions, the temperature above the wax appearance temperature (WAT), near the WAT, and below the WAT. The polarization microscope and rotary viscometer were applied to measure the effects of the particle size of the dispersed phase and waxy crystal distribution on the oil/water emulsion viscosity. The results suggest that preparing the temperature for crude oil emulsion with high wax content has an important influence on the emulsion microstructure. This study lays the foundation for further study of oil/water two phase dynamic wax deposition experiments.

In this study oil-soluble (RP6000 and MAKS-9150) emulsion breakers have been selected for separation of water from Kirkuk / baba (50oC), Khbbaz (40oC) crude oil emulsions and their activity measured using the Bottle test method at different concentration and found the activity of RP6000 demulsified best than MAKS-9150 emulsion breakers. RP6000 separated water (100%) in (15)min., (40)ppm and in (60)min., (20)ppm of demulsified for Kirkuk/ baba Crude oil and for khbbaz Crude oil the (100%) water separation was in (15)min., (80)ppm and in (30)min., (60)ppm and PH effect, salinity, temperature and density of emulsion stability depending on literature were explained for Optimization.

Oil Spill Remediation

Chemical dispersants is one of the globally accepted remediation technique used for marine oil spill. However, the toxicity related with these dispersants confined its application in marine environment. Therefore, to overcome this problem, the employment of environmentally benign dispersants is one of the effective conceivable approach. In this study, the formulation comprised of choline based ionic liquid, choline laurate ([Cho][Lau]) and a biosurfactant, lactonic sophorolipids (LS) were used as a crude oil emulsifier. The toxicity of the newly developed formulation was evaluated to confirm their safe employment in sea water. The developed formulation worked effectively as a crude oil emulsifier and formed a stable crude oil emulsion. The toxicity study against Gram-positive and -negative bacteria depicts the “practically harmless” nature of the developed formulation. Thus, the results presented in this study showed that the new formulation can potentially replace the conventional dispersant used for marine oil spill remediation.
