... to the blank emulsified crude oil B. Effect of Demulsifier on Wax Deposition The effect of the used demulsifier : Basorol E 2032 to reduce the wax deposition was more successful for crude oil A reducing the wax dimensionless thickness from 0.070 (L/L) when no demulsifier wax used to dimensionless wax...

... of demulsifiers. In resolving emulsions, heat, chemical or a combination of both methods can be used. In this study, synthetic emulsions in water-to-oil phase ratios (WOR) of 20/80 and 50/50 were resolved separately with heat generated from microwave oven, chemical demulsifiers and their combination. Results...

... demulsifiers for the treatment of crude oil emulsion. This water interferes with refining operations, provoke corrosions, increase heat capacity and reduce the handling capacity of refining equipment and pipelines. Four samples of crude oil emulsion were collected from Ughelli East stations W/10L, W/10L, W/8L...

... in breaking crude oil emulsion. Wells 2L and 4L were used for the analysis. Crude samples were obtained at the upstream of chemical injection points to ensure the samples were true representatives of the crude from the wells in the field. Chemical demulsifiers (DM1, DM3, DM4, and DM5) were formulated...

...°C), but many of the inhibitors exhibited poor performance at low temperatures (below 10°C), with wax inhibition percentage as low as -8%. Addition of demulsifier to the solution of the oil and the polymer was found to improve the wax inhibiting ability. The overall average wax inhibition (OAWI...

Paper Number: SPE-167528-MS
...Conclusions Locally formulated demulsifiers can be highly effective with low separation time in separating oil from water in oil-water emulsions. All blends spontaneously resolved the emulsion in the crude oil sample producing nearly 100% dry crude oil with trace elements. Some locally...
