Parameters often determined in crude oil include: density, API gravity, pour point, kinematic viscosity, percentage water content, salt content, sulphur content, asphaltene content, ASTM distillation cracking point as well as metal/mineral contents.
The ever-increasing chemical utilization of crude oils and petroleum products calls for a better knowledge of the composition, structure and properties of their fractions. Crude oil is a naturally occurring mixture, consisting predominantly of hydrocarbons, sulphur, nitrogen and metals ( Yasin et al., 2013). With a maximum crude oil production capacity of 2.5 million barrels per day, Nigeria ranks as Africa's largest producer of crude oil and the sixth largest oil producing country in the world this makes the country important to the world's energy market ( NNPC, 2015). Keywords: Resins Diluent Emulsion De-emulsification Xylene Crude oil Thus the solution of P:F de-emulsifiers in xylene enhances the de-emulsification of the Nigerian crude oil emulsions. This de-emulsifier obtained a water separation efficiency of 79% compared to the commercial de-emulsifier which gave 71% efficiency. From the analysis carried out, it was found that the most effective formulated de-emulsifier was obtained at formaldehyde to phenol (F:P) mole ratio of 1.8:1, 80% de-emulsifier concentration in xylene and residence time of 20 min. The results were analyzed and optimized using Minitab 16 utilizing a Pareto chart, normal effects, main effects and interaction plots.
A factorial design was done to determine the best combination of the de-emulsification conditions for the resolution of the Nigerian crude oil emulsion. The bottle test was carried out at an optimum temperature of 70 ☌, dosage of 50 ppm and residence times of 10 and 20 min. In this study, base-catalyzed phenol formaldehyde resins were formulated at varying formaldehyde to phenol ratios (1.2:1-1.8:1) the assessment was carried out by the bottle test method at varied de-emulsifier concentrations (vol/vol) in xylene acting as solvent diluent. This makes de-emulsifiers crude oil specific and thus gives rise to the continuous search for more and effective de-emulsifiers that can meet the specific needs of each locality.

Coupled with professional graph drawing features you can educate yourself and others about anything with this.The research and development of de-emulsifiers for separating water from crude oil emulsions usually result in varying degrees of success, depending on the location and the type of crude being treated. This includes Capability Analysis Graphical Analysis and Hypothesis Tests.
