Abstract

This technical paper evaluates de-emulsification and rheological verification of Nigerian light crude oil emulsion viscosity using statistic model. The light crude oil which is paraffin base, of low wax content was emulsified with brine solution to obtain stable emulsion before deemulsification with heavy alkylbenzene sulfonate. The measurements of the viscosity of the emulsion before and after water separation were carried out using rotational viscometer. Model prediction coefficients of emulsion viscosity, using shear stress and concentrations relationship was established by application of statistical analysis of statistic software version (6). The graphs of observed data versus predicted, shear stress and shear rate data, measured values and predicted values were plotted respectively and 99.954% was obtained as correlation co-efficient. Also, from statistical analysis modeling, the flow behavior index of light crude oil emulsion viscosity is 0.99701, which is approximately 1, which shows the Newtonian fluid behavior.
