Characterization and Property Correlations of Athabasca Bitumen Derived Synthetic Crude Oil
Narrow fractions of Athabasca bitumen derived synthetic crude oil (SCO) were prepared by distillation at 20℃ increment up to 500~C and characterized. The characteristics of naphtha fractions (IBP-130℃, IBP-180℃ and IBP-200℃), jet ,fuel fractions (130-230℃ and 160-240℃) and diesel fractions (180-320℃ and 230-350℃) were also determined. The SCO properties were correlated as a function of boiling temperature (T<,b>). This is useful for process design considerations such as optimizing operating conditions of refinery processing units. The viscosity (ν) of SCO fraction at various temperatures (T) can be expressed as: log(log(v+0.775)): exp(1.256+0.4179×log(T<,b>))-4.491×log T The acidity of SCO fraction (in mg KOH/1000 ml) showed a maximum at 350℃ and can be expressed as: Sulfur and nitrogen concentrations were below 10ppm in IBP-180~C fraction, but increased dramatically in fractions greater than 180℃. These can be expressed as: Suffur=exp(1. 650+6.317/(1+(exp-(T<.b>-549.205)/39. 410) ) ) Nitrogen=exp(l.844+6.340/(1+(exp-(T<,b>- 567.183)/58.150))) The SCO yield as a function of boiling temperature can be indirectly predicted using a 4<th> order polynomial of the density or refractive index, with O.038％ deviation. The properties of naphtha, jet fuel and diesel fractions can be predicted accurately by integrating the boiling point at 10, 30, 50, 70 and 90 v％ yield of each fraction.
