Condensate Oil with Simultaneous Determination of Some Characteristic
Physical Parameters

A method is developed for the analysis of associated
condensate by capillary gas chromatography (GC) with simultaneous
determination of its major physical characteristic parameters.
The method aims at the qualitative and quantitative determination
of C2–C36 alkanes, methylcyclopentane,
cyclohexane, methylcyclohexane, benzene, toluene, ethylbenzene,
xylenes, and 1,2,4-trimethylbenzene. This composition is according
to the petroleum companies demand. The method is used for the
simultaneous determination of the condensate average molecular
weight, density, carbon-to-hydrogen ratio, and boiling range.
The data obtained by the method has a good agreement with those
obtained by other methods. The literature methods cited later
used a simulated distillation method to obtain the hydrocarbon
distribution spectrum of the given condensate sample. The obtained
results revealed that the GC capillary method used is most rapid
and accurate for achieving the demanded analytical report.
