DAS CRUDE ANALYSIS

SUMMARY

The Narrow Cut TBP Distillation on “DAS CRUDE” crude was performed twice. In two

Runs 6000 ml (approx.) samples were used. The Primary Products Yield at the PRL cut

points are based on the average of the two Runs while detailed testing of these cut fractions was

carried out on the fractions obtained from the first and second Run. Gas oil and Residue yields

at revised cut points of 235-400 ºC and 400 ºC plus (revamp cut points) were also established.

The Test Method ASTM D-2892 was followed. The column used was of 50 mm diameter,

Tilting Funnel Type having 15 theoretical plates packed with Helipak packing. Each fraction

was weighed and specific gravity was determined at 60/60 ºF. The volume yields have been

calculated from the weight of each fraction and its respective specific gravity.

The DAS CRUDE Assay includes the following determinations:

Crude oil general characteristics.

TBP distillation for narrow cuts upto 371 ºC.

TBP distillation for narrow cuts upto 400 ºC.

TBP distillation into wide cuts corresponding to the following PRL cut fractions:

- Gas/LPG 0-40 ºC

- Light Naphtha 40-110 ºC

- Heavy Naphtha 110-145 ºC

- Kerosene 145-235 ºC

- Gas Oil 235-371 ºC

- Residue 371 ºC plus

- Gas Oil 235-400 ºC

- Residue 400 ºC plus

Detailed properties of all the above PRL cut fractions.
