Study of Commercial Products from Tomsk Oil
Abstract Generated abstract
This study evaluates the potential yield and quality of commercial petroleum products obtainable from crude oil of the Sovetsko-Sosninsko-Medvedevskoye field in Tomsk Oblast. The oil was fractionated by direct distillation using the ARN-2 method, and the resulting gasoline, jet fuel, kerosene, diesel, cracking feedstock, and lubricating oil fractions were characterized against relevant technical standards, with lubricating oil potential assessed by adsorption separation. The results indicate abundant low-sulfur gasoline fractions with low octane numbers, kerosene and diesel fractions meeting applicable specifications, and a favorable lubricating oil feedstock, with total distillate and residual oil yield at a viscosity index of 85 of about 15%.

In the present work, the potential content of commercial petroleum products in the oil of the Sovetsko-Sosninsko-Medvedevskoye field of Tomsk Oblast (well 18) was determined. For this purpose the oil was distilled in an ARN-2 apparatus according to the method of the All-Union Scientific Research Institute of the Petroleum Industry [1]. From the fractions obtained, petroleum products were blended and characterized in accordance with the requirements of the technical standards.

The results of the analyses are given in Tables 1–5. In the fraction boiling within the range 350–450°C, and in the residue, the potential content of lubricating oils was determined by the adsorption-separation method according to GOST 11244-65.

Curves of the dependence of the quality of distillate and residual oils on the depth of adsorption separation are presented in Figs. 1–2.
The gasoline fractions of this oil, obtained in large quantity, are low-sulfur, but, owing to the predominant content of methane hydrocarbons in them [2], are characterized by a low octane number. They can serve only as base components of commercial gasolines and jet fuels.

Kerosene distillates meet the requirements of the GOST standard for illuminating kerosene.
Diesel-fuel fractions taken in various temperature intervals satisfy the requirements of the technical specifications for summer diesel fuel for high-speed diesels.
The oil studied is a favorable feedstock for obtaining oils. The total yield of distillate and residual oils from it with a viscosity index of 85 is about 15%.
