RESEARCH OF HYDROCARBON COMPOSITION AND PHYSICAL AND CHEMICAL PROPERTIES OF LIGHT DISTILLATE FRACTIONS OF CASPIAN OIL

This article presents the results of a study of the physical and chemical properties and individual hydrocarbon composition of gasoline and kerosene-gas oil fractions of the Caspian field, Atyrau region. The detailed group hydrocarbon composition and commodity physical and chemical characteristics of gasoline, kerosene and diesel fractions are determined, as well as the influence of the parameters of the main technological factors temperature, pressure and volume feed rate of raw materials on the output and quality of the target product. The optimal variant of its processing with the production of commodity oil products is proposed. It is shown that the Caspian oil field paraffin medium, mainly consists of light hydrocarbons with high yields of gasoline fractions (36,2% wt.) and with a high content of hydrogen sulfide, sulfide and light mercaptan sulfur compounds, which require a special approach to their effective processing, and shows that in the process gidroliticheski processing of the received oil of the mixture oil of the Caspian Deposit significantly improves the physical and chemical properties: reduces sulfur, nitrogen and oxygen compounds. Light gasoline fraction (boiling point 62°C ) Caspian oil is effectively used as a valuable raw material for the process of catalytic cracking at existing refineries of the Republic of Kazakhstan as a raw material for the process of catalytic isomerization, and the resulting product-isomerize is used as a component of commercial high-octane environmentally friendly automobile gasoline and for the production of hydrocarbon solvents, kerosene and diesel fractions, and after their hydrocatalytic processing is used as a component for the production of jet and diesel fuel.
