Crude oil from the Chirag field

The crude oil from a promising new offshore field in Azerbaidzhan — Chirag — is light, low-sulfur, low-resin, and waxy. Its naphtha cuts are characterized by low octane numbers. They can be used as components of automotive gasolines. Brand KO-20 lamp kerosene can be obtained from light kerosene cuts. Catalytic dewaxing must be conducted on the 150–280°C cut to manufacture jet fuel. The diesel cuts are favorable feedstock for manufacturing summer diesel fuel. The potential content of base oils with a viscosity index of 75–89 is 24.64 wt. % in crude oil.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 6, pp. 35–38, November–December, 2004.

Alkyl Naphthalenes as Lubricant and Coolant Process Materials

Higher alkyl naphthalenes based on oligomers of propylene were investigated as lubricant and coolant process materials (LCPM). Dialkyl naphthalenes from the 280–420°C fraction of oligomers reduce the pressure of the metal on the roller in the subcritical region of rolling to a greater degree than monoderivatives. Products consisting of an equal mixture of mono- and dialkyl-substitution products ensure normal rolling conditions for copper.__________Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 4, pp. 34 – 36, July – August, 2005.

Efficiency of the Stage of Liquid-Phase Thermal Destruction of Petroleum Residues

Optimization of cracking process parameters, which determine the efficiency of the reaction volume, is the most important problem in creating industrial stages of thermal destruction of “native” petroleum residues – atmospheric and vacuum resids. A simplified approach to design of the reaction apparatus for refining such residues will result in large differences in these parameters during use and is due to insufficient information on the colloidal state of the feedstock mixture, kinetic characteristics of its conversion, and hydrodynamics of the material streams in the reaction volume.__________Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 3, pp. 24 – 26, May – June, 2005.
