IN SIGHT

Fokina E.N.
State of the Russian refineries. The situation analysis
Keywords: gasoline, investments, oil, fuel production volume, technical regulations.
Oil processing in Russia is provided now by 27 large and nearby 50 small refineries. And only two large plants are on-stream for less than 40 years. Twelve refineries are operated more than 60 years, eight more have celebrated semicentennial anniversaries. Age of the facilities shows distinctly, how actual the refineries modernisation problem is. In the article the situation around modern Russian refineries is analysed.

PRODUCTS and TECHNIQUES

Andrew R. Tyas (DuPont Clean Technologies)
Diesel Hydrotreating and Mild Hydrocracking using DuPont ™ IsoTherming® Technology
Keywords: hydrotreatment, traditional production engineering, IsoTherming®, Diesel fuel, light hydrocracking.
A short general description of the IsoTherming® Technology is presented, its advantages as compared to traditional hydrotreatment solutions in terms of operation and investment costs are observed. Some instances are shown, of how the proposed production engineering can be, and has been used for the solution of specific goals at oil refining enterprises in hydrotreatment, concerning Diesel fuel production units with ultralow sulphur content, and also light hydrocracking units.

Design and construction solutions for hydrosulphuric gas utilisation unit at the Achinskiy NPZ VNK Open Society
Keywords: Claus process, sulphur production, conversion, equipment.
Production engineering of gas bursts purification and positive utilisation of industrial wastes is a priority line to modern enterprises. The Claus process remains today a basic industrial method of hydrogen sulphide removal from natural and refining gases. Technological and ecological indexes of sulphur production processes do not meet modern demands of production development. Thus, upgrading the Claus process to solve these problems is an actual way for gas and oil refining industry.

Mel'nikov V.G.
Influence of lube oil viscosity and rolling speed upon rapidity limit and thickness of lubricant layer in UGD contacts
Keywords: resilient-hydrodynamic contact, Newtonian viscosity, thickness of lubricant layer, rapidity limit, hydrodynamic effect, centrifugal force, contact-hydrodynamic theory, oil starvation regime.
The factors which influence the shaping of a lubricant layer in concentrated resilient-hydrodynamic contact (UGD) contacts are analysed. Lubricant layer thickness of a Newtonian fluid is influenced simultaneously by two differently oriented factors: hydrodynamic effect, and the centrifugal force, expelling oil from friction zone. The first factor is proportional to total velocity, the second to a square of total velocity. When the total velocity is high enough, lubricant layer thickness drops as a result of a lag of oil flow velocity into contact, compared to the running-on velocity of the following ball deforming a lubricant layer. More viscous oils show the aberration from Newtonian rheology at smaller total velocity.

Tsvetkov O.N.
Supplying high-grade base oils to the domestic motor oils production industry
Keywords: base oils, motor oils, hydroconversion, hydroisomerization, hydrocracking.
Short survey of domestic motor oils production state and production prospects of oils for automotive engineering of the fourth and fifth ecological class is presented.

QUALITY: DOCUMENTS and COMMENTS

Seryozhenkin A.M.
Prospects of motor pool development in Russia and modern demands to motor fuels
Keywords: motor pool, engine fuel, technical regulations, enactment term.
A forecast of motor pool development is observed, and an appraisal of essential consequences of automotive fuels production delay of appropriate ecology classes, in point of enactment of regulations on harmful bursts for produced in Russia and imported automotive engineering is given.
