[en] Full text: The protection and corrosion resistance of steel in subsoil waters of Baku subway were investigated. Kinetic curves were drawn. The results obtained from the experiment coincide with calculated results. There have been revealed and proposed hudron and fuel oil mixture protecting steel from corrosion in subsoil waters (97.8%) for the internal surface of steel pipes
[en] This paper analyzes the role of price discovery of Shanghai fuel oil futures market by using methods, such as unit root test, co-integration test, error correction model, Granger causality test, impulse-response function and variance decomposition. The results showed that there exists a strong relationship between the spot price of Huangpu fuel oil spot market and the futures price of Shanghai fuel oil futures market. In addition, the Shanghai fuel oil futures market exhibits a highly effective price discovery function.
[en] Fuel oil is a refinery by-product with a big economical effect due to its high production volume, diluents use and market specifications based on low viscosity and low sulfur content. When these specifications are not achieved or they are not steady during the process, additional costs are generated by reprocessing, recirculation, storage, laboratory analysis, pumping, etc. An in-line viscosity automatic control, previously evaluated in a pilot plant, was installed in order to optimize the fuel oil preparation system. This type of control minimizes viscosity variation, maintains the product specifications and allows a proper dosage of diluents. The viscosity automatic control system has added several benefits as follows: decreases the diluents volume per day, decreases length of final products preparation, fewer number of samples to analyze, a more steady operation of plant, less sedimentation in storage tanks und mass und heat transfer processes more efficient
[en] Finland passed the bottom of the current recession last year, which was reflected in a growth in oil consumption, the first such growth to be seen for eight years. Despite the rise in sales volumes, competition in the marketplace has remained tough. Those in the industry have had to cut their costs significantly and enhance the efficiency of their distribution networks
[en] In this note we examine the relationship between the wellhead price of natural gas and institutional changes in the industry and other factors that influence this price. As part of this examination we estimate an equation to summarize the monthly relationship between the price of natural gas at the wellhead and the price of residual fuel oil and other variables between January 1987 and December 1991.

[en] A /MCM-41 superacid catalyst was prepared by impregnation and characterized by various methods. A novel procedure for oxidative desulfurization of simulated light fuel oil using K2FeO4 over /MCM-41 was developed. Fourier transform infrared spectroscopy (FTIR) and low-angle X-ray diffractometry (XRD) show that the material synthesized by the precipitation-sol-hydrothermal method is mobil composition of matter no. 41 (MCM-41). Thermogravimetry/differential thermal analysis (TG-DTA) shows that when the calcination temperature is higher than 300°.
[en] World oil statistics, in scope and accuracy, are often far from perfect. They can easily lead to misguided conclusions regarding the state of market fundamentals. Without proper attention directed at statistic caveats, the ensuing interpretation of oil market data opens the door to unnecessary volatility, and can distort perception of market fundamentals. Among the numerous caveats associated with the compilation of oil statistics, conversion factors, used to produce aggregated data, play a significant role. Interestingly enough, little attention is paid to conversion factors, i.e. to the relation between different units of measurement for oil. Additionally, the underlying information regarding the choice of a specific factor when trying to produce measurements of aggregated data remains scant. The aim of this paper is to shed some light on the impact of conversion factors for two commonly encountered issues, mass to volume equivalencies (barrels to tonnes) and for broad energy measures encountered in world oil statistics. This paper will seek to demonstrate how inappropriate and misused conversion factors can yield wildly varying results and ultimately distort oil statistics. Examples will show that while discrepancies in commonly used conversion factors may seem trivial, their impact on the assessment of a world oil balance is far from negligible. A unified and harmonised convention for conversion factors is necessary to achieve accurate comparisons and aggregate oil statistics for the benefit of both end-users and policy makers
[en] A utility company discovered soils in their plant contaminated with diesel fuel and related fuel oils (300-450 ppm). The soils were excavated and removed to a concrete pad for treatment. The authors conducted laboratory studies to determine if biostimulation or bioaugmentation would be appropriate for treating the soils. Microbial numbers and soil respiration were monitored in microcosms supplemented with: (1) organic nutrients, (2) inorganic nutrients, and (3) inorganic nutrients plus additional adapted microorganisms. Their studies indicated that biostimulation via the addition of inorganic nutrients would be appropriate at this site. Treatment cells for the contaminated soils were constructed. Initial data indicates that a 35% reduction in the concentration of contaminants has occurred within the first month of operation
[en] The computer has been worth its weight in gold to the fueloil man. In fact, with falling prices on both software and machines, the worth is greater than gold. Every so often, about every three years, we ask some questions about the utilization of computers. This time, we looked into the future, to find out the acceptance of other marvels such as the cellular phone and hand held computer. At the moment, there isn't much penetration. Contact by two-way radio as well as computing meters on trucks still reign supreme
[en] In the investigation, a crude from Cuban Northern Heavy Oil Belt and its fuel oil fraction was characterized by chemical and physical techniques. Subsequent to the characterization of the derivative, MSI gas analyzer was performed, to identify and quantify concentrations of chemical species, in correspondence with EPA (2007) for external sources. Total suspended particles collected in filter holder were identified using the gravimetric method (ISO 9096). With the intention of knowing the magnitude of polycyclic aromatic hydrocarbons reported in literature were chosen the higher and lower molecular mass and measured on the basis of its polar covalent radii. Total aromatic hydrocarbons were identified using activated charcoal with subsequent elution with nhexane for analysis by ultraviolet spectroscopy in a Genesys 10 UV spectrophotometer. Environmental pollution control in the oil sector, is evaluated in three states. The particles in the states mentioned above, whose dimensions are between (1-100) x10-9 meters are called nanoparticles. Nanotechnology currently offers firm steps in the development of different nanoparticles, which are applied directly to the mineralogical industry. Contributions stand out sharply operations: exploration, drilling and refining oil. (Author)
