SORPTION OF PETROLEUM HYDROCARBONS AND HYDROCARBON-OXIDIZING

MICROORGANISMS WITH ORGANOMODIFIED AND INORGANIC SORBENTST

The possibility of using inorganic sorbents (sand, silica gel, zeolite-containing rocks (ZCR)) and their organomodified derivatives for binding of benzene and bacteria Escherichia Coli in aqueous environment was studied.
It was found that the ZCR and silica gel show a weak activity against sorption of benzene, but high activity against E. Coli cells. Surface modification of silica gel and sand by organic polymers leads to a significant increase in their sorption capacity with respect to benzene, dissolved in water. At the same time, the sorption of E. Coli cells on organomodified sorbents is negligible. Sorption of E. Coli cells and benzene is largely determined by the surface area of sorbents. ZCR and silica gel can be recommended for further testing in order to clean the contaminated water environments as sorbents of pathogenic and conditionally pathogenic microorganisms. Sorbents on the basis of inorganic carriers and polymeric modifiers can be used for cleaning of the soil and groundwater polluted by benzene and its homologs.

Key words: hydrocarbons, bacteria, soil, groundwater, contamination, clean-up, remediation, sorption.

TECHNOLOGY FOR HEAVY OIL DEWATERING BY WATER EVAPORATION

The paper presents the research on the process of breaking highly-stable heavy oil emulsions by water evaporation. An equation has been derived and relevant curves have been plotted to calculate the required heating temperature. This study shows the dependence of hydrocarbon distillate yield on heating temperature, boiling point oil composition and the initial water cut of the emulsion. The technology of heavy oil dehydration has been field tested using oil from the Mordovo-Karmalskoye field.

Key words: highly-stable heavy oil emulsions, dewatering, water evaporation, heating temperature, hydrocarbon distillate yield, crude oil treatment technology.

STUDY ON CHEMICAL COMPOSITION OF VACUUM DISTILLATES AND THEIR

REASONABLE REFINING

SARA composition and other characteristics of vacuum distillates from different crude distillation units are studied.
It is established that all the distillates have broad boiling range. The distillates SARA composition was compared with the main viscosity-temperature characteristic of lubes, that is viscosity index. It was determined that, when utilizing the mentioned distillates to produce fuels, flow charts including purification the distillates from sulfur compounds are preferential. At the same time, when utilizing the mentioned distillates for production of lubes, which meet API specifications, more sharp fractionation at the first step with further hydrogenation processing within a general flow chart of lube production are required.

Key words: vacuum distillate, SARA composition, aromatic hydrocarbons, sulfur content.

SUPPORTED HETEROPOLY ACIDS AS CATALYSTS FOR PARAFFIN ISOMERIZATION

The results of n-hexane isomerization at temperature range 300350C are presented. Silica supported P-Mo, P-W, Si-Mo and Si-W type heteropoly acids (HPA) were applied as catalysts, in which peripheral atoms were Mo and W, and central atoms were P and Si.
The optimum quantity of HPA supported on silica gel, and optimum concentration of modifiers were indicated. W-type HPA demonstrates higher activity in isomerization reaction, then Mo-type HPA, which is especially noticeable at simultaneous exchange of phosphorous ion to silica ion in heteropolyanion. HSiW demonstrates the greatest activity among tested catalysts. Introduction of Ni ions to silica supported HPA samples increase their catalytic activity with respect to isomerization products formation. Substantial increase of catalytic activity observed for Si-W HPA is due to higher acidity than that of other HPA samples. Introduction of Ni enhance the rate of dehydration stage of entire isomerization process to form surface hydrogen atoms.

Key words: heterogeneous catalysis, isomerization, n-hexane, supported heteropoly acids.

AN APPROACH TO PREDICTION OF OIL THEFT FROM PIPELINES

Problem of oil theft from pipelines is critical in several regions of Russia. That is why a new method for modeling oil theft-protection struggle based on population dynamics approach is proposed. It allows making short-term predictions of oil theft activity. Model could be used on regional, state, or corporate level. It allows to compare an economic efficiency of competing pipeline defense strategies.

The model also takes into consideration implicit consequences of choosing one of these strategies.

Adequacy of the model is verified using oil theft statistics of Samara Region.

Key words: crime, population dynamics, mathematical model, defense strategy, tap, economic efficiency, prediction.
