Filterability Temperature

Obtaining winter diesel fuel is an expensive and complex process, in which paraffinic hydrocarbons are removed from the fuel. Today, the consumption of winter diesel fuel in Russia has reached its maximum, and the volume produced is not enough to meet the needs of the Russian market. Therefore, obtaining winter diesel fuel from summer grades, by adding a depressant additive, remains relevant. The most common depressants are ethylene vinyl acetate copolymers. The effectiveness of depressant-dispersant additives depends on the fractional and group hydrocarbon composition of diesel fuel. Also, the physicochemical characteristics of the paraffins contained in the fuel play an important roleDuring long-term storage of fuel, depressants do not prevent fuel stratification. Therefore, together with a depressant additive, a paraffin dispersant is used, the composition of such additives includes mainly amides and imides of mono- and dicarboxylic acids. Dewaxol 7801 depressant and dispersant additive is a specially selected composition based on surfactants and copolymers in a hydrocarbon solvent. The use of this additive makes it possible to improve the low-temperature performance of diesel fuel without affecting other properties. From the low-temperature properties of diesel fuel, we have chosen the limiting filterability temperature, since it is this temperature that characterizes the real working conditions. When the maximum filterability temperature is reached, the n-paraffin crystals reach sizes exceeding the pore diameters of the filters, the fuel is not pumped through the fine filters of the high-pressure fuel pump, and the fluidity of the fuel deteriorates. The article shows the effect of Dewaxol 7801, a depressant-dispersant additive, on summer diesel fuel, in various concentrations and when the fuel is heated from 40 to 60 degrees in steps of 10 degrees.

And Performance

A study of the hydrocarbon-type content of the base summer diesel fuels of various oil refineries in Russia was carried out using the methods of gas chromatography and high-performance liquid chromatography. It is shown that the experimental results obtained using these methods, namely the content of normal paraffinic, the total content of paraffin-naphthenic and aromatic hydrocarbons, do not provide sufficient information to predict the physicochemical and performance properties of diesel fuels. The method of two-dimensional gas chromatography-mass spectrometry was applied for a more detailed study of the hydrocarbon composition of diesel fuels, which made it possible to determine the ratio of normal and isoalkanes, the content of mono-, bi- and polycyclic naphthenic and aromatic hydrocarbons, and to explain the differences between fuels with similar performance characteristics.

The analysis of diesel fuels hydrocarbon composition before and after biodegradation is carried out by the methods of photocolorimetry. It was determinated, that the hydrocarbon composition of the diesel fuels is changed on influence of microorganisms. It has been shown that changes in composition hydrocarbons of diesel fuels and individual hydrocarbons in soil observe during growth of microorganisms on this soil.
