Model Emulsion

Oil emulsions are formed in the course of oil production, transportation, storage and a wash of oil tanks. Some oil emulsions are highly dispersed and rather stable for division by methods of upholding, centrifugation and flotation. In work for effective division of an oil model emulsion the method of a contact coalescention received the filtering loadings from a granular and porous polytetrafluoroethylene (PTFE). Speed of filtration of a model oil emulsion through the filtering loading depending on the size of granules of PTFE is determined. Extent of division of an emulsion at filtration through loading with a size of granules of 0,5 mm of high, 89% for porous and 74,4% for granular PTFE, but with increase in the size of granules of the filtering loading extent of division of an emulsion decreases. The initial model emulsion is polydisperse system with sizes of particles of 567 - 3315 nanometers. After filtration through PTFE granules the size of particles of a disperse phase decreases, particles of oil coalesce and are late in a time, in a surface and space between granules. It is confirmed by formation of oil slicks on the surface of the filtering loading. And the size of granules of the filtering loading is less; the size of particles in an emulsion filtrate is less. By results of a research influence of particle size distribution of the filtering loading on the size of particles of a disperse phase of a filtrate of an emulsion is defined.

Powder materials are widely used in the manufacture of electrochemical elements of thermal chemical sources of current. Electrochemical behavior of the powders depends on the shape and size of their particles. The results of the study of the microstructure and particles of the powders of vanadium (III), (V) oxides and lithium aluminate obtained by transmission electron and atomic force microscopy, X-ray diffraction and gas adsorption analyses are presented. It is found that the sizes of vanadium (III) and vanadium (V) oxide particles range within 70 – 600 and 40 – 350 nm, respectively. The size of the coherent-scattering regions of the vanadium oxide particles lies in the lower range limit which can be attributed to small size of the structural elements (crystallites). An average volumetric-surface diameter calculated on the basis of the surface specific area is close to the upper range limit which can be explained by the partial agglomeration of the powder particles. Unlike the vanadium oxide particles, the range of the particle size distribution of the lithium aluminate powder is narrower — 50 – 110 nm. The values of crystallite sizes are close to the maximum of the particle size distribution. Microstructural analysis showed that the particles in the samples of vanadium oxides have a rounded (V2O3) or elongated (V2O5) shape; whereas the particles of lithium aluminate powder exhibit lamellar structure. At the same time, for different batches of the same material, the particle size distribution is similar, which indicates the reproducibility of the technologies for their manufacture. The data obtained can be used to control the constancy of the particle size distribution of powder materials.
