Study of the Impact of Nonionic Additives on the Composition and Structure of Petroleum Dispersed Systems by IR Spectroscopy

The article describes a technique for obtaining a quantitative assessment of the composition and structure of the petroleum dispersed system (PDS) and its individual structural formations based on the data of the component composition and infrared spectroscopy. In the PDS of heavy petroleum feedstock modified with a mixture of unsaturated carboxylic acids and four atomic alcohols, the components of the core and the inner solvation shell are different in structure. The degree of affinity of the components of the inner and outer solvation shells of the complex structural unit (CSU), as well as that of the outer solvation shell and the hydrocarbon components of the dispersion medium, increases. Nonionic additives are involved, to a greater degree, in structuring the solvation shell of the CSU and also increase the degree of its affinity with the hydrocarbon components, which leads to an increase in the dispersion of the system and a decrease in its mobility.

TECHNOLOGY OF DEVELOPMENT OF COMPLEX STRUCTURAL DEPOSIT WITH APPLICATION OF IMPROVED MINING AGGREGATE

It is proposed to conduct selective extraction of conditioned and substandard ore of an exploded complex structural unit using an improved mining aggregate equipped with a classification grid with rotary grates and a crusher with an adjustable size of the discharge gap, which will allow one of the basic principles of resource saving - not to crush anything superfluous. The proposed technical and technological solution will significantly increase the productivity of mining operations, increase the extraction of mineral raw materials from the developed complex structural unit due to separation from substandard ore enriched with a useful component of ore fines, as well as reduce dusting and reduce the loss of mineral raw materials from blowing and spilling during loading and transportation.
