Comparative analysis of in-line monitoring methods to determine the boundaries of the mixture region of petroleum products transported by serial transfer has been carried out. It has been found that the most promising method is infrared spectroscopy (IR spectroscopy) based on the absorption, reflection and dispersion of infrared energy. Currently, the use of IR spectroscopy for analyzing petroleum products is limited by an insufficient number of indirect methods for identifying and determining the structural fragments of hydrocarbon and non-hydrocarbon compounds. Experimental studies to assess the possibility of applying IR spectroscopy as a rapid method for determining the boundaries of mixture regions of various grades of petroleum products have been conducted. The purpose of the research: quantifying variations of IR spectra obtained from the analyzed test samples depending on the concentration of a certain grade of petroleum product in a petroleum product with a different hydrocarbon composition. The subject of the research: samples of AI-95 commercial motor gasoline (AB), inter-season diesel fuel (DT), TS-1 aviation kerosene (AK), and 1:1 ratio paired mixture thereof. The experimental results confirmed the high sensitivity of the IR spectroscopy method in determining changes to the hydrocarbon composition of petroleum product mixtures depending on the concentration thereof, which means a key conclusion about the possibi-lity of its use in controlling the mixing process of petroleum productstransported by serial transfer can be drawn. |
