CHROMATOGRAPHIC-MASS SPECTROMETRIC STUDY OF THE COMPOSITION OF EMISSIONS DURING THE LOADING OF PETROLEUM PRODUCTS
The composition of emissions during the loading of petroleum products using the methods of gas chromatography and gas chromatography-mass spectrometry were studied. It were shown that, depending on the time, stage of the tanker loading and the type of reloaded commodity petroleum products, concentrations and component composition in the air environment change significantly. Quantitative analysis was carried out using a portable gas chromatograph and analyzers, which allow for the rapid analytical control of contamination during the conduction of an overload. Taking into account the peculiarities of the composition of the sampled air samples, as well as their storage conditions, chromatography-mass spectrometric analysis was carried out on the day of selection, which allowed avoiding discrimination of the sample composition. It was noted that in accordance with the current regulatory documents regulating the control of the air environment in sanitary and industrial zones, it is recommended to identify certain substances and indicators that do not take into account the actual composition of the air mixture during the transshipment in different sections of the port territory. Based on the presented data, the expediency and efficiency of the use of recovery units, which allow reducing hydrocarbon emissions in air and costs associated with losses during the overload stage, is shown.
