    Dendroindication of petroleum soil contamination
    (Видавництво Львівської політехніки, 2021-06-01) Poberezhna, Liubov; Karavanovych, Khrystyna; Krekhovetska, Iryna; Ivano-Frankivsk National Technical University of Oil and Gas
    The main approaches to the detection of soil contamination by petroleum products using bioindication were analyzed. Necrosis of leaves of woody plants near sludge accumulators was recorded. To assess the possibility of dendroindication of soil contamination, 3 species of trees distributed on the territory of Bytkiv-Babchensky oil and gas field were selected. According to the results of the FisherSnedekor test, the influence of the concentration of oil products in the soil on the necrosis of tree leaves was confirmed, which confirms the possibility of using a dentroindication to detect soil contamination with oil products.

    Risk analysis of natural gas transportation processes
    (Видавництво Львівської політехніки, 2021-03-01) Mandryk, Oleg; Poberezhny, Liubomyr; Poberezhna, Liubov; Maniuk, Oksana; Maniuk, Mykhailo; Ivano-Frankivsk National Technical University of Oil and Gas
    The problem of ensuring technological reliability and environmental friendliness of the natural gas transportation process, the main approaches to risk assessment and management at industrial facilities are considered. To increase the troublefree operation of the gas transmission system, a comprehensive risk management system is proposed. The research of an ecological condition of the ground layer of air is being done in Bogorodchany district based on the constructed maps, which represent a distribution of harmful matters concentrations, its coefficients and also the coefficients of ecological danger and the map of a total contaminating index. The general chart of ecological risk is represented. Analysis of objects for gas transportation is made. The method of area detonating calculation and distance of mixture explosive cloud distribution is considered during the damage at the main gas pipeline. Area detonating calculations and the distance of mixture explosive cloud distribution are conducted at different wind speeds.
