Рівень забруднення у пробах води нафтової промисловості

Organic toxic compounds such as polycyclic aromatic hydrocarbons, phenolic compounds are a global environmental concern as they cause inflammation and skin cancer. As you know there are two types of anthropogenic sources of hydrocarbons: petrogenic and pyrogenic sources. Petrogenic sources include crude oil and petroleum-derived hydrocarbon compounds. Pyrogenic sources of hydrocarbon compounds are formed as a result of incomplete combustion of organic substances such as oil, wood, coal. Before entering the open sea these oil products pass through the entire coastal zone. It is known that industrial waters are discharged into reservoirs after various chemical processes. The aim of this work was to determine how dangerous industrial oil water is when it enters the aquatic ecosystem. The article investigates the chemical composition of wastewater from the oil industry and identifies organic toxic compounds - polycyclic aromatic hydrocarbons and phenolic compounds. At the same time, the amount of heavy metals in water samples was analyzed. For chemical analysis, 3 samples were taken from the territory of the refinery. In total, 15 polycyclic aromatic hydrocarbons, 13 phenolic compounds and 9 heavy metals were analyzed in water samples. Water samples were analyzed in accordance with the contract HS-153/2-18 between Heydar Aliyev Oil Refinery and Baku State University's Department of Ecological Chemistry. The chemical analyses of heavy metals, polycyclic aromatic hydrocarbons and phenolic compounds were carried out using extremely sensitive devices such as Perkin Elmer ICP/OES-2100DV and GC-MSD gas chromatograph 6890N with a highly efficient mass-selective detector-Agilent 5975. In the Khazar Ecological Laboratory performed quantitative analysis of organic compounds in water samples as well as heavy metal determination.Органічні токсичні сполуки, такі як поліциклічні ароматичні вуглеводні та фенольні сполуки є глобальною екологічною проблемою, оскільки вони викликають запальні процеси та рак шкіри. Як відомо, антропогенні джерела вуглеводнів бувають двох типів: петрогенні та пірогенні. До петрогенних джерел відносяться сира нафта та отримані з нафти вуглеводневі сполуки. Пірогенне утворення вуглеводневих сполук відбувається в результаті неповного згоряння органічних речовин, таких як нафта, деревина, вугілля. Перед потраплянням у відкрите море ці нафтопродукти проходять через всю прибережну зону. Відомо, що промислові води скидаються у водойми після різних хімічних процесів. Метою цієї роботи було визначити, наскільки небезпечними є води нафтової промисловості для водних екосистем. У статті досліджено хімічний склад стічних вод нафтової промисловості та визначено вміст органічних токсичних сполук – поліциклічних ароматичних вуглеводнів та фенольних сполук. Також у пробах води досліджено вміст важких металів. Для хімічного аналізу було відібрано три проби з території нафтопереробного заводу. Загалом у пробах води визначено 15 поліциклічних ароматичних вуглеводнів, 13 фенольних сполук та 9 важких металів. Проби води аналізували відповідно до контракту HS-153/2-18 між нафтопереробним заводом імені Гейдара Алієва та кафедрою екологічної хімії Бакинського державного університету. Хімічний аналіз важких металів, поліциклічних ароматичних вуглеводнів і фенольних сполук проводився з використанням надзвичайно чутливих пристроїв, таких як Perkin Elmer ICP/OES-2100DV та газовий хроматограф GC-MSD 6890N з високоефективним мас селективним детектором Agilent 5975. Кількісний аналіз органічних сполук у пробах води, а також визначення важких металів було здійснено у Хазарській екологічній лабораторії

Modern methods for purifying phenol from waste water

С. Р. Гаджиева, Е. М. Гадирова. Современные методы очистки сточных вод от фенолаВ данной статье впервые проведена фотохимическая диссоциация фенола с наночастицами GO / TiO2, продолжительность снята на 1 час, а фотохимическая диссоциация с УФ-излучением раствора подтверждена. Кроме того, состав и количественный анализ раствора фотолиза для получения более точных результатов определяли методом газовой хроматографии, масс-спектроскопии и 40,8% разложение фенола было подтверждено

Economy of energy conservation

Such an agreement is possible in this case that the resource capabilities of the manufacturer and energy conservation of the consumers are considered simultaneously and on a unified basis. Investments should be directed to where minimal costs of produced or saved energy are ensured. With this approach, the demand for energy resources is provided at the cost-effective manner
