The influence of total sediment of petroleum products on the corrosiveness of the metal of the tanks during storage

Abstract

Storage tanks for petroleum products must comply with the requirements of technical, technological and environmental safety. The corrosion rate increases with prolonged storage of petroleum products in tanks. To prevent the destruction processes for reliable operation of tanks caused by metal corrosion some solutions are needed. Active formation of general sludge occurs in the storage of fuel oil, which contains corrosion-active substances, because of the incompatibility of fuels. The paper assesses the effect of total oil sludge in tanks on the corrosion process and on the reliability of tanks. Studies of the formation of a common sediment caused by incompatibility when mixing petroleum products are conducted. The paper proposes a solution which allows to reduce the formation of total oil sludge and to ensure reliable operation of reservoirs.

Justification of the use of a vegetal additive to diesel fuel as a method of protecting underground personnel of coal mines from the impact of harmful emissions of diesel-hydraulic locomotives

“…Влияние вредных веществ отработанных газов на здоровье работников при различной концентрации наиболее подробно представлено в трудах А.Г.Чеботарёва [11,12]. Необходимость нормализации вредных выбросов в воздухе рабочих зон в угольных шахтах в связи со значительным превышением значением предельно допустимых концентраций описывается в трудах зарубежных ученых [38][39][40]. Многие ученые занимались изучением химического состава воздуха рабочих зон и физических характеристик двигателей ДГЛ до и после использования фильтров [13,18], альтернативного топлива [21,37] и различных модификаций двигателей [17,42].…”

Development of the Kinetic Equation of the Groove Corrosion Process for Predicting the Residual Life of Oil-Field Pipelines

“…According to existing estimations, more than 80 thousand accidents related to pipeline operation occur in Russia annually, and the majority of them are caused by corrosion processes [1,2]. In addition to field pipelines, hydrocarbon storage tanks [3], as well as main pipelines [4,5], are subject to corrosion. Corrosion failures are a subject of particular importance when considering the reliability of gas and oil pipelines, since even a single through defect leads to pipeline failure and, accordingly, an emergency situation, accompanied by a product spill or outflow, pollution of the environment, and large economic losses.…”

Influence of Asphaltenes on the Low-Sulphur Residual Marine Fuels’ Stability

“…Thus, obtaining LSFOs by selective compounding requires solving the problem of incompatibility arising when mixing the fuel components of paraffinic/naphthenic and asphaltene base [19,20]. As a result, marine fuel, as a multicomponent petroleum product, loses its sedimentation stability during storage and transportation and asphalt-resinousparaffin deposits (ARPDs) stratify, coagulate, and precipitate on pipelines and in storage tanks [21][22][23][24].…”

“…Besides the saturated aromatic compounds and resins, the residual petroleum fractions contain asphaltenes-high molecular weight carbon compounds that are generally identified as substances insoluble in normal alkane solvents, e.g., n-heptane (heptane-insoluble or HI); however, they are soluble in aromatic solvents [16][17][18]. Thus, obtaining LSFOs by selective compounding requires solving the problem of incompatibility arising when mixing the fuel components of paraffinic/naphthenic and asphaltene base [19,20]. As a result, marine fuel, as a multicomponent petroleum product, loses its sedimentation stability during storage and transportation and asphalt-resinousparaffin deposits (ARPDs) stratify, coagulate, and precipitate on pipelines and in storage tanks [21][22][23][24].…”
