“…Thermal desorption can be classified as low temperature thermal desorption or high temperature thermal desorption, and the remedial process includes the heating (direct or indirect) of the contaminated environmental matrix at an appropriate temperature in a vacuum or carrier gas system to separate target volatile or semivolatile contaminants from the matrix [22]. In thermal desorption, the boundary between high and low temperatures is not clear, but it is classified as around 300-350 °C.…”

Oil-contaminated soils from a former landfill and gas station site in Korea were treated by thermal desorption. The removal efficiencies of the different oil components such as total petroleum hydrocarbons (TPH), polyaromatic hydrocarbons (PAHs), unresolved complex mixtures (UCM), and alkylated PAHs (Alk-PAHs) by thermal desorption were determined. The effects of temperatures (200, 400, and 600 °C) and treatment times (15, 30, 45, and 60 min) on the thermal desorption efficiency were studied. The treatment efficiency increased with increasing temperature from 200 to 400 °C and with increasing treatment time. Almost complete removals of TPH, UCM, PAHs, and Alk-PAHs were observed after 15 min at 400 °C. The treatment temperatures of 400 and 600 °C did not show a significant difference (p-value > 0.05). Overall, this study shows that the different components of oil in the oil-contaminated soils can be treated effectively in a relatively short time by thermal desorption, and such high removal efficiency in a relatively short time for the oil-contaminated soils can be of advantage for the treatment of highly contaminated or weathered soils where biological treatment efficiency is low.

“…The in situ or ex situ thermal treatment method has been widely used to remediate PHC-polluted soil due to its rapid treatment, high efficiency, and wide adaptability. Several studies have concluded that the thermal treatment temperature and duration are two key factors affecting the remediation efficiency. − Falciglia et al showed that the residual diesel concentration in sandy and silty soil can be reduced to about 10 mg/kg at 250 °C for 5 min, while higher temperatures (about 300 °C) or longer treatment times were required for clay. Ren et al thermally treated diesel-contaminated soil and found that the removal of total petroleum hydrocarbons (TPHs) was 28% at 100 °C for 120 min, increasing to 94% at 250 °C for 10 min.…”

The remediation of petroleum hydrocarbon-polluted soil with microwave irradiation is a promising technology due to its high decontamination efficiency and low energy consumption. The current study is to experimentally investigate the performance of microwave heating remediation of light and heavy crude oil-contaminated soil in a lab-scale apparatus. The results show that 98.95 and 96.39% of total petroleum hydrocarbons (TPHs) in light and heavy crude oil-contaminated soil can be removed in 15 and 20 min at 1000 W, while the residual TPHs constitute around 143.2 and 401.4 mg/kg, respectively. This indicates that the removal of light crude oil from soil is much more efficient and consumes less energy due to the difference in removing behaviors for different fractions. The major removal of C10−C16, C16−C22, and C22−C40 fractions at 200, 300, and 400 °C reveals that the removal of both small and large molecular fractions is promoted by microwave irradiation as it occurs at a temperature far below their boiling points. Moreover, soil organic matter (SOM) in light and heavy crude oilcontaminated soil is maintained at a moderate level (i.e., 19 and 21.7 g/kg at 400 °C) after microwave treatment, giving an opportunity for soil reusability.

“…Our study focuses on causes that lead to other causes that will cause accidents, and by occurring the same first causes, a prediction class will be discovered. Oil is one of the most important and dangerous fields in our lives as one mistake not only leads to money loss but also leads to a lot of other life losses such as marine life, birds' life, sea creatures, and the most sensitive and costly human life as explained in [1], [2]. Each one of them is so important and affects the world in all its lives, such as the economy and reputation of those who fear working in the oil fields; a field without people to work on is no field; oil controls the world; most of the machines are working with oil and gas, and all the kings of oil extraction and transforming.…”

<span>This study discusses the problem of oil and gas faults that lead to spills or explosions that lead to a lot of losses in human life, oil field extraction, and costs. Petrol is an important field in our lives because it controls all aspects of human life and their way of life, so our research focused on petrol and its problems in order to introduce a better way of life. The data used in this research was taken from the 3w database that was prepared by Petrobras, the Brazilian oil holding. The 9 classes classified in that work include the normal state that indicates the factors that will not lead to a problem. Deep learning classification techniques were used in this study. 99% accuracy was obtained in that model, and it refers to a successful prediction and classification of each class. Different results were observed when different hidden layers, optimizers, neurons, epochs, and activation functions were used. 99% was achieved when using Adam's optimizer and Tanh's activation function.</span>
