On October 6, 2002, M/V GOTIA, carrying 163 metric tons of fuel oil in her fuel tanks, rammed into the Emirgan Pier in the Bosporus. One of the fuel tanks started leaking oil in to the Bosporus. The ship continued its passage and finally anchored when it reached the Marmara Sea where the leaking tank was repaired. Following the accident, the strong surface current, rapidly transported the oil s...

Oil shale is a sedimentary rock that contains kerogen, a fossil organic material. Kerogen can be heated to produce oil and gas (retorted). This has traditionally been a CO2-intensive process. In this paper, the Shell in situ conversion process (ICP), which is a novel method of retorting oil shale in place, is analyzed. The ICP utilizes electricity to heat the underground shale over a period of ...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

The crude oil sector in Nigeria contributes substantially to the economy; however, these benefits are being compromised by significant subsidies on refined oil imports. The refined oil subsidy is paid primarily on imported fuel because domestic refineries cannot satisfy the national demand at current prices. Low fuel prices are considered an important benefit to the Nigerian people, where more ...

The global petroleum system is undergoing an “oil transition,” shifting from conventionally produced petroleum to a suite of substitutes for conventional petroleum (SCPs). This paper describes the Regional Optimization Model for Emissions from Oil Substitutes, or ROMEO, which models this oil transition. ROMEO models the dynamics of the transition to substitutes for oil and the environmental imp...

In this study, corn oil as vegetable oil, chicken fat and fleshing oil as animal fats were used to produce methyl ester in a biodiesel pilot plant. The FFA level of the corn oil was below 1% while those of animal fats were too high to produce biodiesel via base catalyst. Therefore, it was needed to perform pretreatment reaction for the animal fats. For this aim, sulfuric acid was used as cataly...

We attempt to determine the impact of production decisions on the price of heating oil. A model for the production of distillate fuel oil is proposed. Its solution, obtained using stochastic dynamic programming, closely matches history. By perturbing the problem in a deliberate manner, we can determine the value of additional units of inventory by examining diierences in costs. Using these diie...

A mobile, low-field nuclear magnetic resonance (NMR) sensor for onboard, inline detection of catalytic fines in fuel oil in the shipping industry is presented as an alternative to onshore laboratory measurements. Catalytic fines (called cat fines) are aluminosilicate zeolite catalysts utilized in the oil cracking process at refineries. When present in fuel oil, cat fines cause abrasive wear of ...

The high demand to replace the petroleum fuel makes renewable and sustainable sources such as Palm oil, Jatropha oil and Algae as main focus feedstock for biodiesel production in Malaysia. There are many studies conducted on Palm oil and Jatropha oil, however, the use of Algae as an alternative fuel is still in its infancy. Malaysia already implemented B5 based Palm oil as a feedstock and this ...

Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...
