this research studies the application of hybrid algorithms for predicting the prices of crude oil. brent crude oil price data and hybrid intelligent algorithm (time delay neural network, probabilistic neural network, and fuzzy logic) were used to build intelligent decision support systems for predicting crude oil prices. the proposed model was able to predict future crude oil prices from august...

The subject of petroleum storage tank fires has gained a great deal of attention due to the high cost of petroleum, and the consequent disruption of petroleum production; therefore, much of the current research has focused on petroleum storage tank fires. Also, the number of petroleum tank fires is oscillating between 15 and 20 fires per year. About 33% of all tank fires are attributed to light...

The recent expansion in the production of shale petroleum crude oil, combined with the lack of new pipeline construction, has placed the railroads at the center stage for safe and efficient transport of very large volumes of this commodity. Petroleum crude oil poses fire risk in the event of train accidents. The consequence modeling based on the US DOT Emergency Response Guidebook (ERG) or ALOH...

LPG (Liquefied Petroleum Gas) is a petroleum derived, colorless gas, typically comprised of mainly propane, butane, or a combination of these two constituents. LPG fuel for vehicles is actually a mixture of various hydrocarbons which are gases at atmospheric pressure and temperature but which liquefy at higher pressures like less than 200 psi. LPG is a natural derivative of both natural gas and...

In the petrochemical industry, certain elements are known to impact the performance and value of the final product, while others have detrimental effects on petroleum refining processes, as in the case of elements which can deactivate or poison catalysts. Consequently, there are several ASTM methods on the elemental analysis of oils, lubricants and fuels. Multi-Element Analysis of Petroleum Cru...

One of the most important anthropogenic pollution types in countries with oil production is soil and water contamination by petroleum. Phytoremediation is an emerging green technology for cleaning up polluted soil. A greenhouse experiment was conducted to study the effect of oil-contaminated soil on Echinacea purpurea with four concentrations of crude oil - contaminated soil: control = 0, 0.5% ...

Fractionation of petroleum ether partitioned ethanol extract and crude petroleum ether extract of the leaves of Murraya koenigii Linn (Rutaceae) led to the isolation of 5,8-dimethyl furanocoumarin (1) and 1-al, 3[6’, 6’ dimethyl 5-hexene] carbazole (2) and β-sitosterol (3). Their structures were elucidated by spectroscopic methods such as UV, IR, NMR and LCMS. All the compounds were isolated fo...

Currently, petroleum hydrocarbons are the most abundantly used chemicals in the world. Manufactured from crude oil, petroleum hydrocarbons are found in gasoline, kerosene, fuel oil, asphalt, and even some chemicals used in home or at work. Almost every person on this planet has once or more used a petroleum product or byproduct. Due to their wide de mand, they are transported all over the world...

Corporate social responsibility information disclosure's late start in China, both in quantity and quality needs to be improved. This shell and PetroChina from 2013 respectively published by the sustainability report for analysis, according to disclosure forms, content, management bodies and the guidelines for the preparation of the report compared the four aspects. Recommended China Petroleum ...
