The oil palm, Elaeis guineensis, is the source of palm oil – the ‘tropical golden oil’. Malaysia is the world’s largest exporter of this golden oil. Palm oil is a versatile oil with a wide range of uses in food and nonfood areas. Triglycerides constitute the major component of crude palm oil, with smaller proportions of diglycerides and monoglycerides. The oil also contains other minor constitu...

We assessed current water consumption during liquid fuel production, evaluating major steps of fuel lifecycle for five fuel pathways: bioethanol from corn, bioethanol from cellulosic feedstocks, gasoline from U.S. conventional crude obtained from onshore wells, gasoline from Saudi Arabian crude, and gasoline from Canadian oil sands. Our analysis revealed that the amount of irrigation water used...

Objective: To study changes in selected liver enzymes of albino rats fed on diet formulated with catfish that were exposed for 30 days to water polluted with crude oil. Methodology and results: One hundred and twenty (120) catfish (Clarias gariepinus) in six groups of 20 catfish each were held for 30 h in water having five different concentrations of crude oil (0.1, 0.25, 0.5, 0.75 and 1% v/v)....

We present a model for infrared radiance contrast of native and crude oil covered water surfaces. This model is based on the so called "direct" approach by treating individual volumetric elements as incoherent radiators. The total emitted radiation is calculated by the sum of individual contributions from the oil film and the underlying water, respectively. Therefore, different temperatures can...

Characterization of rheological behavior of alkali-surfactant-polymer (ASP) solution and oil emulsion is difficult, due to the complex chemical components and various physiochemical reactions with oil during chemical flooding. Through rheological experiments of ASP and crude oil emulsion, this paper presents the studies on influencing factors of rheological behavior, including interfacial tensi...

this study was designed to examine bioactive compounds of the thyme-enriched corn oil and to determine the antioxidant activity of its methanolic extract. volatile compounds composition was investigated by gas chromatography-mass spectrometry (gc-ms), whereas phenolic compounds analysis was performed by reversed-phase high-performance liquid chromatography (rp-hplc). antioxidant activities of t...

Millions of barrels of crude oil gushed freely from these wells, creating oil lakes in low-lying areas of the desert. Lakes were formed at more than 500 different locations, covering a total area initially estimated at 49 km. While the Kuwait Oil Company (KOC) has recovered 22.5 million barrels of the spilled crude; the remaining amount, is considered unrecoverable by standard methods. An estim...

The present paper describes the process optimization study for crude oil degradation which is a continuation of our earlier work on hydrocarbon degradation study of the isolate Stenotrophomonas rhizophila (PM-1) with GenBank accession number KX082814. Response Surface Methodology with Box-Behnken Design was used to optimize the process wherein temperature, pH, salinity, and inoculum size (at th...

The biodegradation of two crude oils by microorganisms from an anoxic aquifer previously contaminated by natural gas condensate was examined under methanogenic and sulfate-reducing conditions. Artificially weathered Alaska North Slope crude oil greatly stimulated both methanogenesis and sulfate reduction. Gas chromatographic analysis revealed the entire n-alkane fraction of this oil (C13-C34) w...

The Deepwater Horizon disaster released more than 636 million L of crude oil into the northern Gulf of Mexico. The spill oiled upper surface water spawning habitats for many commercially and ecologically important pelagic fish species. Consequently, the developing spawn (embryos and larvae) of tunas, swordfish, and other large predators were potentially exposed to crude oil-derived polycyclic a...
