the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...

in today’s turbulent world, the continuity of criticalactivities in the event of disruptions, and also fast recovery and return tobusiness as usual, are vital for sustainable success of companies. maintainingcontinuous delivery of critical business processes in the event of disruptions isa matter of business continuity. business continuity management system (bcms)is concerned with the developme...

an important property that has been extensively studied in quantitative structure activityrelationship (qsar) is the chromatographic retention index. qsar study is suggested for theprediction of retention index of alkanes and alkenes compounds. modeling of the retention indexof alkanes and alkenes compounds as a function of molecular structures was established bydifferent chemometrics methods. ...

Near-infrared (NIR) spectroscopy has been successfully utilized for the rapid identification of six typical petroleum products such as light straight-run (LSR), naphtha, kerosine, light gas oil (LGO), gasoline, and diesel. The spectral features of each product were reasonably differentiated in the NIR region, and the spectral differences provided enough qualitative spectral information for disc...

High-temperature gas chromatography (HTGC) has enhanced our ability to characterize hydrocarbons extending to C120 in crude oils. As a result, hydrocarbons in waxes (> C20) have been observed to vary signi®cantly between crude oils, even those presumed to originate from the same source. Prior to this development, microcrystalline waxes containing hydrocarbons above C40 were not characterized on...

Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a global tourist destination. The present work aims at identifying the source oil of the tar balls that consistently depositing along the Goa coast using multi-marker fingerprint ...

Seven crude oil samples recovered from wells of El Hamd and Bakr oil Fields locates in Egyptian central Gulf of Suez were subjected for Description, bulk composition of Maltene Fraction and hydrocarbons distribution. The Comparison of collected crude oils was achieved using Bulk parameters and Specific parameters, the first ones refer to properties of the whole sample such as API gravity, sulfu...

The most usual type of petroleum mulch, which has been successfully used to combat desertification in large areain Iran for more than thirty years, is produced by heavy residue petroleum cuts. The petroleum mulch consists of awide range of different heavy hydrocarbons such as Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are present atlow level in petroleum mulch, where there is contact with wa...
