Determination of concentrations of sulfur compounds in different petroleum samples is a true analytical challenge. Only analytical procedures based on gas chromatography can meet the sensitivity and accuracy requirements dictated by up-to-date petroleum industry. The objective of this work is to develop the method for the quantifying of sulfur compounds in petroleum hydrocarbon streams. The opt...

Genotoxic responses towards chronic exposure of Chaetoceros tenuissimus and Skeletonema costatum to water accommodated fraction of petroleum hydrocarbons (WAF-P) were evaluated as biomarkers of petroleum hydrocarbons pollution. The DNA damage caused by water accommodated fraction of petroleum hydrocarbons was assessed in terms of the DNA integrity measured by alkaline unwinding assay. The compa...

The wastewater from petroleum industries contains high organic matter content, oil and grease, dissolved solids and turbidity. The petroleum wastewater normally treated in a plant comprising of primary, secondary and tertiary treatments. The high organic loading needs to be treated in biological treatment step. Biological treatment can be suspended growth or attached growth type. Activated slud...

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...

UNLABELLED BACKGROUND Petroleum pollution is a global disaster and there are several soil cleaning methods including bioremediation. METHODS In a field study, fugal strains were isolated from oil-contaminated sites of Arak refinery (Iran) and their growth ability was checked in potato dextrose agar (PDA) media containing 0-10% v/v crude oil, the activity of three enzymes (Catalase, Peroxid...

Major degraders of petroleum hydrocarbons in tropical seas have been indicated only by laboratory culturing and never through observing the bacterial community structure in actual environments. To demonstrate the major degraders of petroleum hydrocarbons spilt in actual tropical seas, indigenous bacterial community in seawater at Sentosa (close to a port) and East Coast Park (far from a port) i...

BACKGROUND Hydrocarbons which are among the major components of petroleum products are considered toxic and have been implicated in a number of human diseases. Tanker drivers are continuously exposed to hydrocarbons by inhalation and most of these drivers do not use protective devices to prevent inhalation of petroleum products; nor do they visit hospital regularly for routine check-up. OBJEC...

Artificial neural networks are rapidly gaining popularity. This paper discusses the importance of this new tool to petroleum engineers, and the advantages that this computing process has over other conventional methods. The mechanics by which neural networks achieve their objective are also discussed. Artificial neural networks can assist petroleum engineers in solving some fundamental petroleu...

Although mass spectrometry has been studied extensively in the past 50 years for analysis of petroleum and other fossil fuels, comprehensive characterization of total petroleum composition across a wide boiling range remains a challenge. In this work, we report our efforts in combining GC separation, field Ionization, and time-of-flight high-resolution mass spectrometry (GC-FI-TOF HRMS) for det...
