In this environment, oil and gas companies are seeking opportunities to improve processes and technologies to remain competitive. Upstream oil and gas companies need integrated views of their production processes all the way from the reservoir to the pipeline. They must optimize their processes and perform predictive analysis of production problems to minimize losses. In downstream operations, ...

The refining industry is currently undergoing its most serious challenge in recent times, since cleaner fuels are gradually introduced in many markets. Middle East countries still have less history than Europe, Japan or the USA when it comes to clean fuels, but the trend is there, which will eventually increase the demand for hydroprocessing catalysts. On the other hand, more sophisticated cata...

the oil-paper insulation is a type of an inexpensive combination insulation system in oil-filled power transformers. in this study the dielectric and strength properties of canola oil and mineral oil impregnated hand-sheet papers were investigated. all hand sheets were made of unbleached bagasse soda pulp with two different freeness levels of 200 ± 25 ml, csf and 400± 25 ml,csf. after drying th...

With the demand for gasoline and diesel expected to decline in near future, crude-to-chemicals technologies have potential become most important processes petrochemical industry. This trend has triggered intense research maximize production of light olefins aromatics at expense fuels, which calls disruptive able transform crude oil chemicals an efficient environmentally friendly way. Here we pr...

nanotechnology has the potential to introduce revolutionary changes to several areas of oil and gasindustry such as exploration, production, enhanced oil recovery, and refining. in this paper, the effectof different concentrations of fe2o3 nanoparticles as a catalyst on the heavy oil viscosity at varioustemperatures is studied. furthermore, the effect of a mixture of fe2o3 nanoparticles and ste...

The etiologic agent(s) that was responsible for the 1981 toxic oil syndrome [TOS] epidemic in Spain has not been identified. Liquid chromatography combined with atmospheric pressure ionization tandem mass spectrometry was used for the analysis of oils associated with TOS. Analyses focused on measuring 3-(N-phenylamino)-1,2-propanediol [PAP], the 3-oleyl ester of PAP [MEPAP], and the 1,2-di-oley...

Rice bran oil is unique among edible oil due to its rich source of commercially and nutritionally important phytoceuticals such as, oryzanol, lecithin, tocopherols, and tocotrinols. However, most of these phytoceuticals are removed from the rice bran oil as waste byproducts during the refining process. γ-oryzanol is one of such component having the potential to be used in nutraceutical, pharmac...

Hydrothermal liquefaction (HTL) of Litsea cubeba seed was conducted over different temperature (250-350°C), time (30-120 min), reactor loading (0.5-4.5 g) and Na2CO3 loading (0-10 wt.%). Temperature was the most influential factor affecting the yields of product fractions. The highest bio-oil yield of 56.9 wt.% was achieved at 290°C, 60 min, and reactor loading of 2.5 g. The presence of Na2CO3 ...

A recoverable catalyst that simultaneously stabilizes emulsions would be highly advantageous in streamlining processes such as biomass refining, in which the immiscibility and thermal instability of crude products greatly complicates purification procedures. Here, we report a family of solid catalysts that can stabilize water-oil emulsions and catalyze reactions at the liquid/liquid interface. ...

Cavitation, as a unique technology for influencing liquid substances, has attracted much attention in the oil refining industry. The capabilities of cavitation impact can initiate destruction molecular compounds liquid. At same time with large number successful experimental studies on treatment hydrocarbon raw materials, not been introduced Often impossibility implementation is based lack unifi...
