Determination of Metal Ions in Crude Oils
Crude oil is complex mixture of hydrocarbons that occur in the earth in liquid form. It constitutes an important part of primary fossil fuels. Crude oil was used as a medicine by the ancient Egyptians, presumably as wound dressing, liniment and laxative. Several centuries later, Spanish explorers discovered crude oil in Cuba, Mexico, Boliva and Peru. The industrial revolution brought increasing...

The influence of different factors on the asphaltene stability in three iranian crude oils was evaluated. Compositional studies ...
متن کاملChemical composition, antimicrobial and antitumor activities of the essential oils and crude extracts of Euphorbia macrorrhiza.
The present study aimed to examine the chemical composition and biological activity of essential oils extracted from Euphorbia macrorrhiza collected from Northwest China. The major constituents of the essential oils of aerial parts and roots of E. macrorrhiza are acorenone B (16.72% and 25.80%), (+)-cycloisosativene (14.94% and 12.40%), 3a-hydroxy-5b-androstane (10.62% and 5.52%), copaene (7.37...
متن کاملInfluence of chemical composition on the fluorescence lifetimes of crude petroleum oils
Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the presence of a wide range of cyclic aromatic compounds, with the intensity and temporal behaviour of this fluorescence being directly related to chemical composition. In partic...
متن کاملFouling of Some Canadian Crude Oils
A thermal fouling study was undertaken using three sour Canadian crude oils. Experiments were carried out in a recirculation fouling loop, equipped with an annular (HTRI) electrically heated probe. Fluids at pressures of about 10001340 kPa under a nitrogen atmosphere were re-circulated at a velocity of 0.75 m/s for periods of 48 hours, and the decline in heat transfer coefficient followed under...
