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...
متن کاملHow polymer additives reduce the pour point of hydrocarbon solvents containing wax crystals.
We have investigated how four different pour point depressant (PPD) polymers affect the pour point transition in mixtures of a single pure wax in a solvent. We used either n-eicosane (C20), CH3(CH2)18CH3, n-tetracosane (C24), CH3(CH2)22CH3 or n-hexatriacontane (C36), CH3(CH2)34CH3 as the wax component with either n-heptane or toluene as the solvent component. For all wax-solvent combinations, t...
متن کاملPetrophase 2014 Statistical analysis of crude oils and crude oil mixtures by LDI FTICR mass spectrometry
• Average mass list and logarithm scaling is preferred for PCA to separate oils in scoring plot. Fig. 1: a) Zoom-in of LDI spectra of three different crude oil samples. b) Zoom-in of LDI spectra of three repetitive measurements showing the good reproducibility of the measurement. Fig. 2: Class distribution plot of different crude oils detected as radical cations and protonated species [H] by LD...
متن کاملWhite Paper: An Automatic Test Method with Improved Precision for Wax Appearance Temperature (WAT) of Crude Oils
One such method, Differential Scanning Calorimetry (DSC), detects WAT by measuring the difference in heat absorbed or released between a reference sample and the test sample at a given cooling or warming rate. The WAT is detected by a deviation of experimental data from the reference baseline and typically requires a significant amount of wax formation for sensible detection. Consequently, it m...
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...
