Structure–Solubility Relationship of CO Dispersion in Model Hydrocarbon Liquids and Heavy Oil Fractions

In order to change the viscosity of high-resinous oil of the “Karazhanbas” field (Kazakhstan), the effect of electrohydraulic action on it was studied. The effect of adding an organic solvent xylene on the rheological properties of oil is investigated. A comparative study of the hydrocarbon composition of oil before and after electrohydraulic impact was carried out by the method of gas chromatographymass spectrometry. Fragment composition of oil hydrocarbons before and after electrohydraulic treatment was determined by 1H and 13C NMR spectroscopy. It is shown that the conversion of heavy oil fractions to light ones begins with a five-time electrohydraulic impact. It is determined that 20‒25 electric discharge pulses are sufficient for the quantitative process of splitting hydrocarbons. It was found that the addition of xylene to high-viscosity oil leads to an increase in the conversion of hydrocarbons under electrohydraulic action. The content of paraffins and naphthalenes in high-viscosity oil is slightly reduced during electrohydraulic processing. In oil, after electrohydraulic action, a decrease in the proportion of protons of long alkyl terminal СН3-groups of hydrocarbons is observed, which indicates the process of decomposition of heavy oil fractions into light fractions.

Identification and assessment of phenol and phenolic rich components of heavy oil fractions of biomass pyrolytic oil were conducted. The original bio-oil used for this study was derived from the pyrolysis of empty fruit bunch (EFB). It was separated into water soluble (light oil) and water insoluble (heavy oil) components by mixing it with water at 2:1 V/V ratio under ambient condition with vigorous stirring using centrifuge for 30mins. The raw bio-oil and the heavy oil fractions were later characterized using Fourier Transform Infra-Red (FTIR) and Gas chromatography-Mass spectroscopy (GC-MS) techniques in order to identify the function groups present and their compositions. The GC-MS results for the heavy oil indicated a high concentration of phenol and phenolic components, which was strongly supported by the presence of OH group (characteristic of phenol) from FTIR analysis. Utilization of bio-oil which was known to have a significant amount of phenol and phenolic rich components for phenolic, novolac or epoxy resin manufacture would significantly reduce the cost and negative environmental effects of the fossil-based resins.

The Relationship

The desanding in heavy oil has been indispensable to oilfield exploration and production. The methodology of natural sedimentation is considered the effective way in oilfield, as a consequence of the best separation effect, a large handling capacity, low energy consumption, simple operation and low-carbon green. This paper did some research on natural sedimentation separation characteristics in the desanding of heavy oil, through experimental study, in order to test setting time and viscosity of various kinds of size in heavy oil, which indicates the relationship of viscosity, size and sedimentation rate. Not only make sure the relationship of setting time, viscosity and size, but also the boundary between floating zone and stable region in the desanding of heavy oil, Based on these data which has an important guiding role to make sure the time that natural sedimentation takes for oil-water-sand, desanding properties of heavy oil and separator size.
