Scanning calorimetry and thermogravimetry in analysis of petroleum systems. Determination of the component composition

The possibility of qualitative analysis of heavy hydrocarbon mixtures by differential scanning calorimetry (DSC) and quantitative analysis combined with thermogravimetry (TG) was demonstrated. In experimental conditions that ensure complete oxidation of the sample on heating, successive oxidation and evaporation of paraffins, light and heavy aromatics, and naphthenes, resins, ...

Synergism of depressants in petroleum systems

Systems of the coking gasoil type with residual and distillate cracking residues were investigated by electrophysical methods. Electrical processes, in particular, electrostatic blocking of high-melting components and formation of asphalt-resin complexes on electrically active centers, as well as mechanical factors, are responsible for the synergism and depressant activity. At ...

Rheological properties of crude oils with a high resin and asphaltene content. Effect of an electromagnetic field and modifiers

The rheological properties of crude oils from the Kuchukov field were investigated at 20–70°C in the presence of surfactants and after treatment with a high-frequency electromagnetic field. The viscosity of crude from one field is a function of the resin and asphaltene content. Addition of ethylene glycol diglycidyl ether improves the rheological characteristics.
