Research on Efficiency of Solvents of Paraffin Deposits
Abstract Differential scanning calorimetry has been used to study the phase transition of commercial paraffins in asphaltene-resin-paraffin deposits (ARPD). Paraffin deposits have been collected from the surface of oil field equipment in the Irelyakhskoye oil and gas field (Sakha Republic (Yakutia)....

| Summary: | Abstract Differential scanning calorimetry has been used to study the phase transition of commercial paraffins in asphaltene-resin-paraffin deposits (ARPD). Paraffin deposits have been collected from the surface of oil field equipment in the Irelyakhskoye oil and gas field (Sakha Republic (Yakutia). Gas condensate (GC) that is currently used in this field to remove deposits, as well as its mixture with cyclohexane and p-xylene, have been studied as ARPD solvents. The degree of crystallinity (DC) of paraffins has been identified to depend on the degree of aliphaticity of the mixed solvents used, with an increase in the degree of aliphaticity of the solvent, the DC of paraffins increases. Paraffins in the triple solvents are found to possess low DC and high melting points. The results of the research led to the conclusion that it is necessary to use GC with addition of aromatic concentrate to remove paraffin deposits in the oil field. |
