Rapid assessment of the paraffin composition of asphaltene-resin-paraffin deposits by thermal analysis and differential scanning calorimetry data
Abstract The unique integrated thermal analysis parameters F and P used by the authors for identification of crude oils [1] are proposed for determining the paraffin composition of asphaltene-resin-paraffin deposits. It has been shown that the parameter F, defined as the ratio of mass losses by asphaltene-resin-paraffin deposit in the temperature ranges of 20–400 and 400–700°C, characterizes the amount of hydrocarbon lube fractions and the parameter P, defined as the mass loss ratio in the temperature ranges of 400–510 and 510–700°C, characterizes the amount of the crystalline phase of paraffin hydrocarbons (according to differential scanning calorimetry data) and the amount of high-melting-point high-molecular-mass paraffins (according to component analysis data).
