“…The rheological tests of untreated crude oil were performed using a Bohlin Gemini II rheometer (Malvern Instruments, UK) at temperatures of 10, 20, 30, and 40 °C. The wax content of the crude oil was determined with the method Modified Universal Oil Products (UOP) 46-64 using solvents n -pentane and acetone, where hexane was used as a washing solvent. ,,− The amount of saturates, aromatics, resins, and asphaltenes (SARA) present in the crude oil were determined using a column chromatography method as per the experimental procedures outlined by Deka et al and others. ,,, The WAT of the crude oil was calculated from rheology according to the deviation observed in the Arrhenius relation between the viscosity of the crude oil sample and temperature. , Further characterization details of crude oil are mentioned in the Supporting Information (section 1).…”

In this research article, novel polymer nanocomposites poly(2-ethylhexyl acrylate)–graphene oxide [P(2-EHA)–GO] were developed (with 0.5–2 wt % GO concentrations) by in situ free-radical polymerization and were characterized using several analytical techniques to confirm the formation of nanocomposites. Subsequently, when doped in crude oil, beneficiation was observed in pour point and rheological parameters of a selected waxy crude oil, thus evaluating them as potential pour point depressants (PPDs). An optimized amount of GO (1 wt %) in nanocomposite results in improved flow characteristics of crude oil, providing a notable 18 °C depression in the pour point and upto 99% reduction in its apparent viscosity (down to 0.01 Pa s). Comparison of its beneficiation effect with P(2-EHA), the base polymeric PPD, indicated a superior performance using nanocomposite PPDs which was mainly attributed to a proposed pour point depression mechanism, according to which the GO sheets act as nucleation sites upon which wax crystal precipitates, helping polymeric chains to cocrystallize with these wax molecules and thereby avoiding the formation of a wax interlocking network. Additionally, the nanocomposite PPDs improved the restart flowability of crude oil, causing upto a substantial 17.8 °C reduction in its gelation point. Moreover, they exhibited better control over the aging effect in crude oils than P(2-EHA) and even better than the previously synthesized nanocomposite poly(methyl methacrylate)–GO upto 15 and 30 days. Overall, this study provides new insights into the physical nature of graphene–wax interactions and illustrates the resultant wax morphology modifications, which would help in the development and application of numerous graphene-based products for the flow assurance community of the researchers and the petroleum industry.

“…К числу присадок, наиболее часто используемых для улучшения текучести парафинистых масел при низких температурах, относятся сополимеры этилена и винилацетата (ЭВА), которые состоят из углеводородной цепи (аполярной) и полярных группировок. Асфальтены снижают температуру застывания, и этот эффект увеличивается с увеличением концентрации асфальтенов, указывая на то, что асфальтены взаимодействуют с парафинами, образуя частицы с другим профилем взаимодействия [51].…”
