“…The depressant pour point mixed into crude oil at 400 ppm is depicted in Figure 5. At temperatures above 55 • C, the viscosity of crude oil decreases and remains constant at subsequent temperatures [99], meaning that at this temperature, the crude oil flow benefits because it can flow without depressant pour points [100,101]. When the temperature decreases, the viscosity of crude oil increases, thereby increasing the viscosity of the oil, which is then accompanied by deposition [102,103].…”

Review of Solvents Based on Biomass for Mitigation of Wax Paraffin in Indonesian Oilfield

This paper presents a review of the expectations and challenges of using biomass in the prevention and slowing of paraffin wax deposition that takes place during the crude oil production process. The inhibition of the deposition process involves the use of solvents from biomass that are generally available around the crude oil production field. The processes used to scale down the precipitation of wax include mixing crude oil with the manufacturer's solvent composed of toluene and xylene. The goal is to assess solvents sourced from biomass that are capable to slow down the wax deposition process. Wax appearance temperature is an important characteristic to evaluate the possible wax precipitation of a given fluid. Wax precipitation can be reduced by using some chemical additives, often called the pour point depressant. This additive is expected to be produced from local biomass which can compete with solvents currently produced on the market.

“…In recent years, nanoparticle is selected to develop nanocomposite pour point depressant (NPPD) (AlSabagh et al 2016;Gao et al 2017;He et al 2016;Huang et al 2018Huang et al , 2019Norrman et al 2016;Song et al 2016;Tu et al 2018;Yang et al 2017;Yao et al 2018;Zhao et al 2018).

“…With the combination of NPPD and traditional PPD, the synergistic effect of magnetic field and PPDs has rarely been investigated. In the present work, the synergistic modification effect of an alternating magnetic field and a developed NPPD (He et al 2016;Huang et al 2018;Huang et al 2019) on waxy model oil is investigated. The yield stress of the waxy model oil is systematically characterized.…”

Yield stress, as the key parameter to characterize the network strength of waxy oil, is important to the petroleum pipeline safety. Reducing the yield stress of waxy oil is of great significance for flow assurance. In this study, the effect of alternating magnetic field (intensity, frequency) on the yield stress of a waxy model oil with nanocomposite pour point depressant (NPPD) is systematically investigated. An optimum magnetic field intensity and frequency is found for the reduction in yield stress. When adding with NPPD, the heterogeneous nucleation of NPPD contributes to the reduction in yield stress for waxy model oil. Interestingly, the magnetic field is helpful for the modification of yield stress at a lower frequency and intensity before the optimal value; however, the modification is found to be weakened when the magnetic field is further increased after the optimal value. Possible explanation is proposed that the aggregation morphology of wax crystal would be altered and results in the release of wrapped oil phase from the network structure under the magnetic field.
