Wax deposition under low temperature conditions is a serious problem observed in pipelines transporting crude oil. Herein, three terpolymeric additives; styrene octadecyl acrylate maleic anhydride terpolymer, and the corresponding ester and imide were synthesized through the free radical polymerization technique for the first time. The above mentioned terpolymers were assessed as pour point depressors and paraffin inhibitors for Egyptian waxy crude oil with different concentrations ranging between 50 ppm and 200 ppm. The characteristics of the synthesized terpolymers were investigated using FTIR, 1 H-NMR, and GPC techniques. The FTIR and 1 H-NMR results demonstrated the successful synthesis of the mentioned terpolymers via confirming their structures. Also, the GPC results revealed the high average molecular weights of the ester and imide terpolymers compared to the corresponding terpolymer. Reasonable depression effects were achieved by the addition of lower concentrations of the synthesized terpolymers to the Egyptian waxy crude oil. The N-containing terpolymer; styrene octadecyl acrylate maleic anhydride imide, with a low concentration of 200 ppm exhibited the highest effect on the waxy crude as it was able to depress the pour point by 15 °C from the initial blank (27 °C to 12 °C), and a paraffin inhibition of 88 %. Thus, the synthesized terpolymers can be considered as promising and applicable additives for depressing the pour points and inhibiting the paraffinic precipitates for the waxy crude oil.

Fabrication of electrospun polyamide–weathered basalt nano-composite as a non-conventional membrane for basic and acid dye removal

et al. 2022

In this study, an adsorptive electrospun polyamide membrane (ESPA) and electrospun polyamide–weathered basalt composite membrane (ESPA-WB) were prepared by an electrospinning process at room temperature. Hence, the WB structure was built as a polymeric membrane separation film in combination with the ESPA matrix as a composite nano-filtration membrane. Then, the ESPA and ESPA-WB membranes were characterized using BET surface area analysis, Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy (SEM). To avoid cracks forming during the sintering process, the WB should be added in certain percentages. The microstructures of the prepared membranes were investigated to evaluate their efficiency for basic and acidic dyesʼ removal and their permeation flux. Compared with the ESPA, the ESPA-WB membrane combines the characteristics of WB and ESPA, which greatly enhances the performance of both methylene blue (MB) and methyl orange (MO) dyes removal from synthetic wastewater. The outcomes of this study indicated that the dye uptake in the case of ESPA-WB is higher than that of ESPA, and it decreases with an increase in dye concentrations. The obtained membrane ESPA-WB showed both an excellent anti-dye fouling and a good rejection property for both dyes (i.e. 90% rejection for MB and 74% for MO) with no sign of contamination by the applied dyes. It was found that the structure of the ESPA-WB membrane contains a large number of several adsorption sites which leads to an increase in the removal rate of dyes. Hence, this study demonstrated a non-conventional strategy to prepare an effective adsorptive nano-composite membrane that can be applied as a highly recyclable one for the removal of organic dyes.
