In the aura of this research we developed the grafted nanocomposite pour point depressant by culmination of a set of monomers namely acrylamide, maleic anhydride, styrene, and octadecyl methacrylate and further grafted to nano silica for improving the flow properties and thereby decrease the temperature of pour point value of the NorthEast Indian waxy based crude oil. Moreover, to emphasize and understand the central effects of different concentrations of synthesized nanocomposite pour point depressants on the pour point of waxy crude oil, several important experiments were undergone and later its results were compared with the commercial pour point depressant. In addition, the rheological props of the sample crude were also analyzed with and without additives. The results shows that the synthesized nanocomposite has more effectively reduced the viscosity as well as pour point of the sample to desired value when compared to that of the commercially used pour point depressant.

Maleic Anhydride Copolymer

The amidation grafted copolymers derived from styrene-maleic anhydride copolymer were prepared and characterized by FTIR. Their intrinsic viscosity and crystal morphology were measured. The prepared polymers were investigated as pour point depressants (PPD) and flow improvers for waxy crude oil, and it was found that the depression effect of PPD modified by mixture amines was more effective than single amine, and the maximum depression was obtained by the sample that modified by mixture amines from 13 °C to 4 °C (ΔPP = 9 °C, at 3 000 ppm). The effect of the PPD modified by mixture amines on the flow properties of waxy crude oil was investigated. The result show that the viscosity decreased from 1 223 mPa.s to 81.3 mPa.s at 13 °C and 3 000 ppm. In addition, the crystal morphology have also been improved for the same sample and conditions.
