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.

The situation of low temperature crude oil pipeline carrying is universal. The rapid developing of pipe line supposes higher asking on new carrying technology. The problem of long distance carrying at normal temperature of high waxy crude oil is impel to resolve and its potential social economic profit is obvious. As the pipeline is designed at high production period of field so there must have low carrying situation at beginning and ending time. At the situation the high waxy crude oil and high pour point crude oil will face on great resistance and blockage problem. Further more the pipeline has to make great energy expense on high temperature carrying. So take new carrying technology to realize atmosphere temperature carrying is crucial of resolving low temperature carrying. The method of adding chemical pour point depressant(PPD)/flow improver additives (FIA) into crude oil directly was widely used at present. The progress of the additives and its study methods was summarized in the paper and supply some reference for the technology of PPD/FIA.
