- Abstract
The aim of the current study is to synthesize a terpolymer of (Nafol 1822C acrylate-co-maleic anhydride -co-Hexadecyl methacrylate (NA-co-MA-co-HDM) to improve the pour point of crude oil. The structures of the Nafol 1822C acrylate and hexadecyl methacrylate monomers were confirmed by FTIR spectra. The effect of polymerization parameters, such as reaction temperature, initiator concentration, experimental duration, and monomer concentration on the yield of the synthesized terpolymer was evaluated as pour point depressant for crude oil. The experimental results showed that the optimum conditions to obtain the highest yield were at the reaction time of 8 hours, initiator concentration of 1wt%, reaction temperature of 90oC, and monomers ratio of (NA: MA: HDM) 2:1:1. The efficiency pour point depepressan for crude oil was increased by increasing the concentration of terpolymer. Rheological properties of crude oil (with and without additives) were studied. Comparison of structures of wax crystals in untreated and treated crude oil was also done by photo micrographic analysis.
