Implication

This work evaluates a new copolymer as a flow modifier for low waxy crude, highlighting significant improvements in flow properties.

Key Points

  • The research aims to synthesize and evaluate poly(EMA‐co‐VA) as a flow modifier for low waxy crude oil.
  • Synthesis of poly(EMA‐co‐VA) via free radical polymerization
  • Analysis of molecular weight and polydispersity index using Size Exclusion Chromatography (SEC)
  • Rheological and morphological studies on waxy crude oil with varying copolymer concentrations
  • Poly(EMA‐co‐VA) reduced the gelation point of crude oil from 15.1 °C to 3.6 °C at a concentration of 2000 ppm
  • Maximum viscosity reduction of 87.3% at 0°C with the addition of poly(EMA‐co‐VA) at 3000 ppm
  • The copolymer significantly interacts with paraffinic wax crystals, reducing their size and inhibiting growth.
