Overview

Demonstrates the effectiveness of EVA/SiO2 in enhancing crude oil flow properties, suggesting a promising solution for waxy oils.

Key Points

  • The research aims to evaluate the effectiveness of an EVA/SiO2 nanocomposite as a pour point depressant for Indian waxy crude oil.
  • Synthesis of EVA/SiO2 nanocomposite
  • Characterization using FTIR, TGA, FE-SEM, and HR-TEM
  • Evaluation through pour point measurement and rheological analysis
  • Testing in aging studies and pipe flow loop testing
  • EVA/SiO2 lowered the pour point by 17 °C
  • Reduced viscosity by 83.9% at 25 °C and 97.5% at 40 °C
  • Wax appearance temperature decreased from 62 °C to 32 °C
  • Gelation temperature reduced from 52 °C to 24 °C
  • Demonstrated an 88% reduction in pressure drop gradient at 40 °C
