Overview

Experimental study demonstrates effective crude oil demulsification by magnetic dendron nanohybrids, indicating a sustainable route for petroleum transport.

Key Points

  • Synthesize a novel superparamagnetic Fe3O4 nanohybrid functionalized with a polyester bis-MPA dendron (PEDHA-Fe3O4) and evaluate its capability to break stable water-in-crude oil emulsions.
  • Synthesized PEDHA-Fe3O4 nanohybrids via covalent functionalization of magnetite nanoparticles with polyester bis-MPA dendron, 2-hydroxyl, 1-azide dendrimer.
  • Characterized nanohybrid structural and magnetic properties using vibrating sample magnetometry, attenuated total reflectance (ATR)-FTIR, and quantum chemical modeling.
  • Evaluated demulsification kinetics, interfacial tension (IFT) reduction, and emulsion stability using cross-polarized microscopy and differential light scanning (Turbiscan) against commercial DTG-62.
  • PEDHA-Fe3O4 exhibited superparamagnetic behavior with saturation magnetization values of 63.913 emu/g (25 mg loading) and 33.559 emu/g (50 mg loading).
  • At a 15 mg/L dosage, the nanohybrid achieved 71.2% emulsion-breaking efficiency and reduced oil-water interfacial tension from 2.67 mN/m to 0.77 mN/m.
  • Water removal reached ~78.13% after 50 hours with PEDHA-Fe3O4, significantly exceeding the ~2.02% water removal observed for the commercial demulsifier DTG-62.
