Electrostatic Coalescers: Desalting and Dehydration of Crudes


Crude Oils Desalting.

Salt contents in crudes depend on residual water droplets after primary separation

  • Injection and emulsification of dilution water
  • Electrostatic coalescence of the emulsified droplets
  • Settling of larger drops
