NATCO ELECTRO-DYNAMIC DESALTER Electrostatic Desalting Technology

Enhanced multistage mixing in a single vessel

NATCO ELECTRO-DYNAMIC DESALTER electrostatic desalting technology for crude oil combines five technologies in a single, compact, reliable, and effective desalter:

  • NATCO DUAL POLARITY electrostatic treater 
  • NATCO LRC-II smart interface 
  • cocurrent and countercurrent washwater flow 
  • electrodynamic mixing 
  • composite electrodes.
NATCO ELECTRO-DYNAMIC DESALTER Electrostatic Desalting Technology

Advantages

  • AC/DC platform consistently outperforms traditional AC desalter technologies.
  • The technology can handle a wide range of inlet water contents and provides higher treating capacities at lower operating temperatures, reducing capex and opex.
  • Composite electrodes support a higher unit capacity and increased dehydration performance.
  • LRC-II interface improves emulsion resolution via voltage modulation, enabling operation at the optimal voltage for multiple crude feedstocks while managing upsets more rapidly and effectively.
  • Unique low-reactance power unit provides better power utilization with mixing voltages up to 60 kV.
