NATCO DUAL POLARITY Electrostatic Treater

More efficient dehydration and desalting with a larger operating range at lower operating temperatures

The NATCO DUAL POLARITY electrostatic treater outperforms both mechanical and AC electrostatic treaters in crude oil dehydration and desalting applications in upstream and downstream operations.

The treater can be delivered as a heater treater, providing heating and dehydration in a single vessel and eliminating the need for externally heated heat transfer fluid.

NATCO DUAL POLARITY Electrostatic Treater

Cost-effective treatment

The NATCO DUAL POLARITY treater handles a wider range of inlet water cut and provides higher treating capacities at lower operating temperatures, reducing capex and opex. 

The treater requires less washwater than an AC desalter as a result of the improved mixing from electrophoretic movement of the water droplets in the electrostatic field.

Improved performance

The optional load-responsive controller—the NATCO LRC-II smart interface—enhances emulsion resolution via voltage modulation, enabling operation at the optimal voltage for multiple crude feedstocks while managing upsets more rapidly and effectively.

The Hi-Flo distributor improves vessel hydraulics and enhances performance to support higher throughput.
