Electrostatic Treaters / Heater Treaters

Electrostatic treaters help facilitate oil/water separation by breaking emulsions by applying electrical charges. An electrical grid installed in the coalescing section with electric current produces an electrical field in the coalescing section as electric current passes through the grid. Power is supplied to the grid through a transformer mounted on the vessel. Free water falls to the water section of the vessel and the emulsion rises to the coalescing section. As the emulsion passes through the electrical field the water droplets in the emulsion become electrically charged and they move about rapidly and collide with one another. As they collide the droplets grow forming larger droplets, until they become large enough to settle.

We provide both Dual Wave and Dual Polarity electrostatic treaters, these outperform mechanical electrostatic treaters in crude oil dehydration and desalting applications. The treater can be manufactured as a heater treater, providing heating and dehydration in a single vessel, and eliminating the need for externally heated heat transfer fluid. Our treaters handle a wider range of inlet water cut and provides higher treating capacities at lower operating temperatures, reducing cost.

Our engineered units include instruments, valves, and controls along with foundation design to suit client site requirements.
