A heater treater is a 3-phase separator vessel that utilizes heat and mechanical separation devices to facilitate the separation of oil-water emulsions before transporting the dry oil through pipelines.
Horizontal Heater Treater
The orientation of a horizontal heater treater is a cylindrical vessel lying on its side. Horizontal heater treaters have the same basic operation as vertical treaters but have a larger section for treating the crude.
A key benefit of this orientation is that the vessel can handle higher volumes of fluid and heavier crudes that require longer retention periods for separation. Horizontal heater treaters can treat emulsions of any API gravity with high water content.
Vertical Heater Treater
Vertical heater treaters are cylindrical vessels in an upright position. They have a smaller crude treating volume than the horizontal type, making them ideal for space-constrained applications. These vessels are better suited for separating lighter crudes that require shorter retention periods. Vertical heater treaters can treat emulsions having API gravity up to 27 and low water content.

Untreated crude enters the degassing section via an inlet located at the top of the vessel and dry, associated gases are vented into a gas collection line containing a mist extractor. Produced water within the crude drops to the bottom of the vessel and is tapped off from a separate outlet. The emulsion passes into a heating section containing fire tubes that heat it indirectly with heated water. This ‘washes’ the crude mixture, separating the free water and solids.
The treating temperature typically used can be anywhere from 98.6 – 158 °F depending on the crude viscosity. The purpose of heating the oil is to reduce its viscosity and aid the breaking of the emulsion. The oil and emulsion rise over the fire tubes and flow into an oil surge chamber containing a differential float device that regulates the oil level. Some heater treaters have a section containing a filtering medium to screen solid particles out of the oil.
The oil and emulsion flow into the coalescing section through a spreader. This section comprises an electrostatic device that passes alternating current through the emulsion to induce droplet coalescence. As the water molecules separate from the emulsion, they collide and form larger droplets that settle to the bottom of the tank under the force of gravity. The dry oil is tapped via a separate outlet at the top of the tank.
A heater treater consists of four sections that perform the following functions:
- Degassing
- Heating
- Differential oil control
- Coalescing
