Vertical Heater Treater

The Vertical Heater Treater breaks emulsions in crude oil using heat and retention time.

The Vertical Heater Treater efficiently helps remove water and emulsion from crude oil wellstreams, so you can keep your production flowing. Once the oil emerges from the treatment process, it is ready for further processing or pipeline delivery.

Key Benefits

  • Expedited production drawings available as early as 4-5 business days for faster planning
  • Single well or multi well designs available along with full pad well designs
  • Robust skid design and commitment to service help bring operations online quickly
  • Cost-effective maintenance
  • Installation and commissioning of the units to facilitate and speed startup
  • Industry-leading delivery to speed startup

How it Works

The well stream first enters the emulsion inlet near the top of the unit and is diverted against the treater shell. Gas separates from the liquids, ascends and exits the unit. Warm vapor from the lower section flows up to the gas separation section and mixes with the cool inlet stream. Heavier components in the gas condense and descend. The oil, water, and emulsion liquids that descend are collected beneath the firebox. Free water separates from the oil and discharges from the bottom section through the adjustable external siphon.

The spreader breaks up the remaining oil and emulsion and the remaining water is discharged with the free water. Treated oil flows through the heat-retaining baffle above the firetube, exits through the oil outlet at the top of the settling section, and is conveyed to a storage tank.
