Treating Equipment

Vertical or horizontal fired pressure vessels that apply heat to lower oil viscosity and surface tension, allowing emulsified water to coalesce and settle out as the oil moves through a settling section.

Treaters that apply a high-voltage AC or DC electric field across the emulsion to polarize and merge dispersed water droplets, achieving low BS&W with less heat — used as a heater-treater alternative on tight or heavy emulsions.

Vessels that remove the bulk of free (unemulsified) water by gravity settling ahead of the treater, reducing the thermal and chemical load on downstream treating equipment.

Atmospheric or low-pressure settling tanks in which oil rises through a water wash and gives long residence time for emulsion to break by gravity, common on lower-rate and stripper batteries.

Metering pumps and injection skids that dose emulsion-breaking chemicals into the production stream to accelerate water droplet coalescence and aid BS&W reduction.

Equipment that processes recovered slop oil and tank-bottom sludge — often using heat, chemicals, and settling or centrifugal separation — to reclaim salable oil and reduce waste volume.

Single vessels that integrate gas separation, free-water knockout, and emulsion treating, splitting the inlet stream into oil, water, and gas to consolidate the treating train into one unit.
