# Example Sizing a Vertical Treater

Given: Oil gravity = 40°API, 0.875 S.G. Oil flow rate = 2,000 bpd Inlet oil temperature = 90°F Water S.G. = 1.04 Inlet BS&W =…

# Example Sizing a Horizontal Treater

Given: Oil gravity = 30°API, 0.875 S.G. Oil flow rate = 5,000 bpd Inlet oil temperature = 80°F Water S.G. = 1.04 Inlet BS&W =10%…

# Treaters Design Procedure

In specifying the size of a treater, it is necessary to determine the  diameter (d), length or height of the coalescing section (Leff or h),…

# Treaters Water Droplet Size

In order to develop a treater design procedure, the water droplet size to be used in the settling equation to achieve a given outlet water…

# Treater Retention Time Equations

The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…

# Treater Settling Equations

The specific gravity difference between the dispersed water droplets and the oil should result in the water “sinking” to the bottom of the treatment vessel.…

# Electrostatic Treaters

Some treaters use an electrode section. Figure 6-11 illustrates a typical design of a horizontal electrostatic treater. The flow path in an electrostatic treater is…

# Horizontal Treaters

For most multi-well situations horizontal treaters are normally required. Figure 6-10 shows a typical design of a horizontal treater. Flow enters the front section of…

# Vertical Treaters

The most commonly used single-well lease treater is the vertical treater as shown in Figure 6-8. Flow enters the top of the treater into a…

# Electrostatic Coalescers

Coalescing of the small water drops dispersed in the crude can be accomplished by subjecting the water-in-oil emulsion to a high-voltage electrical field. When a…
