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 = 10% Outlet BS&W =1% Solution: 1. Settling Equation. Investigate treating at 90°F, 100°F, 120°F. 2. … Continue reading

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% Outlet BS&W =1% Solution: 1. Settling Equation. Investigate treating at 80°F, 100°F, 120°F. 2. Retention … Continue reading

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), and treating temperature or fire-tube rating. As we have seen, these variables are interdependent, and … Continue reading

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 cut must be determined. As previously mentioned, it would be extremely rare to have laboratory … Continue reading

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 the laboratory but, in the absence of such data, 20 to 30 minutes is a … Continue reading

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. Since the oil continuous phase is flowing vertically upward in both vertical and horizontal treaters … Continue reading
