VertiFloat - Model CFU -Compact Flotation Unit

Flotation Devices are Used as a Final Polishing Stage

Flotation devices are designed to remove (or polish) the most difficult contaminants from the produced water – small droplets of oil and small, oil-coated solids. Therefore, flotation equipment is subject to the following general limitations:

Percent removal of contaminants:

• Single-cell IGF: 50-90%

Inlet contaminant concentration:

• Single-cell IGF: 200 mg/l, max (less than 100 mg/l preferred)

Key Features of Vertifloat Design

• Compact, efficient, reliable
• Designed primarily for floating platforms or fixed platforms with limited deck space
Lowest downward fluid velocity )
• Process 30% over design flow rate
• Produced Water Inlet releases gas slugs avoiding upsets in the oil pad
• Distributes water evenly over the vessel`s cross section Triple stage oil droplet coalescence
• Precoalesces oil in water inlet through centrifugal force
• ESI Matrix™ coalescing media installed for second stage separation
• Specially designed effluent nozzle prevents fluid short-circuiting
• Standard chemical injection system efficiently disperses high MW flotation polymers
