VERTIFLOAT™ 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 (<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
