Vertifloat™ Vertical Flotation Unit

Compact and reliable, our VertiFloat® purifies wastewater using 2-stages of oil droplet coalescence along with a single flotation-compartment conserving precious deck space and weight.

VERTIFLOAT™ VERTICAL 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:

One-cell IGF: 50-90%

Four-cell IGF: 70-98%

Inlet contaminant concentration:

One-cell IGF: 200 mg/l, max (<100 mg/l preferred)

Four-cell IGF: 500 mg/l, max (<300 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 (0.5 m/min.)
  • 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
