The Brass Canal site is a tank farm on Brass Island, with a canal and drainage area where oily water has to be intercepted and the oil recovered. The oil on site was a light crude (API gravity 37.6, density 0.8364 kg/L at 15 C, kinematic viscosity 3.7 mm2/s at 20 C). Light, low-viscosity oils run through ordinary sorbents and are hard to hold. The operator needed field evidence, under real conditions and at 30 C outside temperature, that a reusable sorbent keeps the oil and leaves the water.
Field validation of FoamFlex200 on Nigerian Brass Light Crude in a canal and drainage area.
The team mapped the canal and drainage layout from the air and chose where to place the material.
FoamFlex200 carpets (4 standard and 1 half carpet) were placed on the oil, left to work, then lifted out in sequence.
Saturated carpets were wrung out to recover the oil in containers, and filters were installed in the drainage area.
The five carpets retained 45.84 L of Nigerian Brass Light Crude and 0 L of water.
Official lab results gave a hydrophobic effect above 96.25% and an oleophilic effect above 99.1%. FoamFlex200 can be reused up to 200 times with performance retained above 93%.
Because the oil has a viscosity below 15 mm2/s, the result is expressed as hydrocarbon retention rather than absorption. The validation recommended FoamFlex200 for operational use.
FoamFlex200 standard carpet (FF200), 4 pieces, and FoamFlex200 half carpet (FF200 half), 1 piece.
Reusable absorbent carpet with velcro and handles, ideal for all types of spills and compatible with FF-WRING.
45.84 L of Nigerian Brass Light Crude with 4 FF200 standard carpets and 1 half carpet, and 0 L of water picked up.
Yes. The test used a crude with API gravity 37.6 and viscosity 3.7 mm2/s at 20 C. Below 15 mm2/s the performance is reported as hydrocarbon retention.
Up to 200 times, with performance retained above 93%. Saturated carpets are wrung out and put back to work.
