The weir skimmer is designed to recover oil spill, oil, and oil emulsions with medium to high viscosity with a range of 70 – 350 m3/h from a floating oil on the water under calm to rough weather conditions. The weir skimmer selectively recovers oil over the top of the central weir sited just below the slick’s upper surface by gravity’s force into a primary reservoir where it is pumped to storage. The Weir Oil Skimmer system consists of a pump + floating system + powerpack + hose reel + remote control.
With a self-adjustable weir, the forward motion of the skimming system provides the flow into the skimmer. Depending on the weir opening’s size, the skimmer will accept most of what it encounters, allowing it to handle highly viscous oils. Advancing Weir Skimmer typically recovers large volumes of water; oil/water separation should be considered to increase overall efficiency. The weir skimmer creates a current that induces the weir’s oil flow, and this concentrating effect increases recovery efficiency.
The Weir Oil Skimmer system is usually all hydraulically operated; optional diesel, gas, or electric hydraulic power packs, pneumatic or electric power, and manual or remote operation are possible. With the Continuous self-floating umbilical and thruster system, Weir Oil Skimmer gets the motion capability up to 150 meters.
The pump can be integrated or external for Weir Skimmer, removed from the skimmer, and used as a tanker offloading pump.
The integrated centrifugal screw pump does not require priming, handles viscous oil, is tolerant of most debris types, and does not form oil/water emulsions.
An external pump can be installed on the weir skimmer. The skimming head of the weir skimmer is typically tiny and maneuverable, allowing its use in confined spaces such as among dock pilings.
The skimmer handles all oil types, from light diesel fuel to heavy crude oil mixed with debris. The protection screen secures the skimmer, and also, Special cutting knives are fitted in both the inlet and outlet end of the pump.
Weir Oil Skimmer – Oil Skimming Applications divided into three groups;
- Offshore Oil Skimming
High capacity floating oil skimmer that skims and separates oil from Open sea and offshore
- Inland Waters + Coastal Waters Oil Skimming
High or low capacity floating oil skimmer that skims and separates oil from inland waters and coastal water
- Industrial Oil Skimming
High or low capacity floating oil skimmer that skims and separates within various industrial settings ranging from manufacturing and processing activities to wastewater management in hazardous and corrosive environments such as
(Wastewater + Food processing + Refineries + Steel Mills – Scale pits + Vegetable Oil Processing Plant+ Chemical Plant + Oil Processing)
