An oil skimmer is a machine that removes floating oil and grease from liquid. Specifically, the floating oil adheres to skimming media, such as a belt, tube, rope, mop, or disk. Then, the media runs back to the machine to be wiped clean. Additionally, weir style skimmers use a pump to collect floating oils.
An oil skimmer is a mechanical device designed to remove floating oil from the surface of water or other liquids. Because oil is lighter than water, it rises to the surface — and that’s where skimmers do their job.
Whether in an industrial sump, a coolant tank, or an open body of water after a spill, oil skimmers help separate and recover this surface oil for reuse or disposal. Consequently, this process not only keeps systems clean but also prevents environmental contamination and regulatory violations.
Oil and water mixtures derived from manufacturing processes and food processing facilities that are held in large holding tanks or pits. In these applications, oil is usually removed by an oil skimmer or it can be pumped out for disposal. Skimming the floating oils with little water content can reduce the cost of disposal and lower the contingent liabilities of industrial wastewater discharge.
Oil Grabber Model MB Belt Oil Skimmer Application
The Abanaki Model MB Oil skimmer is a dependable and effective means of removing oil from water and water-base solutions. Often, oil skimming by itself will reduce oil to an acceptable level of water purity. Depending on the characteristics of the liquid, it is possible for the Model MB alone to reduce oil content to less than five parts per million in water. The unit can be used as a pretreatment before filtration, and in conjunction with a coalescing system. The Model MB oil skimmer utilizes continuous belts and wipers to remove up to 200 gallons of oil per hour from the fluid surface.
The belts, operating on a motor and pulley system, run through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belts pass through tandem wiper blades where oil is scraped off both sides of each belt and discharged. The tail pulleys have flanges which allow them to roll freely on the inside of the belts without becoming dislodged. These lower pulleys require no bearings and do not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulleys from being dislodged. Oil skimming makes use of the differences in specific gravity and surface tension between oil and water. These physical characteristics allow the belts to attract oil and other hydrocarbon liquids from the surface of the fluid. The Model MB Oil Skimmer can be used in tanks with depths as shallow as one foot or as deep as 100 feet.

Detecting Leaks and Removing Oil
New patent behind Abanaki Belt Oil Skimmer helps protect Catskill Mountain hydroelectric site.
The Blenheim-Gilboa Pumped Storage Power Project, which operates at the Mine Kill State Park in New York’s Catskill Mountains, relies on Abanaki’s Oil Grabber Model MB belt oil skimmer to detect leaks and remove oil from water sumps.
Upon demand, the Power Project can generate hydroelectric power quickly—up to 1,040,000 kw within just two minutes. Water is discharged into a lower reservoir adjacent to the 650-acre state park that was built by the New York Power Authority and is run by the Saratoga-Capital Region of the State Office of Parks, Recreation, and Historic Preservation.
The Project’s pumped storage is a closed cycle, with the same water used again and again. During periods of low power demand, the water is pumped back into the upper reservoir. No fossil or nuclear fuels are used, eliminating their related environmental considerations.
Because the power generation process uses large hydraulic systems to control water flow, it is conceivable that a failure in the hydraulic circuit could cause a hydraulic oil leak, which would result in an accumulation of hydraulic oil and water in a sump at the lower elevation of the plant. The Abanaki Oil Grabber Model MB provides a reliable and effective means for detecting the leak and removing oil from the water sumps.
The belt oil skimmer is mounted above the sump at a location that is frequented by operating personnel. If oil is present, it adheres to the belt in the sump and is removed from the belt at the higher elevation were it is observed. The source of the leaked oil is then located and repaired. The collected oil is removed for disposal, and clean water is discharged into the lower reservoir.
Recently, the U.S. Department of the Interior honored the New York Power Authority with its highest outdoor recreation award for the varied conservational, recreational, and cultural facilities developed by the Authority as part of the Blenhiem-Gilboa Power Project.
Abanaki Corporation is proud to count the Blenhiem-Gilboa Pumped Storage Power Project among its customers. Headquartered in Cleveland, Ohio, Abanaki is the world leader in belt oil skimmer solutions for virtually any application. For more than 30 years, the company has served a global customer base in industries as diverse as iron and steel, wastewater, paper, food processing, automotive, environmental remediation, and recycling.
