Tube oil skimmer is a surface tube oil skimmer that can effectively removes floating surface oils by means of an oleophilic (oil attracting) 3/4 inch diameter continuous looped tube. The tube extends out over the surface of the tank or pit and collects the free floating oils.

Abanaki tube oil skimmer (The Oil Viper) has a specially designed method for removing the oil from the tube. It has a unique wiper combination attached to the tube itself in addition to the ceramic wiper on the skimmer. The result is a virtually oil free tube as it leaves the surface oil skimmer for quicker oil removal. Removal rates can be as high as one hundred gallons per hour.

How Does a Tube Oil Skimmer Work?

The Oil Viper tube oil skimmer can be used in wastewater applications that are shallow in depth. The Oil Viper tube oil skimmer is a great fit where a belt skimmer is too big. Due to the sleek design of the Oil Viper tube oil skimmer it can skim in just inches of water compared to a belt skimmer which could need one to two feet of water to skim from.

The Oil Viper tube oil skimmer works off the same principle of the belt skimmer, the tube breaks the surface tension of the water, the oil is then collected and skimmed off by its unique wipe clean design. Two tube materials are available, the standard tube is great in a wide variety of applications; the high temperature tube is best suited for high temperature or caustic applications.

Large Tube Oil Skimmer  

Large tube skimmers use a floating plastic hose that snakes out over the surface of the liquid and is then drawn back through the drive unit where oil is removed. This design requires a relatively large amount of fluid surface area for proper operation. Length considerations are the same as for belt skimmers; a typical tube diameter is 1 inch.

Small Tube Oil Skimmer

Mini tube skimmers are very similar to the larger tube units, but typically have either a 3/16-inch or a 5/16-inch diameter tube. The 5/16-inch diameter is preferable as it has enough stiffness to not drag on the housing and prematurely wipe off oil when drawn into the unit. Pickup rates vary from 1 quart/hour to 1.5 gph, depending on diameter and speed. These units can be used where space is limited. Units that have the motor mounted underneath reduce the amount of space required over the rim of the tank to nearly zero.

Have you ever had your clean parts rejected from your customer? Parts that have been cleaned in your parts washers, yet they still have residual oils on them? This happened to one of my customers recently, and it’s not uncommon. Fortunately, there is a simple solution that will save you time, money, and embarrassment of having parts rejected.

Tote-It Belt Oil Skimmer

Abanaki Tote-It Belt Oil Skimmer will remove the oil that is floating on the surface of the parts washer and is being reintroduced onto the clean parts when they are removed from the parts washer. The Tote-It belt oil skimmer removes up to 12 gallons per hour of oil from water, and it is made to withstand the high temperatures and pH levels that can be associated with parts washers.

With its patented design, the Tote-It belt oil skimmer is a dependable and effective means of removing oil from water. The single assembly unit can be used in any application where 115 VAC, 60 Hz power is available.

Belt Oil Skimmer Specifications

The Tote-It belt oil skimmer utilizes a continuous belt and wiper to remove up to 12 gallons of oil per hour from the fluid surface. The belt operates on a motor and pulley system attached to a stabilizer bar that is immersed in the contaminated liquid. After traveling over the head pulley, the belt passes through tandem wiper blades where oil is scraped off both sides of the belt, and discharged through a 1-1/4 in. ID hose. The tail pulley has flanges which allow it to roll freely on the inside of the belt without becoming dislodged. It does not need to be fastened to the tank.

Advantages of Belt Oil Skimmer

The Tote-It belt oil skimmer is especially well suited for parts washing and machining center applications. By removing surface oil from a wash tank, the parts will not be re-contaminated as they are withdrawn. Removing tramp oil from a coolant tank prevents excessive smoke and fumes due to oil burning during cutting operations. It also reduces bacteria growth in the tank, along with the resulting odor.

Oil Skimmers are simple, dependable and effective tools for removing oil, grease and other hydrocarbons from water and can pay for themselves within a few months.

When properly selected and applied, oil skimmers are a highly economical solutions for separating oil from water to allow its reuse or safe disposal.

All oil skimmers rely on the fluid properties of specific gravity and surface tension although designs may vary. Most use a moving medium to remove floating oil from a liquid surface. Floating oil and grease cling to skimming media more readily than the water. This allows media (in the shape of a belt, disk, drum, etc.) to pass through the fluid surface to pick up floating oil and grease while leaving most of the water behind. The oily material is subsequently removed from the media with wiper blades or pinch rollers.

Grease Skimming

Grease skimming involves higher viscosity hydrocarbons. These skimmers must be operated at higher temperatures to keep the grease fluid. This may require heating elements in the reservoir and skimmer unit to keep the grease in a liquid state for easier pick-up and discharge. If the floating grease forms solid clumps or mats in the reservoir, a spray bar, aerator or other mechanical apparatus can be used to break up the grease and facilitate skimming.

Often, a skimmer by itself can achieve the required level of water purity. For more demanding situations, skimming is a cost-effective pretreatment before more complicated and costly treatments, such as coalescers, membrane filters and chemical processes are employed.

Oil skimmers are simple, dependable and effective tools for removing oil, grease and other hydrocarbons from water. They usually pay for themselves within a few months. In order to ensure the oil skimmer you choose is right for your operation, there are certain steps you can follow.

Understand the Basics

First, understand that while designs vary, all oil skimmers rely on the fluid properties of specific gravity and surface tension. Most use a moving medium to remove floating oil from the fluid's surface. Floating oil and grease cling to skimming media more readily than water. This allows media in the shape of a belt, disk, drum, etc. to pass through the fluid surface and pick up floating oil and grease while rejecting most of the water. The oily material is subsequently removed from the media with wiper blades or pinch rollers.

Ensure Your Application Applies

When properly selected and applied, oil skimmers are highly economical solutions for separating oil from water to allow its reuse or safe disposal. However, there are certain applications that can expect optimal results. Typical applications best suited for oil skimmers encompass wastewater sumps, coolants and cutting fluids, heat treating operations, parts washers, food processing facilities, parking lots, garages, service facilities, outdoor ponds/lakes/basins, recovery/monitoring wells, remediation processes, and many more.

Select by Application

There are several types of industrial oil skimmers. Choosing one best suited for your application will maximize oil removal while minimizing capital outlay and skimmer operating costs. You may define the application in terms of the following characteristics: operating Conditions, hazardous materials, temperature/viscosity, skimmed water content, residual oil, portability, tank or sump characteristics, size/design, shape, and location/installation.

Determine the Right Design

For industrial oil skimming, there are six basic designs commonly used in moving media skimmers. (Suction skimmers are excluded, as they are generally unsuitable except for relatively thick (1/4 inch) layers of oil; otherwise they tend to ingest large amounts of water.) In more demanding situations, skimming is a cost-effective means of removing most of the oil before using more complicated and costly treatments, such as coalescers, membrane filters and chemical processes.

Consider All the Options

All moving media skimmers use motors to move the belt, tube, disk, etc. While many are designed with standard, industrially rated, continuous-duty motors and also may use fully enclosed speed reducing drives, some can be specified with a number of motor options. Consider also any optional equipment that may be available with the skimmer you are evaluating. Accessories allow customized systems that can ease installation and optimize performance. Some of the more common options include: special drive components, mounting stands and adapters, shelters/ enclosures, controls/accessories, concentrator, and heaters.

An oil skimmer is a device that uses a belt, tube, or disk placed directly into the product containing oil. The belt, tube, or disk attracts the oil by breaking the surface tension of the water and then runs back to the machine to be wiped clean. If your skimmer is sized right, it will be able to pull the free-floating oil from anywhere in the tank or pit. Oil skimmers should be purchased more by size than by the volume of oil to ensure you are able to skim from the whole surface area.

What Size of Oil Skimmer You Should Purchase?

Oil skimmers operate with a very basic principle. That basic principle is the breaking of surface tension to attract oil to the belt or tube. Because of this design, it is critical to size the oil skimmer according to the surface area being skimmed rather than the amount of oil in the tank.

For example, you could have a tank or pit that measure 144 square feet but only contains 2-4 gallons of oil at any particular time. Sizing the oil skimmer according to 2-4 gallons versus the surface area would yield unproductive results. Yes, you may only have small amounts of oil, but if your oil skimmer is undersized, that oil skimmer will not have enough power to break the surface tension with enough force to bring oil from the other side of the tank.

Therefore, you could run the oil skimmer for days and never retrieve the oil from the far side of your collection point. Always take into account how large of an area you want to skim oil from when determining what oil skimmer will work best for your application.

Wastewater Sumps

Most manufacturing or processing facilities have water systems where waste oil collects in a central tank or sump. Skimming the floating oils with little water content can reduce the cost of disposal and lower the contingent liabilities of wastewater discharge.

Coolants and Cutting Fluids

When machine coolants become contaminated with tramp oils, four things usually occur:

• Coolant life is reduced.
• Quality of machined parts is reduced.
• In many cases, a smoke will begin to appear in the shop, causing irritation to the workers on the job.
• The fluid takes on a “rotten egg” odor.

Oil skimmers that remove tramp oils solve these problems and typically pay for themselves within a few months.

Heat Treating

Quench oils that must be removed from heat treated parts can be captured for re-use or disposal. The results are lower quench oil costs, prolonged wash water life and lower disposal costs.

Parts Washers

Floating oils re-contaminate parts as they are removed from a wash tank. Oil skimmers can remove this oil. The benefits of using an oil skimmer are oil free parts and extended fluid life.

Food Processing Facilities

Removal of vegetable oils, greases, and animal fats from a plant’s wastewater stream reduces the costs of processing and disposal.

Steel Mills/Scale Pits

Most steel mills have scale pits in which grease and heavy oils accumulate. In order to avoid fines from the government and expensive sand bed filters, steel mills must limit the amount of grease in wastewater discharged into the environment. Reclaimed grease and oil can be re-used or used as furnace fuel, avoiding sucker truck disposal costs.

Parking Lots, Garages and Service Facilities

Waste oil from leaks, spills and other sources must be retrieved from sumps before water can be discharged to storm or sanitary sewers.

Outdoor Ponds, Lakes, Basins, Etc.

Where floating oils are present, oil skimmers provide inexpensive and effective removal, solving a serious environmental problem.

Recovery/Monitoring Wells

Removing oil, fuel and other hydrocarbon liquid from wells can be more cost-effective using a belt skimmer instead of a down well pump. Oil skimmers don’t have nearly the maintenance issues and can reach depths of 100 feet or more, removing product despite fluctuating water tables. Oil skimmers can handle very thick fluids effortlessly and some (like the Abanaki PetroXtractor®) can remove sinking DNAPL’s such as coal tar and creosote from water.

For industrial oil skimming, there are six basic designs commonly used:

1. Belt Skimmers
2. Disk Skimmers
3. Drum/Barrel Styles
4. Mop Skimmers
5. Tube Skimmers (Large and Mini)
6. Floating Suction Skimmers

Belt Oil Skimmers

Belt-type oil skimmers use an endless belt of corrosion resistant steel or synthetic medium, which is lowered into the tank or vessel to be skimmed. The belt passes through resilient wiper blades where the oil is removed from both sides of the medium.

Belt machines provide a simple, dependable and cost-effective method for removing oil, grease and other hydrocarbons from water.

Disk Oil Skimmers

These oil skimmers rotate a disk-shaped medium through the liquid. Oil is wiped off and discharged into a collection container in a manner similar to belt oil skimmers. It is important to consider reach, the portion of the disk that actually gets immersed,

when looking at a disk oil skimmer. Less disk in the fluid means less oil removed. Obviously, fluctuating fluids can be a real problem for disk oil skimmers.

Drum/Barrel Styles

These are similar to the disk type, but use a rotating drum shaped medium. Compared to disk types, they are usually more rugged and have higher removal capacity. Depending on the design, these units can also be rendered ineffective by fluctuating fluid levels. Also, water pickup with this type of oil skimmer can be high.

Mop Oil Skimmers

These oil skimmers use an endless medium shaped like a rope and having mop-like tendrils that pick up the oil. As the medium leaves the liquid and enters the drive unit, it is pressed and wrung out with pinch rollers. For higher viscosity oils, the medium tends to mat down and lose effectiveness. A decant system is a must for these units, as water pickup can be very high. Also, replacement oil mops can be very expensive, so check prices on replacements before purchasing.

Tube Skimmers

Large Tube Skimmers

Tube oil skimmers use a floating plastic hose that snakes out over the surface of the liquid and is then drawn back through the drive unit where oil is removed. This design requires a relatively large amount of surface area for proper operation. This oil skimmer can skim from very shallow tanks. As a rule, the removal capacity is lower than belt, drum or mop type oil skimmers.

Mini Tube

Very similar to the large tube units, but use either a 3/16″ or a 5/16″ tube instead of 1″. The pickup rate varies from 1 quart/hour to 1.5 gph depending on the diameter of the tube. These tube skimmers are fairly compact, and can fit in tight spots. The better units will have the motor mounted underneath, to bring room required over the lip of the tank down to near zero. The 5/16″ diameter tube is preferable as it has a 1 gph removal capacity and enough stiffness to not drag on the housing and prematurely wipe off oil when being drawn into the unit.

Floating Suction Skimmers

These come in several forms, but all have a floating intake. They are most suitable for relatively thick layers of oil (1/4 inch or higher); otherwise, they tend to ingest large amounts of water. Some machines will actually emulsify oil due to churning as it passes through the suction pump. This type of oil skimmer requires a coalescing or at least a decanting unit to be at all effective. The standard drive on all units is an electric motor and gear reducer. Other drive types available.
