F-111 Jet Fuel Reclaim System

The F-111 Jet Fuel Reclaim System is a skid-mounted, stand alone device for the reclaiming of waste jet fuel. This waste fuel is usually obtained from tank bottom sumps, filter separator sumps, and other drains used solely for collecting JP-4, JP-5, Jet-A, and JP-8 jet turbine fuels. This waste collection system should be located away from any potential contamination, such as hydraulic oil, glycols, lube oils, or crankcase drains.

The F-111 is designed to purify large quantities of jet fuel contaminated with water and particulate matter. The purified jet fuel is sent to separate storage system. The F-111 will not separate or "crack" fuel oils, diesel, gasoline, etc. from the jet fuel. Purification takes place in a working tank. Once clean, the fuel is transferred to a clean storage tank. From the clean or ready tank the fuel can be dispensed at 100 gpm for use as fuel for aircraft or ground support equipment.

How the unit works
The operator will bring up to 1,000 gallons of contaminated fuel to the F-111. A selector valve is provided to off-load this contaminated fuel into the working tank.

The F-111 will separate very high water concentrations from the jet fuel, and once cleaned, transfer the fuel to a separate storage system. The inlet to the F-111 is connected to the bottom of the waste holding tank (also called the working tank). The fuel is re-circulated to remove all the water and particulate matter. Once the fuel has been adequately cleaned, a test is be performed to ensure the fuel is satisfactory. The clean fuel is pumped out of the waste holding tank, through the F-111, and into the clean fuel storage tank (also called the ready tank).

Water that is drained from the F-111 goes through a secondary filter to ensure no fuel is entrained in the wastewater. Any fuel that does get carried through with the water is separated and sent back to the working tank. The clean wastewater is collected in a five gallon tank that is drained and sent to the proper waste site. If more than 5 gallons of water are separated, the unit will shut down until the water is drained.

The F-111 consists of a multiple stage filtration to remove dirt and water. The stages are as follows:

Filter Dehydrator
This vessel is used for gross water and dirt removal. It is a two-stage vessel, with an automatic water drain. The first stage element is an Excelsior repack. The second stage element is a Teflon-coated separator.

Micronic Filter
This stage is comprised of two filter vessels mounted in series. These filters are used to remove particles from the fuel and make sure that particulate matter does not enter the Coalescer/Separator stage.

Coalescer/Separator
This is the final stage for water removal. It contains an automatic water drain device to remove the separated water automatically.

Final Filter
This filter is a safety feature for the Model F-111. This filter uses a special element that will absorb any water that was not removed in the earlier stages. This filter will prevent any contaminated fuel to enter the clean fuel system.

Fuel/Water Separator
The water that is discharged from the Filter Dehydrator and Coalescer/Separator is discharged through this vessel to strip any fuel from the discharge water. This fuel then returned to the working tank to be further processed and saved.
