CO-718 Series Cartridges for Fuel and Oil Treatment Attapulgus clay canisters for removal of surfactants from jet fuel and other petroleum products Clay Canister Cartridges - Data Sheet #1231 View Clarifier Article (April 2002--Page3) The Velcon CO-718 Series elements are intended for use in all clay treatment vessels designed for nominal 7” x 18” cartridges. The treatment/purification medium is a special blend of low volatile materials (LVM) fuller’s earth compounded to provide the optimum balance between adsorptive capacity and water resistance. With their ability to prevent channeling and their high particle structure stability, the elements assure reliable performance and long life in the most exacting process applications. Jet Fuel Treatment – One of the most common uses for clay elements is to remove surfactants from jet fuels. Surfactants can carry over from the refinery process or be picked up when the jet fuel travels through multiproduct pipelines (corrosion inhibitors, gasoline additives, etc.). Surfactants will eventually disarm filter/separators, which are primarily designed to remove water from the jet fuel. By removing surfactants from the fuel, the clay elements protect the downstream filter/separators. Since clay removes the surfactants by an adsorbent (adhering) action, the fuel residence time, or time in contact with the clay, is very important for proper fuel treatment. Normally, a flow rate of about 6.5 gpm per 7” x 18” element is ideal for jet fuel.
