Transfer of BioDiesel and BioFuels Using Composite Hose

BioDiesel and Biofuel transfer is increasingly important in the petrochemical industry. Bioethanol presents few problems since most rubbers and thermoplastics have generally good chemical resistance. However, Biodiesel contains Esterified vegetable oils which have been found to damage most elastomers typically used in the production of fuel oil hoses. Composite hose, on the other hand, can be lined with polyamide (Nylon), which has excellent resistance to both mineral oils and the component chemicals which constitute typical Biofuels. Dantec and Accord International have received much interest concerning the transfer of Biofuels, from bulk fuel storage and transport companies throughout the world.

As well as nitrile; polypropylene, polyvinyl, and tygon materials are also vulnerable to problems. Brass, bronze, copper, lead, tin and zinc may accelerate the oxidation of diesel and biodiesel fuels, and create fuel insolubles (sediments), or gels and salts when reacted with some fuel components. All lead solders, zinc linings, copper pipes, brass regulators, and any copper fittings should be avoided. Recommended equipment should be stainless steel, carbon steel, or aluminum.

The hose we offer for these media is the Danoil 9 NG, AG, or SG hose which is available from 1" to 10" bore, maximum working pressure is to 14-Bar (200 PSI) and with its nylon lining possesses excellent resistance to Biodiesel and alcohols.

Composite hose is particularly suitable for these applications because of its excellent chemical resistance and its relative lightweight flexibility.
