Because nitrogen is inert and nonflammable, it can help prevent fires or explosions by displacing oxygen in storage vessels and piping used for flammables. Production of biodiesel via the fatty acid methyl ester process typically involves methanol or other alcohol solvents, which are flammable and volatile at normal temperatures and pressures (National Fire Prevention Association rating of 3).
Biodiesel fuel requires minimal fire protection, depending on the feedstock used (NFPA rating of 1). On the other hand, nitrogen inerting/blanketing can extend biodiesel shelf life by reducing exposure to oxidizing and hydrolyzing components of the air.
