Many oil fires have resulted from the crude oil train derailments in recent\nyears. Given the importance of crude oil shipping by rail to the energy\nsecurity of the US, it is important to consider various methods that will\ndecrease the likelihood of crude oil catching fire in case of a crude oil\nderailment. Present study examines the effect of polybutadiene polymer on the\ncombustion properties and soot deposits of Bakken and Pennsylvania crudes.\nTreating these crudes as multicomponent liquid fuels and polybutadiene as an\nadditive, droplet combustion experiments were conducted with sub-millimeter\nsized spherical droplets suspended on very fine support fibers. Polybutadiene\npolymer additive of two different chain lengths has been investigated. Results\nshow that both polymer chain length and origin of crude oil have a significant\neffect on various combustion properties like combustion rate, ignition delay,\ntotal combustion time, and flame stand-off ratio. Polymeric additives also\nchange the soot deposit structure and particle size compared to the base fuel.\nPresent research is envisioned to aid in theoretical combustion modeling of\ncomplex multicomponent liquid fuels, as well as generate interest in\ninvestigating more polymeric additives for liquid fuels.\n
