Reducing Flammability for Bakken Crude Oil for Train Transport: Year 5

Crude oil shipping by rail is a critical component of our energy security and has grown steadily with the Bakken oil boom. However, existing rail infrastructures are in a state of disrepair, which has been evidenced in recent years by several high-profile derailments of trains carrying crude oil, resulting in large oil spills. This is an especially dangerous situation in the case of Bakken crude, which is a light variety and contains significant amounts of easy-to-evaporate, easy-to-ignite light ends, and usually results is an intense fireball in the case of accidents. This research proposal considers a solution to improve fire safety during transportation: adding long-chain polymers to crude oil before shipping. Previous research done by Professor Albert Ratner’s research group under MATC-DOT sponsorship has concluded that polymeric additives improve fire safety in diesel fuels and its blends by delaying ignition, promoting flame extinction, and suppressing splashing. In Years 1-4 of the project, surrogates for the Bakken crude were identified and tested for their ability to suspend polymers and nanoparticles that will serve as fire-limiting agents. In addition, combustion behaviors such as ignition delay, combustion rate, and flame characteristics were experimentally investigated. To provide a broader understanding, testing included crudes sourced from the Bakken formation, Colorado, Pennsylvania, and Texas. Combustion characteristics were established for surrogate fuels with various polymeric additives and carbon-based nano-additives at various concentrations. Also, the stability/settling characteristics were investigated with different surrogate fuels containing nano-additives. In Year 5, the primary effort will be to study how to achieve prolonged stability for fuels with nano-additives (carbon-based nanomaterial/nanoparticles, polymers, and their mixture) because long stability periods are a prerequisite for practical application. In addition, combustion characteristics will be investigated for mixed additives (mixture of carbon-based nanomaterial/nanoparticles and polymers) for different surrogate fuels and crudes to exploit their individual, fire-safety-enhancing characteristics. These results will allow for this information to be linked with surrogate and crude properties. This information is critical for enabling adoption of this technology.
