In Situ Burn Research

Ignition, Combustion and Atomizatin of Emulsions during in situ Burning

The purpose of Sweet Spot in Burning Emulsions project is to study how emulsions break and boil during in situ burning (ISB), which is a multi-physics process that includes radiative and convective heat transfer to the slick, any mechanical work that is driving emulsion formation, hydrocarbon and water evaporation, and internal heat transfer as the water either flash evaporates or separates and sinks. Previous work under OSRR 1085 resulted in a potential trend indicating an increase in burning efficiency in emulsions with 20% water content.

Development of a Floating Flame Refluxer

This latest research initiative on Flame Refluxing technology endeavors to advance the technology readiness towards commercialization (TRL 9) by testing floating Flame Refluxers™ in a controlled-oil spill in an offshore environment. The target burning rate per unit area is 2 to 5 times baseline values with an improvement in emissions (30 - 60% reduction in CO/CO2 ratio) that will reduce black smoke during combustion.

HYSPLIT - In Situ Oil Burn Plume Characterization and Dispersion: Technology Assessment and Worker/Public Safety

This project will conduct field trials of in situ burns (ISB) to calibrate the NOAA's HYSPLIT air trajectory model by conducting multiple crude oil burns at the Poker Flat Research Range (PFRR) operated by the University of Alaska, Fairbanks with oil handling support by Alaska Clean Seas.

Analysis of Emissions and Residue from Methods to Improve Combustion Efficiency of In-Situ Oil Burns

The Environmental Protection Agency's Office of Research and Development (ORD) will peform real-time air emissions and residue testing on two BSEE-sponsored, outdoor in situ burn tests at the Army Corp of Engineer's Cold Regions Research and Engineering Lab (CRREL) in New Hampshire. ORD will assess emission and residue to characterize the combustion efficiency. ORD will also assess emissions on an additional BSEE OSRR project at CRREL and a crude oil combustion study at the Naval Research Laboratory's (NRL) Chesapeake Beach Detachment.

Shoreline Oil Spill Response Gaps and Opportunities Workshop

A workshop is being developed to discuss impacts of oil spills on shorelines. The workshop will bring together Subject Matter Experts (SME) from the spill response community, academia, and industry for the exchange of ideas and the exploration of the current state of the science of oil spill research. Traditional oil and gas exploration and production (E&P) as well as renewable energy (RE) will be explored. The results of this workshop will help guide BSEE Oil Spill Response Research (OSRR) to develop relevant Research and Technologies (R&T) in fulfillment of BSEE's mission.

Advancement of Quantitative Measurements of ISB Volumes and Burn Rates in Open Water

The objective of this project is to enhance an in situ burn (ISB) quantification system previously developed under OSRR Project #1074. The system is designed to provide near real-time quantification of volumes of crude oil being burned thus yielding burn rate and efficiency. A series of small- and large-scale test burns will be conducted to acquire data for algorithms to accurately measure and quantify burning volumes and efficiencies to advance the state of maturity of the technology for commercialization.

Efficient Remediation of Oil Spills using Fire Whirls – Phase II

The objectives of this project are to 1) characterize the ideal configurations and parameters of fire whirl formation; 2) characterize the effects and burning/combustion efficiencies on emissions from different fire whirl configurations, fuels, and slick thicknesses; 3) further understand the fundamental physics contributing to enhancement in the combustion efficiency of fire whirls verses pool fires; and 4) develop a scaled prototype fire whirl generator for use in a large-scale outdoor test facility.

Restricted Burning Tongue

BSEE is pursuing a line of research and plans to conduct full-scale tests of modified boom configurations in the Canadian Multi-Partner Research Initiative Offshore Burn Experiments (MOBE) planned for the summer of 2022. The primary goal of the research is to determine if alternate boom geometries will result in a reduction of particulate matter (PM) and trace pollutants in the plume and reduced amounts of burn residue.
