Abstract:

Research has shown that burning can be an effective means to remove oil from the surface of the water after a spill. Previous research has focused on laboratory studies of combustion products from oil pool fires less than 1 meter in diameter. This paper describes instrument packages developed to determine the amount of various combustion products emitted from large (15 m x 15 m) crude oil pool fires. Based on samples drawn directly from the smoke plume immediately downstream of the flame, burning a mixture of Arabian light and Murban crude oils in a 2.7 m x 2.7 m pan produces a smoke yield of 0.15. Preliminary results from burning Louisiana crude in a 6 m x 6 m pan indicate a similar 0.14 of the crude oil is converted to smoke in the combustion process. The increase in burning rate and smoke production with increasing fire size is discussed. Progress is reported on new calculation methods for smoke dispersion and downwind deposition of particulate. Results of example calculations are presented.
