AIR EMISSIONS OF VOLATILE LIQUIDS SPILLED ON SANDS

Simple laboratory experiments simulating a spill of a volatile liquid on sands were conducted. Hexane was spilled onto both initially dry sa nd and water-wetted sand at nearfield capacity. The experimented condi tions approximated the assumptions of a theory developed by Thibodeaux (1979). Predictions of a modification of this model were generally in good agreement at early times with data on the rate of volatilization . The modified model can be used to estimate air emissions of a volati le liquid spilled on sands.
