Effectiveness of water spray mitigation systems for accidental releases of hydrogen fluoride
Accidental releases of Hydrogen Flouride (HF) can result in initally dense, highly reactive and corrosive clouds. These clouds will typically contain a mixture of HF vapor, aerosol and droplets which can be transported significant distances downwind before lower hazard levels of HF concentration are reached. Previous experiments were performed to study atmospheric dispersion of these HF clouds. The present study examines the effect of water application on the mitigation of these clouds. To assess the effectiveness of water application (via either sprays or monitor) in mitigating HF clouds two series of tests were conducted in separate flow chambers. Bench scale experiments identified key variables for testing in a larger facility. The larger scale field tests demonstrated that HF releases can be mitigated with water. The impact of numerous design variables on mitigation effectiveness has also been quantified. HF removal efficiencies of 25 to 90+% have been demonstrated at water to HF liquid ratios of 6/1 to 40/1 and higher. 8 refs., 69 figs., 49 tabs.
