Prediction of Hazards of Spills of Anhydrous Ammonia on Water.

摘要

Maritime transport of liquid anhydrous ammonia (LNH3) poses a potential hazard to the public,to aquatic life,and to other shipping should there be an accidental surface or underwater release of ammonia. This report contains the results of an experimental and analytical program aimed at evaluating the hazards presented by a 3,000ton release of liquid anhydrous ammonia on water. Test spills were conducted in the laboratory (up to 1/2gallons),in a swimming pool (5gallons) and in a lake (50gallon size) and the fraction of released ammonia dissolving in water and the amount vaporizing were determined. The dispersion of vapor in air was measured and a theory was developed to predict the movement. Analytical models to predict water dispersion are also presented. (Modified author abstract)
