INVESTIGATION OF THE BEHAVIOR OF LPG ESCAPING INTO THE OPEN AIR--2. EXPERIMENTS WITH LIQUID PROPANE AND BUTANE, EVALUATION, AND CONCLUSIONS

For liquid propane escaping at a rate of 325 kg/hr in the direction of a 203 m/sec wind, the maximum ignition distance was 7-8 m; against the wind, it was 5 m. For butane escaping at a rate of 229 kg/hr in the direction of a 2-3 m/sec wind, the maximum ignition distance was 5-6 m; at a rate of 673 kg/hr against the wind, it was at the stagnation point. The results for gaseous propane could be approximated by free jet equations; teh maximum ignition distance of gaseous butane was calculated to be somewhat greater than for propane. The results of the ignition tests with liquid propane and butane were correlated with the escaping quantity and wind velocity to obtain an equation with empirical factors for estimating the maximum ignition distance. This was approximately 8 m with, and approximately 7.5 m against, a 1 m/sec wind for a discharge of 180 kg/hr of propane or butane.
