Consequence modeling of Ethyl Acetate storage tank

Abstract

Consequence modeling of ethyl acetate 40 KL aboveground storage tank was carried out under different scenarios. The toxic concentration of ethyl acetate beyond IDLH (i.e. 2000 ppm) covered up to 23 meters from the release source when there was a leak that occurred 2 inches from the bottom of the tank. The flammable vapor cloud enveloped up to 13 meters from the release source when the concentration of ethyl acetate was beyond 60% of LEL (i.e.13080 ppm). The mass of the fire ball was considered as 100% in order to get the worst case scenario during BLEVE. Based on the mass of the methyl acetate the diameter and duration of the fire ball was 190 meters and 12 seconds respectively during BELVE.
