SIMULATE DUST DISPERSION AREA AT LONG SON CEMENT FACTORY

Abstract

This article displays the result of utilising modeling method in simulating the area and concentration of dust dispersion at Long Son cement factory, with a capacity of 2.3 million tons/year. In both cases: When the dust filtering system working as intended (using Gauss and ArcView); and when the dust filtering system malfunction and fail to cleanse the dust (using Berliand and ArcView). The results show: When the dust processing system working properly, at all distances and different dispersion locations, the concentration of dust in the air is with in limit of 23:2009/BTNMT National Standards. In the event of production procedure failure and dust filtering system malfunction, the concentration of dust in the air is 3.2-8 times above the acceptable level with a radius from 500 -1600 m. At a distance less than 500m and more than 1600 m, dust congregation isn’t as great but it’s still 1.5-3 times above the suitable level for an unpolluted environment. At a radius greater than 3000 m, in general, the air quality isn’t affected by the dust from the cement factory.
