A Review on Application of Dispersion Models for an Industrial Point Source using AerscreenEZ

Air pollution has been an alarming concern and a threat to our ecosystem since the beginning of the industrial revolution. To combat its ill effects, the first step is to know its concentration and behavior in air. This is done by finding its dispersion in air using different softwares. Such softwares run a predefined algorithm based on various mathematical dispersion models using values given by user. AerscreenEZ is one such software which creates a dispersion scenario of a pollutant using AERMOD atmospheric dispersion model around the source. The basis of AERMOD model is the Gaussian plume dispersion model. Here, various screening softwares based on the Gaussian atmospheric dispersion model are being reviewed with focus on application of AerscreenEZ for point source. The values of stack height, stack diameter, emission concentration, gas emission velocity, stack temperature and the prevailing meteorological conditions are given as input. The output obtained is in a graph form where concentration (y-axis) v/s distance (x-axis) is plotted which indicates the dispersion of the emitted pollutant from the point source in its surrounding, Citation: Prasanna Kumar Tiwari, Kevin Bhikadia, Prof. Hemali J.
