Simulating Ambient SO2 Dispersion Patterns and Assessing their Health Risk in a Gas Refinery

Abstract

The emission of pollutants in a gas refinery depends on some factors, including refinery age, location, capacity, specifications of the feedstock, types of products, and the complexity of the operating units. Air quality management strategy is of great importance in minimizing the effects of air pollution, especially in places with multiple pollution sources [1]. In general, refineries emit more than 100 types of atmospheric pollutants. These pollutants include dust, metals, carbon monoxide, sulfur dioxide, nitrogen oxides, methane, dioxin, hydrogen fluoride, chloride, benzene, and other harmful gasses [2].
