Modeling the air pollutant concentration near a cement plant co-processing wastes

Abstract

In this study, we conducted full life-cycle studies on pollutants in a cement plant co-processing hazardous waste (HW) via the combined use of thermodynamic equilibrium calculations and the American Meteorological Society/Environmental Protection Regulatory Model.

Ammonia emissions from livestock facilities around an international airport, Tehran, Iran: An experimental and mathematical study

“…There are three components to the AERMOD algorithm: Dispersion model (AERMIC), the terrain preprocessor (AERMAP), and the preprocessor for meteorological data (AERMET) 24 . AERMOD is applicable to both flat and complicated terrains, inside urban and rural areas impacted by numerous surface and heightened emission sources, such as point, area, and volume 25 . AERMOD is able to characterize the planetary boundary layer (PBL) through the surface and mixed layer scaling and the concentration distribution in the stable boundary layer (SBL) is presumed to be a Gaussian distribution horizontally as well as vertically.…”

“…24 AERMOD is applicable to both flat and complicated terrains, inside urban and rural areas impacted by numerous surface and heightened emission sources, such as point, area, and volume. 25 AERMOD is able to characterize the planetary boundary layer (PBL) through the surface and mixed layer scaling and the concentration distribution in the stable boundary layer (SBL) is presumed to be a Gaussian distribution horizontally as well as vertically. Horizontal distribution in the convective boundary layer (CBL) is considered Gaussian, whereas vertical distribution is supposed to be a bi-Gaussian probability density function.…”
