Air Quality

Emissions, dispersion and control. Air pollutants and their effects, Gaussian plume dispersion, stack design and emission-control devices.

• Air Pollution — Air pollution harms health and climate. Learn pollutants (PM₂.₅, PM₁₀, SO₂, NOx, CO, O₃), sources and emission estimates, meteorology and dispersion (Gaussian plume, stack height), air-quality standards and AQI, and control devices (cyclones, ESPs, bag filters, scrubbers, SCR).
• Air Pollutant Dispersion & Emission Control Design — How pollutants spread in the atmosphere and how we control them. Learn the atmospheric boundary layer, lapse rates and stability classes, wind profiles, the Gaussian plume model and dispersion coefficients, effective stack height and plume rise, maximum ground-level concentration, stack design, air-quality indices, and control devices (cyclones, bag filters, ESPs, scrubbers, SCR) with efficiency calculations — with Python for a Gaussian plume.
