Welcome to the Section
on VOLATILE ORGANIC COMPOUNDS, PARTICULATE MATTER & ODOR
This Section covers the following:
Introduction - Primary vs. secondary pollutants, Criteria
Air Pollutants, Particulate Matter, Hazardous Air Pollutants
VOC - Volatile Organic Compounds
- VOC - Industry and Sources, basic properties: vapor
pressure, water solubility, ionization, reactivity, etc
- Health effects of VOC - Routes of exposure, Target
organs, Acute vs. chronic exposure
- VOC Control - Prevention (Substitution, process modification,
leakage control), Concentration & recovery (Condensation, adsorption,
absorption), Oxidation (thermal, catalytic, biological), Others (Membrane,
UV, plasma)
- Sources of VOC - Process vents, Storage tanks, Loading
& cleaning, fugitive emission, sewer, equipment decommissioning, maintenance,
solid dewatering
- Safety Issues
- Comparison of technologies, selection criteria (pre-treatment
considerations, flowrate and concentration, costs), source minimization vs.
control systems
PM - Particulate Matters
- Definitions of airborne particulates
- Particulate collection mechanisms
- Objectives of particulate collection
- Equipment & operating principles: gravity settler,
cyclone separator, wet scrubber (venture, spray, cyclonic), electrostatic
precipitator, fabric filter)
ODOR
- Definitions: Threshold, odor unit, intensity, pervasiveness,
etc
- Human response & perception
- Odorous compounds & characteristics
- Odor control: oxidation, precipitation, pH, biological,
scavenging sulphur, masking agent, neutralizer, inhibitor
